What is your desired temperature? Do you want to get to a comfortable 60-70 degree's or do you have a different application? Take note of that temperature setting it will play a key role in your configuration. This will give you a baseline of worst case or best case scenario if the heaters were off and your space was as cold as the outside temperature. Each state has different outside temperatures during the colder winter months. It's a good idea to view the min clearances of the heater under the manufacturers specifications.Īnother important aspect is the location or the state you live in. If you are too close it might make it too uncomfortable for the people underneath the heater or you can possibly damage the paint or material of your vehicle or machinery. Our Sunstar radiant heaters have recommended mounting height requirements when suspended in a building. Next pay attention to the height of the ceiling. From there you can calculate the square footage by multiplying length times the width.įor example: a 50' x 50' space is 2500 square feet. Take a measurement of the length, width and height of your space. One of the first steps in sizing the right heater is to take a few measurements in your shop. The efficiency of a heater radiant tube distributes heat in a wide area allowing objects in a fab shop, plant or pole barn to absorb more heat. Benefits include: fuels savings of between 30% to 50% in some cases. Heat is retained in the lower working areas of the building making it more efficient and more uniform heating. Infrared heat works from the bottom up, warming people, the floor and machinery first. They come in both propane and gas radiant tube heater options. Tube heaters are long straight or U shaped tubes that carry heat over a long distance, they come in 15, 20, 30, 40 and 50 foot lengths. They are designed to heat large commercial spaces such as: warehouses, auto dealerships, aircraft hangars, farm buildings, garages, shops and open air business’s like car washes. Dust, dirt, and moisture can accumulate on the motor and blower wheel and cause problems. With the negative pressure type heater, the blower is exposed to the air.
You run vent pipe from outside to the box and then exhaust through vent pipe to the outside. The reason is the burner and blower are enclosed in a single housing, so it can be isolated from the ambient air. The positive pressure heater should be used when you have a “dirty” atmosphere, such as in a car wash, wood shop, pool, or spray paint is used. In many applications you can use either type of heater just fine. The negative pressure heater has the blower on the exhaust end and pulls the air into the heater at the burner end. Positive pressure heaters have a blower with the burner and it pushes the air into the tube to the exhaust end.
