An add-on accessory for the Navien NPE-A Series tankless water heater that creates a high efficiency space heating and endless domestic hot water system
Designed for both retrofit and new construction residential applications, Navien’s H2Air Kit* allows for space heating and DHW system integration between NPE-A Series tankless water heater models and a hydronic air handler. With H2Air you will have a combination appliance that can provide endless domestic hot water and continuous space heating when sized correctly.
H2Air is compatible with hydronic air handler models that require W1/W2/R terminals along with single or dual-stage thermostats†. The included Outdoor Reset Sensor provides optimum performance and efficiency for space heating.
Note: H2Air is for use with one NPE-A and one AHU only. For detailed information, refer to the AHU manufacturer’s literature to determine the proper output capacity.
