Understanding Graphical User Interface
The boiler’s straightforward and user-friendly design makes installation easy for contractors
For the homeowner who seeks heating comfort while maintaining low utility bills and a reduced carbon footprint, the Evergreen stainless steel condensing boiler features an AFUE rating of 95 percent and is designated as Most Efficient by ENERGY STAR®, a distinction that recognizes highly efficient products. The boiler’s straightforward and user-friendly design makes installation easy for contractors.
The unit features a guided setup wizard, an easy to understand graphical user interface, simple controls and 10 heating system presets for quick setup. The recently expanded Evergreen line is now available in six sizes, ranging from 70 to 399 MBH input, accommodating both small and large residential projects, as well as light commercial applications. The units are adaptable for most heating demands, ensuring heating comfort through multiple zones.
Maintaining High Efficiency
For the residential and light commercial customer who requires a multiple boiler setup, the Evergreen line can cascade two to eight boilers together, and ZoneStacking® up to 24 programmable zones with no external panel required. With this advanced control feature, the Evergreen boiler maintains optimal efficiency through lead-lag rotation and balanced heat loading.
The nanotechnology coating repels exhaust residue formation on the heat exchanger surface
The new Ultra Series 4 boilers feature a state-of-the-art heat exchanger with nanotechnology coating that works like Ultra Armor, protecting the unit from buildup in the heat exchanger while maintaining high efficiency. The nanotechnology coating repels exhaust residue formation on the heat exchanger surface while preventing acidic condensation penetration, ensuring the unit requires no cleaning for a full five years after installation.
Light Commercial Applications
Available in six sizes, the Ultra Series 4 offers quiet operation, ease of set up and control, and unmatched comfort with the potential to provide immediate payback in energy savings – making it an ideal choice for single-family residences. The Ultra Series 4 also is a good fit for light commercial applications, allowing contractors to pair boilers in sequence to heat larger buildings and control multiple boilers from a single control panel.
The GV90+ high efficiency cast iron boiler line is designed for homeowners who seek the right balance between ideal heating comfort, low utility bills, reliability and product longevity. The unit features streamlined controls with a simple setup, and a low maintenance, durable design. The GV90+ offers an AFUE rating of 91 percent, exceeding ENERGY STAR® program requirements, and available in four convenient sizes.
Primary Heat Exchanger
The GV90+ is designed with a high performance durable cast iron primary heat exchanger
The GV90+ is designed with a high performance durable cast iron primary heat exchanger. A corrosion resistant stainless steel condensing secondary heat exchanger recoups heat energy from exhaust normally wasted, to further increase system efficiency. This unique, durable unit easily adapts to satisfy various comfort heating demands, from multiple in-home zones to driveway snow melting and even pool heating. Unlike most traditional cast iron boilers, the GV90+ line allows easy integration of outdoor reset to take advantage of low water temperatures and improve overall system energy cost savings.
The new AquaBalance Series 2 units feature an energy efficiency of 95 percent and combine the warmth of high-efficiency space heating with the convenience of on-demand domestic hot water in a reliable, space-saving, easy-to-install package. AquaBalance boilers are ideal for retrofits or new construction in single-family homes, apartments or condominiums.
Titanium-Infused Heat Exchanger Technology
Now available in three sizes (80, 120 and 155 MBH input) in both combi or heat-only versions, the units feature an aesthetically pleasing design and simple, user-friendly controls, while delivering contractors and homeowners easy installation and worry-free operation.
With the industry’s latest stainless steel, titanium-infused heat exchanger technology, the AquaBalance Series 2 provides advanced condensing technology to deliver efficient space heat and domestic hot water in a sleek, compact design that can fit in a closet. The AquaBalance Series 2 boilers were awarded the ENERGY STAR® Most Efficient designation to deliver maximum operational cost savings to homeowners.
