Indirect Fired Heater Rentals
OnSite HVAC has a variety of indirect fired heating systems for commercial or industrial rental.
Our indirect fired heating systems won’t add any moisture to the air, and are perfect for enclosed, tightly-sealed spaces with no windows or doors.
Get in touch today so we can recommend the right solution for your space.

Indirect fired heater rentals are the only choice for when you are in an enclosed area that is tightly sealed, with no windows or doors opening to outside fresh air. These function identically to your home furnace with chimney. Only fresh air will come out of the vents while the combustion by-products are forced outside. Our promise to you is to never leave you with equipment that you don’t know how to operate. We are available 24/7/365 so you never experience down time.
Indirect fired heater rentals will not add moisture to the air. They will only provide you with fresh, clean, dry air just like in your home. They can be used in businesses that require temporary heat, office spaces, assisted living facilities, tents, or event functions. Corded thermostats are included with most indirect fired heater rentals as well as ductwork. Most are sitting on wheels making portability to other locations simple.
We provide:
- Full service installation and start-up consulting
- Propane fuel delivery and set up
- Diesel fuel delivery and set up
- Fuel container rentals
- Equipment monitoring
There is no job too big or too small for us. Our promise to you is to never leave you will equipment that you don’t know how to operate.
