The year is 2015 and everything is getting “smart.” From phones to watches to homes, it seems as if nothing is safe from getting a little wiser, and now water heaters are no exception.

Today, heating water can account for up to 30 percent of your home’s energy budget, according to ConsumerReports.org, so it’s no wonder water heater manufacturers are working to boost their products’ efficiency. In fact, some brands now claim their smart water heaters can cut energy costs up to half as much as regular heaters.

Some top brands of conventional water heaters also offer energy-efficient heaters that are “smarter” than average, while other brands focus on the “smart” versions. Here are some of the top brands and products to look for in your search for a smart water heater.
