A water heater can be one of the biggest energy-hogs in a home, accounting for about 20 percent of your total utility costs. If it’s about time to replace your water heater, the good news is modern high efficiency water heaters can significantly reduce your utility costs.
The tank water heaters most common in U.S. households waste energy by keeping water in the tank at a constant temperature, even when there is no demand for hot water. High efficiency tankless water heaters work differently, heating water only when a hot water tap is turned on inside the house.
With a life span of 20 years or more and an 8 to 34 percent increase in energy efficiency, tankless water heaters are becoming a more attractive option for homeowners looking to replace their inefficient tank water heaters. In homes that use a lot of hot water, two or more tankless water heaters may be necessary to meet demand, and their small size allows for installation inside walls or underneath sinks.
Solar-powered water heaters store water in a tank, but because they use the sun as their power source, these high efficiency water heaters are 50 percent more efficient than water heaters powered by gas or electricity.
In the Midwest, where the weather can change dramatically from one day to the next, solar-powered water heaters are typically installed along with a backup tank system that ensures homes have hot water, even on cloudy days.
High efficiency heat pump water heaters are more common in commercial settings than residences, because they need a lot of open space – about 1,000 square feet, with a ceiling up to 7 feet high. They work by drawing heat out of the surrounding air and transferring it to the water, so they won’t be effective in the winter if they’re inside a cold garage.
Homeowners who purchase a heat pump water heater could save up to $300 a year in electricity costs, as well as qualify for a federal tax credit.
