Heat-Pump Water Heaters
A new breed of water heater uses time-proven heat-pump technology to cut energy consumption in half.
Synopsis: Although heat-pump water heaters have been around for 25 years, they’ve caught interest in the past few years as energy prices have spiked and as a number of manufacturers have introduced integrated appliances (as opposed to the retrofit units that made up the market previously). Heat-pump water heaters create hot water from warm indoor air and are fueled by either electricity or natural gas. The heat pump warms water in a storage tank by compressing and expanding refrigerant in a closed loop. As by-products, the heat-pump water heater generates cool, dry air and condensate. While heat-pump water heaters can be expensive, the cost can be minimized through federal tax credits and reduced energy consumption.
Heat-pump water heaters have been around for about 25 years, but I didn’t know they existed until energy costs spiked a few years ago. The relatively low cost of energy over the past 30 years…
