Saving Energy with a Tankless Hot Water Heater
A tankless hot water heater has many energy saving benefits that make it an excellent choice for the modern home, and a superior alternative to conventional units.
Water Heating Costs
A home’s energy consumption usually comprises 20% water heating, for various purposes including laundry, cooking, washing dishes, and bathing. Up to $500 annually can be spent on this alone. A tankless hot water heater can reduce energy costs exponentially.
Conventional Water Heater (Tank Based): How it Works
Water heaters that use a tank heat water and maintain its temperature, regardless of whether hot water is drawn from the tank. When the unit is not being used, it suffers from an issue known as “standby loss.” This is a term which refers to the energy lost by water in the tank being maintained to a certain temperature—even during long periods of little or no use of the hot water.
Standby loss is responsible for around 20% of a home’s water heating costs annually. That means that nearly a quarter of a household’s entire annual water heating costs are literally wasted.
Tankless Hot Water Heater: How it Works
A tankless hot water heater heats water “on demand,” as hot water is needed. When the faucet is opened, a sensor detects the water flow and activates the heating coils or heat exchanger. As water flows through the tankless hot, it is heated (in about 5 seconds) to the temperature that is desired. After the faucet is closed, the sensor in the tankless hot water heater detects the lack of water flow and the heating coils are automatically shut down.
Advantages of Using a Tankless Hot Water Heater
Since there is no standby loss, a tankless hot water heater is far superior to a traditional unit. Water is not wasted as a result of the immediate heating that takes place. The hot water does not “run out” with a tankless hot water heater, as it would with a tank-based system. It can also last up to 20 times longer since water is not stored in the system. Tax credits may also be available for those who own and use a tankless heater.
