And, to ensure that hot water is always available, AirGenerate units are equipped with electric resistance heating elements that engage when the temperature dips below 20°. AirGenerate water heaters can extract heat from incoming air at temperatures down to 20 degrees – much colder temperatures than other heat pump water heaters. The AirGenerate ATI66DV, on the other hand, truly engages in transferring free heat from air to water because it does not pull air from the interior space. This scenario reduces the energy saving benefits of the heat pump water heater since it effectively works against the home’s heating system. Since the water heater is inside the home, this creates a situation in which a conventional heat pump water heater uses air that has been previously heated by the home’s heating system. ![]() Standard heat pump water heaters, without an air intake duct option, obtain air directly from their surroundings. The cold air is then routed to the exterior of the home via the exhaust duct. Very little energy is used to heat the water, since heat is provided essentially for free from the exterior of the home – even during cooler months.ģ.) Due to the heat exchange, the water stored in the AirGenerate ATI66DV is heated while the air is cooled down. This means the AirGenerate water heater pulls air from outside, and does not draw air from the interior of the home.Ģ.) The AirGenerate ATI66DV extracts the heat from the air and transfers it to the water stored in the AirGenerate water heater tank. ![]() The AirGenerate ATI66DV water heater is the first commercially available heat pump water heater that allows for the installation of an air intake duct as well as an air exhaust duct:ġ.) An air intake duct allows for the installer to connect a duct from the unit to the exterior of the home. AirGenerate direct vented heat pump water heaters carry the promise of minimizing energy use for electric water heating, while providing maximum homeowner comfort. Ecotone Products is a leading distributor of water conserving and energy efficient green building products, and is now stocking advanced engineered AirGenerate ATI66DV direct vented heat pump water heaters. Ecotone Products, LLC continues its path of making the most advanced energy efficient water heating technologies commercially available to home performance contractors, plumbers, HVAC contractors, and utilities.
