5 Reasons to Use Indirect Fired Heaters on Your Job Site

On Site Companies VG 400 Indirect Fired Heater

While the weather gets colder, you may be wondering what the best way to heat your work site will be. Heating you site will allow your workers to feel more comfortable, which will in turn allow them to achieve more throughout the day. If you are building an enclosed structure, then Indirect Fired Heaters may be the solution that you are looking for. Here are five reasons that may lead you to choose Indirect Fired Heaters for your job site this season.

1.)  No Unwanted Moisture For your past construction sites you have been using open-flame Direct Fired Heaters, which deliver heat into structures. These heaters convert 100% of fuel into heat, which seems like the most fuel efficient and cheap way to heat your job site. The downside to this equipment, however, moisture can become a hindrance to your work. According to Ken Cannella, product manager for Wacker Neuson Climate Technology, “ Every 100,000 BTUs of fuel burned with a direct-fired heater results in one gallon of water as a byproduct.”  Unwanted moisture and condensation on you job site can cause setbacks, property damage and loss of productivity that you just can’t afford. Using Indirect Fired Heaters will not produce any unwanted moisture that can seep into your job site. These heaters will only produce clean burning heat to be pumped into your location.

2.)  Ventilation Flue All Indirect Fired Heaters come standard with a ventilation flue that allows you to safely vent all noxious fumes away from the job site. Because of this standard flue, these heaters can safely be placed inside or outside of your job site.

3.)  Enclosed Flame If you have to worry about debris around your site coming into contact with your heating equipment, then our Indirect Fired Heating line is the safest solution.  On standard Direct Fired flame heaters you have an exposed flame that may be susceptible to foreign objects entering the flame or flammable objects being placed too close to the heater and igniting.  With the enclosed flame of Indirect Fired Heaters, you can be sure that nothing will enter the flame, and you will only get clean burning heat into your structure.

4.)  Ductable We all know that certain job sites will inadvertently heat unevenly.  This could cause your workforce to be uncomfortable, and also may force you to provide several heaters to different areas. Indirect Fired Heaters provide efficient heat delivery to you job site to make sure that you can use the least amount of fuel possible. All of our Indirect Fired Heaters can be ducted to provide heat evenly throughout your job site.

5.)  Remote Thermostat Technology Our On Site Indirect Fired Heaters can be equipped with remote thermostat technology that can alter you to any issues that the heater is having, and also keep your area at the optimal temperature at all times.  You can monitor the performance of your equipment from your mobile device, and our technicians will also be alerted if there are any problems with the equipment.
