A large tank water heater is an everyday commodity in most U.S. households, but with more demand for tankless water heaters, the tanks could become a thing of the past. The name basically speaks for itself, and without needing to constantly heat a large tank of water, the tankless heaters are more efficient.
â??As soon as you turn on a faucet, it'll automatically turn on the water heater,â?? said Universal Plumbing and Heating mechanic, Mark Spencer. â??Then based on how many faucets are on, the water heater will fire heat based on that. The more faucets, the more flow, the more heat, the more gallons you get.â??
Tankless water heaters are ideal for large families, who may be used to running out of hot water after a few showers as a result of an empty tank. But the tankless heater is known as a demand heater, so however much water is needed, that's what'll be heated. Tankless heaters generally cost more, anywhere from several hundred dollars for an electric model, to several thousand for a gas model, but mechanics say in the long run, it could save you more.
â??You're average tank water heater might be at best 70 percent efficient to 80 percent efficient, where a tankless water heater probably starts at the high 80's to 97 percent efficient,â?? Spencer said. â??There are a lot of people that love them because they can save a lot of money on their energy costs, almost half.â??
Spencer also mentioned that water type is important when considering tankless. Hard water is not compatible with the tankless water heater, unless you have a water softener. Make sure to get your water tested first to see if a tankless water heater is a better option for your family.
