The first tankless water heater that James covers is the NRCR (Noritz residential condensing recirculation). The NRCR provides unlimited, instantaneous hot water with its built-in recirculation pump. That sort of technology eliminates the need for installers to put in their own recirculation pumps to use with the tankless technology, so it reduces jobsite labor. Every component is designed for service and can be maintained or repaired with tools in most HVAC technicians’ tool bags. The NRCR is designed to be serviceable for its entire lifespan, comes with a 15-year warranty, and boasts an efficiency rate of 98%.
Noritz also offers a combi boiler, the NRCB (Noritz residential combi boiler). The NRCB is a wall-hung combination boiler that can provide domestic hot water AND space heating out of a single appliance. It is also 95% efficient. A 35,000 sq ft 3-bathroom home can generally rely on just one NRCB for all of its hot water and space heating needs. As with the NRCR, the NRCB is designed to be easily serviceable.
Noritz also has the EZ series, which works well for retrofit applications because it has plumbing connections up top. The EZ series units are also 98% efficient.
On the commercial side, Noritz offers the NCC199CDV, which is its flagship commercial tankless water heater. It is possible to meet high water heating demands by cascading multiple water heaters with the NCC199CDV as the main tankless engine. The NCC199CDV also has a 10-year commercial warranty.
Noritz also has hybrid solutions in its product lineup. The Hybrid Hot product attaches to a current tank, which recovers tank water and takes stress off the tank, which reduces the likelihood of leaks and may increase longevity.
The total tankless solution comes with the TTS Synergy series. It comes in configurations ranging from 2 to 6 units for high-level installations. The TTS Synergy units have one point of connection with the facility, and the configuration can control the facility’s power, water, gas, condensate, and building recirculation with that single point of connection. The system uses an ECM (which modulates for maximum efficiency) and also acts as a storage unit for the water.
