Introduction to Tankless Water Heaters

Tankless, on-demand, instantaneous, or inline are just different names to refer to a water heater that produces hot water quickly, and without a tank. Most people in the United States use a glass-lined water heater that keeps water hot 24 hours a day, even while you're at work or sleeping. A tankless hot water heating system does not store hot water and heats the water as you use it.

Tankless water heaters come in both electric and gas units in many capacities. Usually they can produce about 2-5 gallons of hot water per minute. If you decide to buy a unit, you will need to know how to select the right tankless water heater.

Before deciding on a tankless water heater, consider benefits and challenges.

Benefits:

• Constant supply of hot water; there is no tank that empties
• Uses energy only when hot water is demanded
• Lower energy costs
• Designed to last more than 5 times the lifespan of a hot water tank
• Smaller than tank units, saving floor space

Challenges:

• Must size the unit correctly to avoid losing hot water
• Smaller units may not be able to supply enough water for a household
• May need more than one unit to heat water for more than one shower
• More expensive than tank units
• May need to limit the flow of water to properly heat water (for example, to fill a tub)
• Existing gas and water lines may need to be increased in size

Did you know? The average American household spends about 13% of their utility bill on heating hot water alone.
