Tankless water heater manufacturer Noritz America has merged the benefits of storage in a standard tank water heater with the efficiency of tankless into one powerful unit, the Hybrid Hot Series. Making its debut at the 2023 AHR Expo, this new hybrid unit provides a continuous hot water supply and quick hot-water recovery with a 10-year warranty.
The Hybrid Hot mounts the Noritz NCC199CDV commercial condensing tankless water heater onto a 119-gallon storage tank. The tankless unit draws cold water from the side port of the attached tank.
Tankless water heater
Once heated within the NCC199CDV to the desired temperature, set between 100°F to 185°F, the heated water travels via a pipe that connects the hot-water outlet at the bottom of the tankless water heater to a port located on the side of the storage tank near the top.
The hybrid unit has a 317 GPH delivery rate and is equivalent to two tankless water heaters
The combination of the storage tank and tankless water heater in the Hybrid Hot Series offers flexibility for indoor commercial applications, such as restaurants and hotels, that require a large dump load of hot water over a short period of time without the use of multiple tankless water heaters. The hybrid unit has a 317 GPH (gallons per hour) delivery rate and is equivalent to two tankless water heaters.
Stainless steel heat exchangers
Faster Hot Water Recovery: The Hybrid Hot Series utilizes a large, stainless steel circulator (Taco 009-FS5) to provide faster hot-water recovery speed. With its high capacity output and direct drive-low power consumption, this larger pump provides a higher BTU input at the quickest rate while offering energy and cost savings. Utilizing this larger pump allows the Hybrid Hot Series to convert cold to hot water in as little as 20 minutes.
Continuous hot water supply: With the NCC199CDV, the Hybrid Hot Series provides limited continuous hot water delivery even after depleting the stored supply. This unit consists of corrosion-resistant dual stainless steel heat exchangers fused together into a single component. It offers a maximum input of 199,900 Btu per hour with a capacity range of 0.29 to 11.1 gallons per minute.
Premature tank failure
This cement is a specifically formulated high-density lining designed to provide maximum protection
Cement-lined storage tank: Cement lining eliminates the need for maintenance, offering energy and cost savings to the customer. Each tank is lined with a minimum of ½-inch thick cement to ensure the protection of the steel tank. This cement is a specifically formulated high-density lining designed to provide maximum protection from the corrosive effects of hot water.
The cement lining is impervious to the adverse effects of the water, preventing the tank from corroding without the need for a sacrificial anode rod. Not requiring an anode rod reduces the maintenance required for end users, as most manufacturers require an annual check of the anode rod. Failure to replace one will result in premature tank failure.
Space-Saving feature
Common venting up to six units: The unit can be common-vented up to six units, offering flexibility with installation and allowing a singular penetration through a side wall or roofline. This space-saving feature comes in handy when space is limited, and multiple Hybrid Hot units are required.
Other features include:
- Direct and Standard Venting: The Hybrid Hot can direct-vent using a 2-inch PVC, CPVC, or polypropylene material with vent lengths of up to 65 feet. In addition, it can be standard-vented using a 3-inch PVC, CPVC, or polypropylene material with vent lengths of up to 150 feet.
- High thermal efficiency rating: The unit has a 98% thermal efficiency rating with a 0.96 UEF.
