![]() ![]() household of close to $350 a year on electricity bills, or $3,750 over the life of a typical HPWH, according to the Department of Energy’s Energy Star consumer website. ![]() The result: savings for the average four-person U.S. In contrast to conventional gas-fired heaters, which generate heat from pollution-spewing combustion, or electric heaters, which use the same type of mechanism found in a toaster, HPWHs use an energy-efficient compressor that gathers heat from the atmosphere and concentrates it in a water storage tank. homes, is even worse: They burn fossil fuels, releasing greenhouse gases and dangerous toxins like nitrogen oxides, which has been linked to numerous respiratory diseases. The impact of gas and propane water heaters, now operating in half of all U.S. Roughly 40 percent of America’s homes are equipped with electric resistance heaters that needlessly draw excessive amounts of energy from the national power grid and contribute to high utility bills. households’ energy consumption-more than cooking and refrigeration combined. Teasing Out the CostsĬurrently, water heaters of all types account for 19 percent of U.S. ![]() “The game changer in this technology is that it is 300 to 400 percent more efficient than conventional heating, using much less energy to provide the same level of service,” Delforge says. Here’s all you need to know to make the switch. 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. ![]() 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, says Pierre Delforge, senior scientist on NRDC’s building decarbonization team. But the day will come when that trusted water heater springs a leak and shuts down permanently-prompting an urgent call to the plumber. ![]()
