Non Separated Combustion Heaters

Non-Separated Unit Heaters pull the combustion air straight from the room that it’s heating. These units are typically used in standard shops/garages and are less expensive. However, if your room has a harsh atmosphere with chemicals, high humidity, or negative pressure, you should purchase a Separated Unit Heater, which pulls air from outside the heating room. If you have questions or need helping picking out the right heater, please give us a call or chat with us online.
