Categorizing Water Heaters

Water heaters can be characterized according to two criteria:

  • Presence or absence of a tank
  • Fuel used for power

Most water heaters use either electricity or natural gas for fuel. However, some water heaters can be powered by alternative methods, such as propane gas or even solar power.

Theoretically, a solar-powered water heater may sound like it will save you the most money because it uses an almost endlessly renewable source of energy at virtually no cost. However, many different factors can come into play as you attempt to calculate savings, such as the direction your roof faces and the climate where you live.

Determining Efficiency

Tankless water heaters are often considered more efficient because they heat water up only as it is needed rather than storing water for indeterminate amounts of time. However, a water heater with a storage tank is not necessarily inefficient. Generally speaking, a water heater with a small storage tank may be more efficient than one with a large tank.

Despite requiring a storage tank, an indirect water heater may be one of the most efficient types. Rather than burning fuel to heat the water directly, this type connects to your furnace with a device called a heat exchanger that is filled with fluid. The furnace heats the fluid up, and it circulates through the exchanger to heat the water stored in the tank.
