Choosing a Tankless Water Heater
Tankless Water Heaters, also called Instantaneous or Demand Water Heaters, provide hot water only when it is needed instead of being on a cycle that keeps the water continuously hot for use when needed. Traditional storage water heaters produce standby energy loss that costs homeowners a substantial amount of money every year.
Like the name implies, tankless water heaters heat the 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.
In an electric tankless water heater, an electric element heats the water. In a gas unit, a gas burner heats the water. They provide a constant supply of hot water and you don’t need to wait for storage tank to fill up with enough hot water, causing you to “wait for the water to heat up”. You also don’t “run out of water” during extended usage.
Tankless water heaters usually supply 2 - 5 gallons of hot water a minute. Typically, gas water heaters will produce higher flow rates than electric ones. For homes that use 41 gallons or less of hot water daily, tankless water heaters can be 24% - 34% more energy efficient than conventional storage tank water heaters. This saves on water, because you aren’t wasting it while waiting for it to warm up, it also saves on the energy it takes to keep the supply of water hot even if you aren’t using it.
