According to the Department of Energy, 15 to 25 percent of home energy costs come from water heating. There are more than 400 models of propane tankless and storage tank Energy Star water heaters. Propane water heaters cost up to 50 percent less to operate and can save up to one ton of greenhouse gas emissions each year compared with standard electric storage tank water heaters. And, as more efficient water heater technology becomes the new norm, it's a better time than ever for homeowners to consider what kind of water heater is best for their home.
In 2015, the Department of Energy raised the bar for water heaters. As the new National Appliance Energy Conservation Act regulations go into effect, new water heaters will be required to meet a higher efficiency rating. Watch the video below to learn what this change means for homeowners.
