How It Works

When opening a hot water tap or starting the dishwasher, the tankless water heater recognizes the need for hot water and starts the heating process. The temperature of the incoming water is used to calculate how much heat the burners must produce to deliver water at the desired temperature. When the demand for hot water ceases the unit shuts down and uses no energy while waiting until more hot water is needed. For commercial options check out our commercial HVAC page.
