The Science Behind Masonry Heaters: Storing And Radiating Heat With Thermal Mass
The design and functionality of masonry heaters revolve around the concept of thermal mass. This principle allows the masonry to absorb and store an enormous amount of heat, gradually releasing it into the living space for an extended period.
When a fire is ignited within the masonry heater, the initial heat generated is absorbed by the surrounding masonry. As the fire continues to burn, the heat radiates into the room, providing a comfortable and consistent warmth.
The thermal mass of a masonry heater is responsible for its remarkable efficiency. Unlike conventional wood stoves that rapidly lose heat through the chimney, masonry heaters are designed to circulate hot flue exhaust through baffles. This process heats the surrounding masonry, reducing the temperature of the chimney exhaust and maximizing the heat transfer to the living space.
By utilizing the properties of thermal mass, masonry heaters are able to provide a steady and efficient source of heat for extended periods.
