The Mechanics Behind Unit Heaters

The Mechanics Behind Unit Heaters

The process begins with the outdoor wood boiler heating water to a high temperature. This hot water is then circulated through pipes leading to the unit heater, strategically placed inside the garage, barn, or workshop that requires heating.

The unit heater contains a heat exchanger—a series of coils or panels through which the hot water from the wood boiler flows. As the water passes through, its heat is transferred to the metal surfaces of the exchanger. Then, the unit heater's fan kicks into action, blowing warm air across these hot surfaces. This air absorbs the heat and is propelled out into the room, raising the ambient temperature to a comfortable level.

A unit heater is controlled by a thermostat that turns on when the room needs heat. When the thermostat senses the need for heat, it turns on the fan motor; the fan blows air over the finned heat exchanger which warms the flowing air and raises the air temperature in the room.

Lastly, these heaters come in various sizes and types, allowing you to choose one that best fits your space’s specific heating needs.
