Furnaces

Choose from a variety of furnaces, fireplaces, and accessories from Suburban, Furrion, and Dometic! Each furnace comes with either a 1-Year parts warranty with The RV Surplus or the standard 2-year manufacturer warranty. Refer to the description of each product for exact details of which warranty. These can be used to heat any RV or Trailer. All units include vent pipes and manual.

If you're replacing an Atwood furnace, the closest replacement will almost always be a Dometic furnace. It is possible to switch to a Suburban in some cases. Suburban units will typically be 1" wider and have a larger cutout for the vents if you are not using a door. 

For ice fishing and small trailers, we recommend the NT-20SEQ. For your RV, multiply your length by 1000 to get the recommended BTUs for your camper.

Furnace parts can be found in our Appliance Parts section.
