Get Optimal Performance from a Tankless Water Heater
September 4, 2009 By Willem Maas
Tankless water heaters have caught the eye of many homeowners lately—as a way to reduce the 19 percent of total home energy use consumed by water heating. According to research sponsored by the National Renewable Energy Laboratory (NREL), heating water with a tankless system is 12 to 34 percent more energy efficient than using a conventional storage tank system. And when tankless systems are installed at each water outlet, gains in efficiency can range from 28 to 50 percent.
Others are impressed by the ability of tankless systems to deliver hot water “endlessly” in a busy household, as well as the space saved because a storage tank is no longer needed.
These factors, combined with rising energy bills, a federal tax credit for 30 percent of the total cost (up to $1,500, including installation), and greater availability, make tankless a technology well worth considering.
