What’s the Most Energy-Efficient Water Heater?
The unfortunate day will come when that trusted water heater springs a leak and shuts down permanently, prompting an urgent call to the plumber. What will you do? Buy the same old water heater they used fifty years ago?
The technological advances and increasing energy efficiency found in the new generation of environmentally friendly heat pump water heaters (HPWH) make them a worthy investment for anyone looking to reduce both carbon emissions and utility bills at once.
HPWHs, which produce heat using the same technology that refrigerators employ to stay cold, release no emissions and get the job done on as little as one-half to a third of the energy of a conventional electric resistance or gas heater. This technology is 300 to 400 percent more efficient than conventional heating, using way less energy to provide the same type of service. HPWHs use an energy-efficient compressor that gathers heat from the atmosphere and concentrates it in a water storage tank.
