Conventional Storage Water Heaters
Conventional storage water heaters remain the most popular type of water heating system for the home. A single-family storage water heater offers a ready reservoirfrom 20 to 80 gallonsof hot water. It operates by releasing hot water from the top of the tank when you turn on the hot water tap. To replace that hot water, cold water enters the bottom of the tank, ensuring that the tank is always full. Conventional storage water heater fuel sources include natural gas, propane, fuel oil, and electricity.
Tankless Water Heaters
Tankless water heaters provide hot water only as it is needed. They don’t produce the standby energy losses associated with storage water heaters, which can save you money. Demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. You don’t need to wait for a storage tank to fill up with enough hot water.
Heat Pump Water Heaters
Most homeowners who have heat pumps use them to heat and cool their homes. But a heat pump also can be used to heat watereither as stand-alone water heating system, or as combination water heating and space conditioning system. Heat pump water heaters use electricity to move heat from one place to another instead of generating heat directly. Therefore, they can be two to three times more energy efficient than conventional electric resistance water heaters.
Tankless Coil/Indirect Water Heaters
Tankless coil and indirect water heaters use a home’s space heating system to heat water. They’re part of what’s called integrated or combination water and space heating systems. A tankless coil water heater uses a heating coil or heat exchanger installed in a main furnace or boiler. Whenever a hot water faucet is turned on, the water flows through the heat exchanger. These water heaters provide hot water on demand without a tank, like a demand water heater, but because they rely on the furnace or boiler to heat the water directly, tankless coil water heaters work most efficiently during cold months when the heating system is used regularly.
