Heat Pump retrofit triples the energy efficiency of your water heater
Posted by sritchie, 4:20 pm
Air Tap is a hot water heater retrofit heat pump. It cuts your hot water heating energy consumption by 70%, and only costs $700, so the typical family of 4 will recoup costs in less than 2 years.
Heat pumps use the latent energy from the air to heat the water, and are inherently 2-5 times more efficient than other methods of heating. It works well in the Seattle climate since our temperatures are pretty mild year round.
Pretty cool.
