Conventional water heaters are a common fixture in most household basements. Their purpose is simple: to constantly store a tank of hot water “on standby” so that users can receive hot water shortly after turning a hot water valve on in the house. To keep this supply of water hot, however, conventional water heaters consume energy and heat that is lost through the walls of the storage tank. In addition, conventional water heaters often experience a lag time between when the valve is turned on and when the hot water arrives at the faucet, sending unused cold water (and your money) down the drain.


A tankless or “demand” water heater, however, only heats water when a hot water valve is in use, saving 20% to 30% of energy consumption. Tankless water heaters are activated by the flow of a hot water valve and instantly heat the water as it is being used. Other benefits of using a tankless water heater are its easily replaceable parts, variety of sizes for different faucet applications and power source options (propane, natural gas or electricity). Tankless heaters save energy that is typically used to store hot water on standby and they conserve water that goes unused while water is heating up. With both energy and water savings, a tankless water heater will pay back installation costs in one to five years.
