More Heat for Bigger Spaces, Same Clean, Quiet Propane Comfort
Supported by our local Fort Collins, Colorado team. The Propex HeatSource HS2800 is the bigger brother to the HS2000, an interior-mounted propane air heater that delivers 9,500 BTU of clean, dry heat. That extra output is designed for larger camper spaces like Sprinter, Promaster, and Transit vans, bigger trailers, and builds that see colder climates. Set the Digistat thermostat and keep camping through cold nights and shoulder seasons without diesel smell, fuel gelling, or combustion gases in your cabin air.
It is a strong fit for RVs, trailers, tiny homes, semis, boats, and other builds where you want permanent, quiet propane heat with headroom to spare. Heating a smaller space? The HS2000 (6,500 BTU) uses the same interior-mount design.
Why Choose Propane Over Diesel?
Diesel heaters have their place, but propane is often the better fit for van and trailer heat. Propane is a clean, convenient fuel source without the diesel fuel-gelling concerns that can complicate winter operation, and Propex keeps combustion sealed off from the air you breathe.
- Less fuel odor: Propane provides little to no fuel smell compared with diesel-fueled heaters.
- Cold-weather friendly: Propane does not have the diesel gelling issue that can complicate winter operation.
- High-elevation capable: Choose the High Altitude option for reliable combustion around 9,000-11,000 ft. It also runs well at sea level.
- Quiet and dependable: Integrated electronics and self-diagnostic safety controls keep the system steady once installed.
- Dry heat: Sealed combustion delivers dry heat without adding moisture from burner exhaust inside the living space.
- More output, same footprint style: 9,500 BTU from a compact interior mount for spaces that outgrow 6,500 BTU.
Warm, Dry Heat Without Combustion Inside
The HS2800 mounts inside the living space. Heated cabin air recirculates through the heater while the combustion process stays separate from the air you breathe.
Propex uses a closed-loop forced-air heating system. Cabin air is circulated through the heater, warmed, and returned to the same space. Fresh combustion air is drawn from outside through dedicated pipes, and exhaust gases, including carbon monoxide, are directed outside when installed to Propex requirements.
| Heater location | Interior mount |
| Heated air | Recirculated from the cabin through the heater and back inside |
| Combustion air | Drawn from outside |
| Exhaust | Directed outside when installed to Propex requirements |
| Heat type | Forced-air propane heat |
| Thermostat | Digital Digistat included |
What's in the Kit?
- Propex HS2800 heater unit
- Digital Digistat thermostat
- Installation hardware, ducting, wiring, and combustion pipes
Best for
- Larger vans like Sprinter, Promaster, and Transit builds
- Bigger trailers, RVs, tiny homes, semis, and boats that need more than 6,500 BTU
- Cold-climate and winter campers who want extra heating headroom
- Buyers who want a fixed install with Digistat control and modest 12V draw
- Regular camping above about 7,500 ft (choose the High Altitude option)
Not the right fit if
- You cannot spare any interior space for a furnace mount (this heater is interior-mounted)
- Your space is small enough that 6,500 BTU will do the job (look at the HS2000)
- You need a portable heater with no permanent install (look at the PS2000 Slimline or PS2000 Portable Heater System)
Compare Propex Heaters at Mountain Time Campers
| Model | Heat output | Mount | Best for |
|---|---|---|---|
| Propex HS2000 | 6,500 BTU | Interior, permanent install | Small to mid-size vans, trailers, and builds with a compact interior mount spot |
| Propex HS2800 (this heater) | 9,500 BTU | Interior, permanent install | Larger vans, bigger trailers, and colder-climate builds |
| Propex HS2211 | 6,500 BTU | Exterior / underfloor, permanent install | Builds with no interior room to spare for a heater |
| Propex PS2000 Slimline | 6,500 BTU | Portable, no permanent install | Truck campers, tents, hunting and ice fishing shelters |
| Propex PS2000 Portable Heater System | 6,500 BTU | Portable suitcase, no permanent install | Rooftop tents, ice fishing, tailgating, hunting blinds |
How to choose: For a small to mid-size space with room for an interior mount, start with the HS2000. For a larger van, bigger trailer, or regular cold-weather camping, step up to the HS2800 for 9,500 BTU. No interior room to spare? The HS2211 mounts outside or under the floor and ducts heat in. Need heat without a permanent install? Look at the PS2000 Slimline or the PS2000 Portable Heater System. Camping high most of the time? Ask about the High Altitude Modification.

| Mount | Interior |
| Thermostat | Digital Digistat (included) |
