Water heaters are designed to heat water for washing dishes and clothes, as well as making your water hot enough for you to bathe. While different varieties of water heaters exist, they all serve the same function.

Types

According to the Home Depot, most water heaters are fueled by either electricity or natural gas. Gas water heaters typically cost more than electric heaters but cost less to operate. Meanwhile, electric water heaters cost less to buy and require less maintenance, but will cost more in utility bills over time.

Water Heating Tanks

Traditional water heaters are designed so there is a tank that is constantly full of hot water ready for use. These models are made to cover all the points in your house that require hot water. However, if you need additional heating or just want to heat one faucet, you can buy individual units that fit under the sink.

Tankless Water Heaters

Tankless water heaters provide an alternative way to heat water. Rather than store the water, these types heat water by running it through hot coils. Tankless water heaters are more energy efficient and take up less space than the traditional model, but cost more to buy.
