An indirect-fired propane heater is a common choice for climate control on construction sites, outdoor events, and other spaces requiring temporary heat. The heater can be installed for temporary use indoors or outdoors. If installed indoor, the flue must be vented to the outdoors by an HVAC professional. Additionally, the heater can be recirculated to boost performance in cold weather environments. It is capable of temporarily heating 3,500-6,500 square feet with standard 8′ ceiling height, depending on factors such as building envelope, air handling units for air distribution, and other factors.

The 400,000 Btu Pro Series is indirect-fired, meaning there is no exposed flame or fumes to be concerned about. You can be assured that fresh, clean air will be delivered into the structure without the fear and concern of flames shooting out of the front of the heater. To further ensure safety, all heaters come standard with an on/off thermostat, which means you do not have to manually adjust the gas flow to control the temperature. The 200,000 Btu Pro Series control box has a supply voltage display to avoid faulty power sources. There are redundant safeties built-in to the heater, including high-temperature limit switch, airflow switch, and flame detection photocell. The body of the heater is made of heavy gauge steel, protecting the components of the heater, and surrounded by steel arms for securing the heater during transport, further safeguarding the heater from accidental damage. The heater has a 4 wheel design providing superior maneuverability.
