Training has always been important in the heating sector, not least of all because of the dangers associated with working with gas, the traditionally dominant heating fuel in the UK. With the changes that are occurring across the heating industry, primarily the move towards decarbonization, manifesting in a transition to heat pumps, training is more important than ever. Principles of heat pump technology Training could take the form of a CPD on understanding the guides of heat pump technology That training could take the form of a CPD on understanding the principles of heat pump technology through to specific product training addressing installation, commissioning, and maintenance. Commercial heating training courses are abundant. Unless there is a specific manufacturer’s product you want to train on, how do you choose a training course and provider that is right for you? Here, we look at the key aspects to consider when selecting a training course and training provider. Expertise & knowledge By far the most important aspect of any training is the level of expertise and knowledge of the training providers. The training course needs to be both written and delivered by people who have direct experience in the heating industry. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For contractor-based training, ideally, the trainers will have a background in heating engineering. This enables them to not only cover the core content of a training course but also address how it applies in real working-life situations. Knowledge or qualifications in training techniques and knowledge transfer are equally important. For specifiers looking to expand their knowledge through CPD courses, it’s helpful if these are presented by experienced Specification Managers who understand the needs of a specifier and have extensive knowledge of heating systems. On-site facilities The environment itself plays an important role in the success of the training The environment in which you learn plays an important role in the success (or otherwise) of the training itself, which is often overlooked. Being in a comfortable environment free from distractions will support you to better focus on your learning. Is the training held in a dedicated training center or a makeshift back office room? Is it a comfortable environment in terms of seating, desks, heating/air conditioning? Is the presentation equipment up to scratch? But most important of all, is the heating equipment you are learning about present, and is it functional? Training and Technology Centers  At our Training and Technology Centers, we provide learners with on-site access to a range of commercial heating equipment, including a unique thermodynamic heat pump simulator where they can view the change of state of refrigerant when in operation. Hands-on training for contractors is vital as it enables more learning by doing and problem solving, and therefore, greater depths of understanding can be gained. In our feedback survey, this comes up as one of the most important and popular aspects. It’s one thing to have something presented to you, but to be able to work through scenarios with expert support is quite another. Hands-on training for contractors is vital as it enables more learning by doing and problem-solving. Location A CIBSE-approved CPD, for example, doesn’t require hands-on training We’ve looked at the importance of how a training course is delivered, but where it is delivered also has a role to play. Does the training provider have training facilities nationwide, or in just one location? The latter could make for long travel times and even an overnight stay. Ideal Expert Academies are located around the UK at Hull, Leeds, Dalgety Bay, and Luton. Lastly, not all training needs to be done in person. A CIBSE-approved CPD, for example, doesn’t require hands-on training. In these instances, online training is a good, convenient option. Will the training provider be able to deliver this and how? Is it just a PowerPoint presentation, or are other elements included, such as video, attendee tasks, etc? Range of courses and delivery Having a range of courses is obviously important in that it provides you with choice and allows you to fill in the gaps of your knowledge, as well as learning about emerging technologies and best practices. A good training provider will also provide a flexible delivery model to meet individual learner needs and have the knowledge and expertise to support those with learning difficulties. Good training provider also provides a flexible delivery model to meet individual learner needs. Endorsement Ideal Heating’s adult learning provision was assessed by Ofsted, and they received an excellent report Whilst it’s important to do your own ‘homework’ on training providers, third-party endorsements are very useful. These come in different forms, from customer feedback (there are plenty of forums that provide you with the opportunity to ask for feedback), through to recognized industry awards, and independent assessment. Last year, Ideal Heating’s adult learning provision was assessed by Ofsted, and we received an excellent report, plus our Expert Academy team was recognized as Training Partner of 2024 by Hull City Council for delivering Skills Bootcamp programs for hundreds of learners in the area. We were also delighted to receive the inaugural BESA award for Training Provider of the Year 2024. Cost The last aspect I want to touch on when it comes to training is cost. How much should you pay for training? You should really consider the value you believe will be returned from the program and the provider you choose.  If you are going to benefit from state-of-the-art facilities, you may probably expect that experience may cost more than somewhere very simple and basic. Training providers are businesses, and the good ones do invest heavily in facilities and staff development. The good ones do invest heavily in facilities and staff development. Ideal Heating as a manufacturer strongly believe that our training services are part of what we deliver in our product sales. For this reason, we provide many of our training programs for free or at very low cost, despite the significant investment into our resources. Working alongside our specifiers and installers to meet their training needs builds for a strong relationship and successful projects. Choose wisely Taking time out from your busy schedule to dedicate to training is an investment, financially in some cases, so selecting your training course wisely to maximize that investment is sensible.

Data centers worldwide are under intense pressure. High-powered computing is a global necessity that seemingly gets more demanding by the day. There’s also the need to prioritize sustainability improvements ranging from resource conservation to decarbonization. And data centers must consider their bottom line and remain competitive. Anticipating the challenges data centers will continue to face, scientists and engineers have innovated two-phase (2-PIC) immersion cooling. With the capacity to meet the elevated cooling requirements driven by high-powered computing, this next-generation solution delivers on environmental priorities by significantly lowering data center energy consumption, slashing, if not eliminating, water use, while supporting decarbonization, circularity missions, and more. Emergence of 2-PIC Traditional approaches are fast approaching capacity for meeting current and future cooling needs The emergence of 2-PIC comes at a critical time, because the traditional cooling methods that have kept data centers up and running so far—namely air cooling and water cooling—are doing so at the detriment of the planet.  Additionally, these traditional approaches are quickly approaching capacity for meeting current and future cooling needs. Air- and water-cooling methods are used in approximately 95% of the estimated 8,000 data centers that exist today. The criticality of high-powered computing Once seen as a future need, high-powered computing, and faster-than-ever processing are now established as critical to the operation of businesses, governments, organizations, and other entities that support the way communities function, survive, and thrive. Whether it’s health and wellness, financial institutions, economic growth, safety and protection, entertainment, education, or any other service supporting our way of life, successfully providing that service fully depends on the ability of data centers to quickly and reliably obtain, store, and process data.  Influence of AI AI has a profound influence and, generates far more power than traditional internet uses Moreover, when we say “data centers,” we’re not just speaking of big players like Microsoft, Google, Meta, and Amazon. Equally dependent on high-performance, high-speed computing are enterprise data center operators, such as our governments and military, financial institutions, healthcare systems, educational institutions, and more.  We also must acknowledge the profound influence of artificial intelligence (AI), which generates far more power than traditional internet uses. Its effects are far-reaching, enhancing patient care, supporting risk management and fraud detection in finance, boosting crop yields within agriculture, and more. The environmental costs of data centers According to the latest estimates by the International Energy Agency, data centers worldwide produce 1% of energy-related carbon emissions and in 2022 used approximately 460 TWh of electricity per year—equating to 2% of global electricity demand. McKinsey and Company estimates 40% of this electricity is used for data center cooling. Data centers’ impact on the environment also includes their significant water consumption, averaging 300,000 gallons per day, and a physical footprint that averages 100,000 square feet but in the case of some hyperscale data centers can range between 1.3 to 2 million square feet. In terms of growth, a U.S. market report from Newmark tells us that in the U.S. alone, the U.S. data center footprint will absorb 35 gigawatts by 2030, which is more than twice the data center power consumption of 2022. The emergence of liquid cooling: the elevated interest in 2-PIC From reducing energy and water consumption to shrinking physical footprints, 2-PIC offers the planet a better data center solution. In less than two years, traditional cooling systems won’t be able to support the exponential growth in the world’s data processing and storage applications. Based on publicly available product roadmaps from major chip manufacturers, by 2026, air-cooled systems will no longer be able to meet the cooling needs of most next-generation, high-performance computing chips. Capable of removing heat more effectively than air cooling, liquid cooling uses a liquid such as water or a dielectric fluid to cool the heat-generating components of servers. The liquid can cool these components directly, or it can be done indirectly through a heat exchanger. With two-phase immersion cooling the entire server rack is submerged in a tank filled with a dielectric fluid. Single-phase and two-phase liquid cooling Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system Single-phase liquid cooling uses a pump to circulate the liquid through a closed-loop system. Two-phase liquid cooling uses a phase-change material, such as a refrigerant, which evaporates and condenses as it absorbs and releases heat. With 2-PIC, which is a form of two-phase liquid cooling, the entire server rack is submerged in a tank filled with dielectric fluid. The fluid boils as it’s heated by the components of the servers, creating bubbles that rise to the surface and condense in a heat exchanger. Gravity then returns the condensed fluid to the tank, creating a natural circulation loop that does not require pumps or fans. Advantages of 2-PIC 2-PIC is commanding attention as the solution for meeting the cooling demands of the high-powered computing components of today and tomorrow. Moreover, the technology of 2-PIC systems, combined with the right dielectric fluid, delivers advantages to “take the heat off” data centers. Here’s a breakdown of additional 2-PIC benefits: Up to 90% reduction in energy consumption: Based on modeling completed by the industry, 2-PIC is expected to reduce up to 90% of data center cooling energy consumption and 40% of overall data center energy consumption*. (*Compared to traditional air-cooling technologies) Enhanced computing performance and data center reliability: 2-PIC allows servers to operate at higher temperatures and power densities, while reducing the risk of overheating. Significant reduction in water consumption: Depending on the data center location and cooling design methodology, water consumption could even be eliminated completely. 60% reduction in the physical footprint: 2-PIC reduces the space required for cooling equipment, freeing up more floor area for servers and increasing the rack density of the data center. Lower GWP and circularity: Chemours Opteon™ 2P50 is a developmental dielectric heat-transfer fluid, currently pre-commercial, pending regulatory approval. It offers an extremely low global warming potential (GWP) of 10 and was specifically created to optimize the performance of the electronic components in a 2-PIC system. This 2-PIC fluid also enables the reprocessing/reuse of existing fluid to maximize circularity.  The bottom line: In addition to other compelling data, a recent study commissioned by Chemours and LiquidStack through Syska Hennessy, revealed that, compared with other state-of-the-art liquid cooling methods, 2-PIC can deliver up to a 40% lower total cost of ownership (TCO) and significantly reduce operational expenditures (OPEX), with savings ranging from 54% to 88.6%. Benefits of new data center cooling technologies compared to single-phase direct-to-chip, and single-phase immersion methods. 2-PIC, the future-ready solution As the world’s reliance on AI and other high-powered computing capabilities escalates, data center cooling solutions must grow with demand while significantly reducing their impact on the environment. In global energy savings alone, 2-PIC could generate an estimated savings of 340 TWh by 2055—the equivalent of powering more than 517 million laptops 24/7. And even with increasing IT loads, 2-PIC maintains its performance, ensuring long-term cost-effectiveness and adaptability to meet future demands. With society at a crossroads between the criticality of high-powered computing and a planet in crisis, the industry is turning its attention to 2-PIC as the solution for today and tomorrow.

The HVAC market is forecasted to grow at a projected compound annual growth rate (CAGR) of 3.9%, with a prediction to reach $370 billion by 2030. But in reality, the HVAC and plumbing industry is changing rapidly, with operators facing new challenges like never before. Whether it’s rising costs, the uncertain economy, increasing competition, or the workforce shortage, there’s no doubt the HVAC and plumbing market is evolving. So how do you adapt? That’s the key question. My take is that we can’t predict the future, but we can adjust based on the facts on the field. That’s why now is the time for industry operators to focus on strategies that elevate growth, relationships, and longevity. Here are three ways to tackle today’s market. 1. Diversify Service Offerings With the rising costs of customer acquisition and market competitiveness, it is increasingly challenging to build a successful, resilient trade business by just offering one service — especially if it’s a seasonal specialty. While one-service shops were the norm historically, things have changed in the market. The contractor’s relationship with the customer has never been more valuable, and offering multiple trades allows operators to keep relationships within the four walls of the company – without referring valuable leads (or the potential to lose a customer entirely) to the competition. While one-service shops were the norm historically, things have changed in the market By adding more services to your HVAC and plumbing line-up, you become the one-stop, go-to source for essential home services in your market. For the long-term sustainability of the business, it is crucial to ultimately offer the essential three services: electrical, plumbing/sewer, and HVAC. Additionally, when you provide a variety of services your business will experience less seasonal or cyclical highs & lows because it’s well-rounded, diverse, and, ultimately, healthy. 2. Build Scale through Investment It’s a fact: The home services market is highly fragmented, with over 100,000 contracting businesses active in the United States. It also continues to churn out profits — making it a quality investment for home services investors and private equity sponsors. The fragmented market dynamic is an ideal opportunity for consolidation – and there is more investment capital flowing into the market than ever before. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services Nationally, scaled Platforms backed by investors or large franchisors service ~20% of the market in a metro area. The benefits of scale are significant: substantial purchasing power (especially on equipment), robust digital/traditional marketing capabilities, programmatic recruiting/training functions, breadth of service offerings, and robust balance sheet to fund growth and investment – just to name a few. However, not every investor is the same. Many employ business practices inconsistent with the culture of founder/owner-backed businesses, which smart entrepreneurs/operators can use to their advantage. Owners with ambitions to grow can be aggressive with tuck-in acquisitions to offer differentiated services and build breadth/new skills in their businesses. Alternatively, businesses struggling to make it on their own or with owners approaching retirement, can partner with larger service providers so they can keep practicing their trade without having to run the day-to-day business – just be careful with selecting the right investor to protect your people and legacy. 3. React in Real Time One thing the HVAC and plumbing industry has proven over the last few years is its resilience – especially for the best operators. No matter what the economic climate is, homeowners still need to protect and stay comfortable in their most valuable asset. That should provide a sense of job security to HVAC and plumbing professionals — but also motivate you to go the extra mile to attract and retain business. Just because the HVAC and plumbing industry has shown signs of being recession-resistant (for now) does not mean it can’t be impacted by the economy. That’s why it’s crucial to manage the business daily – especially pricing and the components of gross margin. The best operators review cost inputs with their teams weekly and adjust mid-month, which ultimately helps the business maintain its health and profitability. As we head into the back half of 2024, it will be interesting to see how the rest of the year plays out for the industry, and I continue to be optimistic about a bounce back after a tough 2023. We will have to wait and see-but with the strategies above, businesses can position for success no matter what happens in the future.

Hydronics systems rely on water, steam, or water solutions to distribute heating and cooling throughout a building. They are inherently more eco-friendly than conventional alternatives. First and foremost, using water as a temperature regulation method is a natural choice. There is no carbon footprint involved in its creation, and there is no inherent danger in exposure to water in the event of a system failure. Water is more efficient at carrying heating and cooling loads than other technologies. Other benefits include a wider range of maintenance flexibility and longer system life expectancy. overall efficiency of hydronics  “A misconception about hydronics is that it's more expensive compared to other HVAC systems,” says Jim Nolan, market development manager, Xylem. “While hydronic systems may require a larger upfront investment, lifecycle costs are significantly lower due to the overall efficiency of hydronics.” Flexibility in Cold and Warm Climates Hydronics offers a wider range of flexibility for components, operation, and maintenance Compared to other systems, hydronics offers a wider range of flexibility for components, operation, and maintenance. That flexibility also extends to extreme climate conditions, says Nolan. Hydronics perform reliably at very cold and very warm temperatures for improved occupant comfort and reduced energy costs. Additionally, hydronic systems draw on water’s natural thermal storage capabilities, which can substantially offset operating costs during peak demand periods. For over 100 years, Xylem’s Bell & Gossett has been at the forefront of hydronic systems as a manufacturer of pumps, valves, heat exchangers, and accessories — including steam and heat transfer — for plumbing and wastewater applications. Since 1916, the company has made a name for itself through products, industry-pioneering training at the Little Red Schoolhouse, comprehensive solutions, and application expertise, says Nolan. Products and sustainability efforts “Xylem is continuously innovating to advance and embed sustainability holistically into our solutions – from the materials we source, to making them more compact and cutting emissions, to high-efficiency motors,” adds Nolan. Advancing the efficacy and efficiency of their foundational products is what Bell & Gossett is known for, and more broadly, what Xylem is doing to embed “high impact” into all its products and sustainability efforts, says the company. Quantifiable Effect on Decarbonization Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency As the built environment increasingly weighs the effects of climate change and decarbonization, products must keep pace to demonstrate quantifiable impact on addressing these challenges. Smart pump solutions like Xylem’s Hydrovar® X Smart Motor tout ultra-premium efficiency, sustainably sourced materials, and compact design, delivering high impact in terms of intelligence and productivity. Built-in condition monitoring empowers customers to leverage data for additional pump protection and optimized performance. Equally essential is continued education and collaboration with industry partners to help commercial building owners navigate the challenges of achieving decarbonization and net-zero goals, says Nolan. That includes training opportunities at Bell & Gossett’s Little Red Schoolhouse to teach industry professionals about sustainable solutions, he adds. Ideal distribution system “Water is considered technology agnostic – no matter what type of technology exists today or in the future, modern hydronic systems can easily adapt to a variety of energy sources,” says Nolan. “As solar and geothermal grow, building owners and designers are recognizing that hydronics provide an ideal distribution system for these alternative technologies to perform.” Hydronic system efficiency is already well-documented in thousands of real-world applications, says Nolan. Hydronics reduces operating costs by using water as a heat transfer medium, which is more effective than air. Efficiency and cost savings are maximized when these systems are powered by renewable energy sources. Overcoming Obstacles to Equipment Reuse In some cases, though, existing HVAC equipment may be too outdated for reuse In some cases, existing HVAC equipment can be reused to achieve sustainable, carbon-neutral systems, says Nolan. Adaptive reuse projects involve repurposing an existing building for new use and reusing as much existing equipment as possible to save costs, conserve resources, and minimize construction-related disruptions. Upgrading existing hydronic systems with smart technology like advanced controls and smart motors can improve performance and efficiency, says Nolan. Another option is to incorporate high-efficiency components like heat pumps. In some cases, though, existing HVAC equipment may be too outdated for reuse. In others, existing building footprints may limit design options. To overcome this, a thorough assessment of current building conditions and performance can provide a better understanding of the original system design. Identify ways to reduce energy consumption Energy audits, building performance evaluations and environmental impact assessments provide valuable insights into an existing building’s energy consumption, resource usage and environmental footprint. The purpose of these tools is to identify ways to reduce energy consumption or operating costs by upgrading to more energy-efficient equipment or by building a better system. “There’s a whole industry built around energy audits—they’re typically conducted by industry professionals who have qualifications or certifications to ensure they have the knowledge and skills to perform thorough and accurate assessments,” says Nolan. Challenges to Deregulation and Achieving Net Zero Deregulation or the elimination of natural gas in existing buildings presents challenges. While hydronic equipment is essentially decarbonized because it runs on electricity, many utilities still rely on fossil fuels. Only when those providers switch to renewable energy and the grid infrastructure is expanded to deliver enough electricity will environmental impact be realized.  Although many areas are moving toward decarbonization and achieving net-zero energy, in regions where energy is cheap, there are few incentives to embrace renewable energy and building electrification. As HVAC equipment becomes more efficient and uses less energy, communities will realize the cost savings and gravitate toward better technology.

The Olsen Group, based in Boca Raton, Florida, is a national pioneer in HVAC energy optimization. Donald Olsen and his seasoned team of HVAC control specialists have been in business for two decades, integrating energy-saving solutions into over a thousand commercial and large-scale residential projects. In the process, the Olsen Group has become one of North America’s top suppliers of Verdant thermostats. Verdant devices leverage intelligent occupancy sensors and proprietary software to reduce HVAC runtimes by 45 percent on average. HVAC control integration Verdant’s effectiveness, reliability, and broad compatibility have made Verdant the energy management solution of choice for thousands of hotels and MDUs, including multifamily buildings, senior living, and student housing.  The Olsen Group has forged a productive two-way partnership with Verdant. Donald Olsen and his team have made it a priority to share data, customer feedback, and requirements with Verdant – and Verdant, in turn, has come to rely on Olsen when they need to field test a new solution. In May of 2024, Verdant reached out to Olsen for help with a new pilot program aiming to facilitate more effective HVAC control integration, easier service, and deep energy savings for MDU projects around the globe. The Challenge Commercial VRF systems have an extremely attractive set of upsides for hotel operators Inverter (VRF) system design is becoming increasingly common in hospitality settings. Commercial VRF systems have an extremely attractive set of upsides for hotel operators. They are significantly more energy efficient and quieter than traditional VTACs or PTACs; they can provide simultaneous heating and cooling to different zones for optimal guest comfort; and they allow both individual room-level setpoint control and building-level centralized management. However, the majority of VRF units cannot connect directly to a third-party smart thermostat. Because they rely on proprietary manufacturer protocols for variable speed commands and internal diagnostics, VRF units require an external control solution to facilitate bidirectional communication with Verdant thermostats. Installation and commissioning process Every additional component in a system adds complexity and opportunity for human error. In hotels, that complexity is multiplied across hundreds of rooms. “HVAC systems are installed dark for new builds, with no power running to the site,” says Donald Olsen, President and Owner of the Olsen Group. “There’s no way to test as we go. If there are any mistakes during installation, we find out about it when the lights go on after project completion.” And mistakes are nearly inevitable. Some third-party controllers have prominent dipswitches that can be easily snagged or tripped during transportation or installation, altering their configuration and causing them to fail once the system is powered. These switches are often accidentally tripped multiple times throughout the installation and commissioning process, pioneering to a never-ending cycle of errors and service calls. VRF control solutions  Adding to the issue, not all third-party control keys have the ability to retrieve and solve system error codes “Once properly configured and installed, VRF control solutions tend to be incredibly reliable,” says Olsen. “Getting them there is a real challenge, however. Accidents, human error, and repeated recalibrations can drive serious project overruns and client dissatisfaction.” Adding to the problem, not all third-party control solutions have the capability to retrieve and translate system error codes. “If the central management system isn’t getting certified manufacturer control signals from the control device, it may no longer recognize the thermostat. The system will continue to function, but it will always show up in the central manager with an error message,” warns Olsen. Airzone Aidoo Pro control solution These false error reports degrade the overall utility of the central management system, robbing operators of the ability to detect and mitigate problems proactively and requiring onsite testing to diagnose any issues. As VRF systems become the norm for hospitality projects, Verdant needed a solution to reduce the possibility of accidental misconfiguration and improve visibility into system functionality. They called on Olsen to conduct a pilot program, retrofitting sixteen VRF units in the Jacksonville Beach, FL Springhill Suites with the Airzone Aidoo Pro control solution. The Solution For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller The Jacksonville Beach Springhill Suites is a 156-room hotel with a state-of-the-art Daikin VRV rooftop chiller system. The Airzone Aidoo Pro ships preconfigured for the specific HVAC unit model, reducing the possibility for errors during initial installation. For the pilot, the Olsen Group outfitted each VRV unit in the loop with an Aidoo Pro controller. This 1:1 system design simplifies operations and troubleshooting: Any issue can be immediately traced back to a single unit, minimizing the scope and duration or repair downtime. “The Airzone Aidoo Pro offered two key upgrades as a VRV control solution,” says Olsen. “First, the dipswitches are recessed, making them much harder to trip accidentally. Second, Aidoo makes the system much easier to service. We can read error codes, run tests, and diagnose issues remotely, without ever needing to disrupt a guest’s stay.” Airzone’s expansive library This advanced remote management is enabled by Airzone’s expansive library of manufacturer protocols. “Because of our close relationship with HVAC manufacturers, Aidoo Pro can provide the proprietary control signals the central management system is expecting to see,” says Borja Fernandez, Director of OEM Solutions, Airzone. “That preserves all the features of the HVAC unit and thermostat, while also eliminating persistent false error codes. With Aidoo Pro, the central management system can function as a single-pane-of-glass HVAC monitoring and control solution for the building, as intended.” Results and Next Steps The pilot program is expanding to new builds around the globe, including projects in the UK Olsen reports that Springhill Suites is happy with their upgraded VRV system. “They have more visibility into the system and fewer services calls,” says Olsen. “When there is an issue, we can diagnose it remotely for faster resolution and less guest room downtime. It’s a much better customer experience overall.” Verdant is encouraged as well. This pilot program is expanding to several new builds around the globe, including projects in Central America, the Caribbean, the UK, and the EU. HVAC energy savings “There is a massive untapped market for energy-efficient HVAC upgrades in the Caribbean region,” says Olsen. “Energy costs there can exceed a dollar per kilowatt hour. Cost-effective devices like Verdant thermostats and the Airzone Aidoo Pro pay for themselves very easily in that scenario.” Verdant and the Olsen Group have built global brands by helping commercial properties realize significant HVAC energy savings. Through the Airzone Aidoo Pro pilot program, they are continuing to innovate, enabling reliable integration and enterprise-grade control on highly efficient VRF units. “The demand for commercial VRF control is definitely there,” says Olsen. “With Verdant and Airzone, we can deliver it with ease.”

In facilities with high volumes of foot traffic, the constant opening and closing of doors not only lets in chilly air but can cause heating problems for the entire building. Cold drafts bring the temperatures down, so while main rooms benefit from the warmth of the building’s primary heating system, many other areas are left to deal with the arctic side effects. Vestibules, lobbies, entranceways, and hallways are frequently populated, so it’s imperative that facilities hunker down and counteract the cold drafts left behind by those entering and leaving buildings.  Opt for electric ceiling heaters To help neutralize these blustery winds, facilities should consider fan-forced wall heaters that provide continuous comfort through optimized airflow. Such units are ideal for entryways and other spaces where short bursts of heat are needed – providing a tremendous advantage over gentle heating sources that may not be powerful enough to provide the desired amount of warmth. However, if wall and floor space is minimal, facilities can instead opt for electric ceiling heaters. Mounted flat or recessed to the ceiling, these heaters are ideal not only for entryways but also in conference rooms, waiting areas, bathrooms, and lobbies. No matter the case, both products move heated air with a fan to quickly heat the room from the wall or ceiling. Once the heater turns on, the air is moved over a heating element and circulated into the space, making certain that residents are met with warmth and comfort from the time they enter the building until they leave.  Specialized heating units Specialized heating units are designed to stop drafts in their tracks before they laid throughout a building Whether it’s through vents, unsealed windows or cracks and crevices in the building’s foundation, cold air will creep into facilities any way it can. This cool air can make indoor temperatures uncomfortable for occupants and reduce the overall heating efficiency of the facility. Specialized heating units are designed to stop drafts in their tracks before they spread throughout a building.  Fan-forced wall and ceiling heaters with an automatic delay feature eliminate cold drafts on start-up and discharge residual heat from the heater body during the shutdown, helping attack drafts at their source, making the best use of available heat and prolonging the life of the heater. Equipped with integrated thermostats To maintain desirable comfort levels, facilities should consider fan-forced wall or ceiling heaters equipped with integrated thermostats or BMS connections for easy adjustment of room temperatures. A hotel’s vestibule, for example, may experience high amounts of foot traffic during check-in and check-out hours. Because fewer people are coming and going outside of these times, the adjustable thermostat feature allows facilities to alter their heating output needs to ensure heat is not misused and temperatures remain comfortable. For commercial fan-forced wall heaters with striking designs and contemporary looks, Berko® and QMark® offer units to match any room’s décor while supplying an appropriate amount of warmth no matter the time of year. Safety First Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for safety Safety and style go hand-in-hand. While selecting a heater that fits a building’s esthetic is important, opting for a high-quality product that protects against common safety risks should be a top-of-mind priority. Fan-forced wall or ceiling heaters are built with easily accessible power on/off switches for added safety during maintenance. Tamper-proof plugs for thermostat holes prevent unwanted changes to the temperature and keep children and pets from getting into places they shouldn’t.  All fan-forced units also come with thermal overheat protectors that disconnect power in the event of accidental dust or debris blockages to mitigate the risk of injury. Additionally, heaters that include permanently lubricated and enclosed fan motors are shown to have longer lives, require less maintenance and gently administer heat throughout a space. Keep in mind that some heaters are noisier than others, so make sure to choose one powerful enough to negate drafts but quiet enough to prevent disturbances from interrupting daily activities.  Maintaining Warmth and Comfort Drafts bring cold air and a lasting chill into heated spaces every time a door opens, especially during the colder months. To offset the frigidness, consider installing a fan-forced wall or ceiling heater to regain suitable levels of warmth and comfort for all building occupants. Berko and QMark’s commercial fan-forced wall and ceiling heaters provide the strongest, safest sources of heat for those chilly spaces.
