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, waiting until more hot water is needed. The end result -- hot water that is not limited to what's available in your tank. You always have hot water when you want it for as long as you need it!
Hybrid systems are the new milestone in water heating. The hybrid product combines the best features of tankless and conventional technologies to create an all new category of water heating. Many of the hybrid systems are ideal for families with a high demand for hot water.
