Houses in the subdivision are 2,000 ft2 (190 m2) each and sell for an average of $230,000. The AirTap A7 water heater has a rated output of 7,000 Btu/hour (7. Installation is fairly easyeven feasible for skilled do-it-yourselfers. The controls on the water heater are set so that the standard element will come on at 100F (38C), while the AirTap is set to heat water to 130F (54C). After selling a few hundred units in late 2007, the company began sourcing the product from an offshore supplier.
If the heat-pump module stops working for some reason, the conventional electric-resistance element will still keep the water warm, but homeowners will notice the problem and contact Skyland Falls.building-materials-china.4 MJ/hour), a first-hour rating of 42.11 but will have a first-hour rating of 60 gallons (230 l).
With todays high energy prices, however, consumers should be more receptive to heat-pump water heaters, according to Harvey Sachs, Ph.com/buy-Heat%255Epump/) water heaters have always been a good idea, but most efforts to design, build, and market them have failed.5 gallons (160 l), a maximum water temperature of 135F (57C), an efficiency of 240% (coefficient of performance of 2.) All this is in a unit that measures only 18" wide by 14" deep by 14" high (460 x 360 x 360 mm), weighs only 48 pounds (22 kg), and sits on top of a standard water heater. Since this is a new system, we wanted a backup, Alexander told EBN. In addition to the AirTap A7 model, AirGenerate is introducing a larger 12,000 Btu/hour model in August 2008, according to Sinha. The first of the new (offshore-manufactured) AirTap units were received in January 2008, and about 200 had been sold through May 2008., the buildings program director at the American Council for an Energy-Efficient Economy. General Electric expects to introduce its Hybrid Electric Water Heater in late 2009. Of 400 units scheduled to arrive in June, almost all were pre-sold by the end of May, according to Sunil Sinha, chief scientist at AirGenerate.
The outsourcing of production will allow the company to significantly ramp up production.com/) in a 100-unit subdivision that is in the works. Skyland Falls is installing the AirTap units on new, 40- and 50-gallon (150 and 190 l) electric water heaters, set up so that the standard electric element provides a backup. According to Alexander, one of his employees can install three AirTap units in a day. This model will offer the same energy factor of 2.11. With some units in place for four months, Skyland Falls has yet to receive a call. Skyland Falls installs the water heaters in utility closets with the outflow air from the AirTap heat pump vented into the adjacent garage; this setup provides some cooling to the garage, which is beneficial in the summer. Having major manufacturers enter the heat-pump water-heater market, according to Sachs, will give this sort of product legitimacy.building-materials-china.
An Affordable Heat-Pump Water-Heater Retrofit The engineers at AirGenerate (previously Beyond Pollution) appear to have done something remarkable: create an affordable, effective, heat-pump water heater that can be retrofit onto a conventional gas or electric water heater, more than doubling the energy performance compared sheet metal fabrication with a standard electric water heater. The economic savings potential is so much greater than before, with the run-up of energy prices, Sachs told EBN. In late spring 2008, the all-electric homes were using less than $2 per day for energy, according to Alexander, though how much of this is for water heating is not known. . (Energy factor is a standardized measure of performance of water heaters; the higher the number, the better. Skyland Falls, a Tennessee developer, has installed 30 AirTap units since January 2008 in a 70-unit subdivision currently under construction. Of the 30 units so far installed, only one unit has had a problema loose bolt that Skyland Falls easily fixed. According to Sachs, a second major player is likely to soon announce another heat-pump water heater.D. The energy factor and first-hour rating of the AirTap are certified by GAMA (previously the Gas Appliance Manufacturers Association and now a broader association of appliance and equipment manufacturers)
