Tankless water heaters have been a feature on the European market for several decades, where they’re known as instantaneous water heaters, but they’re a relatively new innovation on the U.S. mass market.
Making an informed decision between tankless and traditional water heaters means comparing pros and cons. Here are a few things to bear in mind:
- Delivery — Traditional water heaters can only supply a volume of water that’s limited by the size of the tank. Typically a household tank holds 50 gallons or less, and an average bathtub takes 37 gallons to fill. With a tank system, once the hot water is gone, it’s gone. Until the heating elements bring another tank-full up to temperature, no one can have a shower or run the dishwasher or clean their hands. A tankless system delivers an infinite volume of hot water, only on demand.
- Economy — With a tankless system, there’s no waste. Because hot water is not stored and waiting to be used, the heat you pay for is delivered immediately, not lost to the atmosphere. Lost heat translated directly into wasted money.
- Space — Water tanks take up a great deal of space; they typically occupy an entire closet. A tankless water heater is smaller in comparison and is attached to the wall in a convenient location. Access and airflow must not be blocked, but otherwise you won’t even know it’s there. The entire area where the old tank once stood is freed up, and who couldn’t use more storage space?
The government’s tax credit incentive for the installation of tankless water heaters expired at the end of 2011, but their energy-efficient performance still makes them worth considering.
