Types of water heaters

There are several types of heaters currently available in the market today. However, these can be broadly classified into five types.

A conventional storage water heater uses a storage tank for hot water, while a tankless or demand-type water heats the water directly and does not require the use of a storage tank. Heat pump heaters, on the other hand, move heated water from one location to another. Solar heaters utilize the sun’s heat to create hot water while tankless coil and
indirect heaters generate hot water using a home’s space heating system.

Water heater fuel types

Water heaters can be powered by different fuel types. Among the most commonly used are electricity, fuel, geothermal energy, natural gas, propane and solar energy.
Electricity is commonly used for conventional storage, tankless, heat pump, tankless coil and indirect water heaters.

Oil is used as a fuel for conventional, indirect combination and space heating water heaters.

Geothermal energy may be used as a fuel source after the installation of a geothermal heat pump system in the house. Natural gas and propane are often used with conventional, tankless, combination and space heating water heaters. Solar energy is used exclusively for solar water heaters.
