Tankless or demand-type water heaters heat water directly without the use of a storage tank. Heat pump water heaters move heat from one place to another instead of generating heat directly for providing hot water. Solar water heaters use the sun's heat to provide hot water.
We know that purchasing a water heater requires a lot of thought. The Home Depot can help you select the best water heater for your needs whether you are interested in professional installation or installing it yourself. Start by determining if a tankless water heater or a tank water heater is a better fit for your household. For tankless water heaters, determine how much water your home needs and the ground water temperature in your area to help you decide what unit is right for you.
