Tankless Water Heaters
Tankless water heaters are a marvelous new appliance. Traditional water heaters have to continuously work to keep water hot inside the tank. This wastes a lot of energy because you are heating water even when you are sleeping. Tankless water heaters only heat water when you turn the hot knob.
Water is forced through a small outlet where it is super heated at what ever temperature you choose. You also never run out of hot water!
