According to the Energy Information Administration, water heaters can account for 19% of the typical homeowner’s utility bill. In newer, high-performance homes they account for 21% to 32% of the homeowner’s bill because newer homes themselves take less energy to heat and cool, thus water heating takes a relatively larger percentage of the bill. To reduce the amount of energy needed for water heating, builder can install high-efficiency electric or gas water heaters or consider alternative efficient technologies like tankless gas heaters, solar thermal water heaters, or air-source heat-pump water heaters.
