Direct Fired Heaters

Efficient Vapor Propane or Natural Gas Heating

Benefits of Direct Fire Heating

Direct fired heaters are very much like your typical gas grill or stove top, in which a propane tank or other type of natural gas forces air directly through a flame to heat the air. Direct fired heaters are a great addition to any outdoor party in the fall, winter or early spring, as well as construction sites or disaster relief. What are some of the benefits to direct fire heaters? Here are just a few:

Efficient

First off, the main benefit to using a direct fire heater is the efficiency it provides. As a fuel heater, they convert 100 percent of the fuel being used to heat which lowers fuel consumption and operating costs. This is great if you’re using a heater all day long at a construction site and are trying to keep energy costs down.

Powerful

High amounts of heat (BTU’s) are produced in smaller units when compared to indirect fire heaters. OnSite provides heaters that supply 400,000 BTU’s all the way up to 4,000,000 BTU’s. Now that is power!

Easy to Move

Because they are on wheels and portable, direct fired heaters are pretty easy to set up, move around and turn off when heat is not needed. All it takes is some simple knowledge and common sense to use one of these types of heaters. A few of OnSite’s heaters are also small enough to be moved by one person, requiring less manpower to get heat where you need it.

Lower Energy Cost

Direct fired heaters are lower cost than other types of heaters, meaning you can pump out heat all day long without compromising your budget. If you’re looking for a cost-effective way to boost the temperature in your job site, business or work area, direct fired heaters are the way to go.

Safe for Everyone

Numerous safety features give power to the user, allowing the heaters to stay running without oversight. If you’re throwing a party outdoors, or working a construction site during the winter, the last thing you need to worry about is heater upkeep. With direct fired heaters, even the most novice user can have steady heat flowing all day long.

Lower Maintenance Costs

Unlike indirect fired heaters, direct fired heaters are easy to maintain and a simple way to provide heat. Because all it takes is a full propane tank, many times if your heat runs out, the only thing you need is more gas. A quick stop at the gas station or hardware store to refill your tank is all the maintenance that’s required on most direct heater models.

Built in Thermostat

On many direct heater models, a thermostat is displayed to inform the user on what the temperature is. This helps control the climate and temperature, giving the worker the option to turn it off when the temperature reaches the perfect point.
