Using a Tankless Water Heater As a Boiler: Efficiency Unleashed

Using a tankless water heater as a boiler is possible but not recommended. It is not designed for space heating.

A tankless water heater heats water on demand, providing hot water instantly. Unlike traditional boilers, it doesn’t store hot water, making it less efficient for heating large spaces. Although some people consider using tankless water heaters as boilers, they are primarily designed for providing hot water for showers, sinks, and appliances.

Using them as a boiler can lead to inefficiencies and potential system failures. For optimal performance and longevity, it’s best to use equipment specifically designed for heating your home. Investing in a proper boiler ensures reliable and efficient heating, making your living space comfortable and warm.
