Benefits of a tankless water heater
Tankless water heaters, also known as on-demand water heaters, are quite popular with forward-thinking homeowners, and for good reason. Instead of slowly heating water in a tank and keeping the water in the tank hot, a tankless water heater only heats water that is needed and does so very quickly. Most tankless water heaters produced today are high-efficiency, direct-vent, power vent units. Also, while traditional tank water heaters are all very much alike, the same cannot be said for tankless water heaters.
One obvious benefit to a tankless water heater is its smaller size. Instead of taking up a big chunk of floor space, tankless water heaters get mounted on a wall.
Another huge benefit is an unlimited supply of hot water. You can take a five-hour shower and you’ll never run out of hot water. If you have a hot tub, you could fill the whole thing with hot water and be ready to use it as soon as it’s done filling with water.
Arguably the biggest benefit offered by tankless water heaters is less energy consumption. Because there is no tank of heated water continually having to be kept hot, tankless water heaters don’t experience the same standby energy losses that traditional tank water heaters do.
Tankless water heaters also last longer, with warranties on heat exchangers typically in the 12-15-year range. Power vent water heaters typically come with a 6-year warranty, while traditional tank water heaters typically come with 6, 9, or 12-year warranties.
