Tankless Water Heaters
Tankless water heaters are compact units that mount on a wall inside your home and supply hot water on demand without end. They work on demand by using sensors and computer boards to monitor the flow of water and change the rate of firing to supply just the amount of hot water required for the current demand. This means that they burn less gas to supply hot water to something like a sink than they would if you are using multiple fixtures at the same time. This modulating firing rate also makes them very efficient to operate as you are only using the exact amount of fuel needed at that time.
