There are at least five different types of water heaters including storage, tankless, heat pump, solar and condensing.

  • Storage – has an insulated tank to heat and store the water until it’s needed.
  • Tankless – this type is more efficient since it only heats the water with coils when needed.
  • Heat pump – uses less energy because it captures heat from the air to heat the water.
  • Solar – a cell is mounted on the roof to absorb the sun.
  • Condensing – this type is available for 55 gallons or more and can be used if heating with gas.

The two most common types of water heaters are storage and tankless. A typical size for a storage water heater is 40, 50 or 55 gallons. Select the capacity depending on the size of your household and remember to check the first-hour rating. Tankless water heaters don’t store a lot of water so you need to consider the gallons-per-minute rating (GPM). The more people you have in your family, a higher GPM is recommended.


As with any product you purchase, there are various features available on different water heaters. There are anti-scale devices, warranties and digital displays. Understand the available features on different models when comparing water heaters.
