Can you use the Propex PS2000 in a tent?

Yes, and that is the point of the ducted design. The heater and its sealed combustion chamber sit outside the tent; only the warm-air duct and the thermostat wire come in. The exhaust never enters your living space, which is what separates it from an unvented propane heater.

Does it add condensation inside the tent?

No. Unvented propane heaters release water vapour along with heat, which is why tents run with them get damp. Because the PS2000 vents combustion outside, the air it pushes in is dry.

What do you need to run it besides the heater?

A 12V power source and propane. We run ours from a portable power station and a standard 20 lb tank. The draw is small, about 1.4A at 12V, so a mid-size power station carries it through the night.

What is the one setup mistake to avoid?

Connect the thermostat to the heater before you connect power, and disconnect power before you unplug the thermostat. Powering the unit with no thermostat attached will blow a fuse. Our setup guide walks the full sequence.

Is it worth the price over cheaper alternatives?

A Mr. Heater Buddy costs a fraction and is the right call for taking the chill off for an hour with the door cracked. The PS2000 is for sleeping through a freezing night with the tent closed, thermostat holding a temperature, and no exhaust or moisture indoors. You are paying for unattended overnight heat, not more BTUs.

AI-RESEARCHED INSIGHTS

Quick Verdict

Great For

Cold-weather tent camping, plus vans and small trailers. The combustion chamber is sealed and the unit sits outside the tent, so only clean, dry heat comes down the duct.

Not Ideal For

Backpacking or any trip where weight matters. It is a 38 lb system that also needs a 12V battery and a propane tank.

Sealed combustion chamber: exhaust vents outside and never enters the tent, so it heats without putting carbon monoxide or moisture into your living space.

It is a system, not an appliance. Budget for a 12V power station and a propane tank on top of the heater itself.

About This Gear

The Propex PS2000 Portable Heater System brings clean, dry air to your tent. Its compact design and simple installation offer hassle-free use, ideal for campers. The heater runs quietly on propane, making it safe and easy to use. Installation requires a bit of know-how, but nothing the average camper can't master. It does require a portable battery and a source of propane.

Our Take

From our own trips, not from reviews

The first time we ran these with the Outdoorithm Collective was a cold, damp Presidents Day weekend at Alice Eastwood Group Camp on Mount Tamalpais, where you can hike straight into Muir Woods from the sites. Most of those families had never camped before. The heaters put warm, dry air into every tent all night, which is the difference between a first trip a family repeats and one they endure. One family had flown out from Washington, D.C., and turned a heater down on the first night: it read as a luxury nobody needed. By the next morning the kids were lobbying hard. The parents relented, took a heater for the remaining two nights, and said it was the thing that kept the tent at a temperature anyone could actually sleep at. On their next trip with us, they asked for a heater before anything else.

Most reviewers
Ducted design. The heater sits outside and only the warm-air duct comes in, which is what makes it usable with a tent rather than only a van.
Most reviewers
Thermostat-controlled, so it holds a set temperature through the night instead of running flat out.
Most reviewers
6,500 BTU on a 1.4A 12V draw, so a mid-size portable power station will carry it overnight.

Most reviewers
The thermostat must be connected before power, every time. Reverse that order and you will blow a fuse.
Most reviewers
38 lbs in its case, and the price sits well above any other tent heater.
Most reviewers
The exhaust outlet runs hot and needs about a foot of clearance from tent fabric and guy lines.

Excels In

Freezing nights in a family tent, where an unvented heater would add condensation and risk.
Vans and small trailers, the market the unit was built for.
Cold desert nights, where the drop after sunset is the whole problem.

Limitations

Needs a 12V power source and a propane tank, so it is a car-camping system.
38 lbs in its case.
The duct has to enter through a door or window, so the tent has to allow for it.

What People Are Saying

Aggregated insights from expert reviews and user feedback

Community Consensus

Independent review coverage is thin because this is a niche system rather than a big-box heater. What coverage exists, and our own use, lands in the same place: sealed combustion plus a thermostat gives you a warm tent overnight without the condensation or the carbon monoxide risk of an unvented propane heater.

What Users Love

sealed combustion keeps exhaust out of the tent
dry heat, no added condensation
thermostat holds a temperature overnight
runs all night off a portable power station

Common Concerns

price
weight and bulk
needs both propane and a 12V battery to run

Durability Notes

Propex has a long track record in RV and van heating. The PS2000 packs that same unit into a hard case so it can travel.

Sizing Info

Rated 6,500 BTU, which suits a large family tent or a van. Keep duct runs as short as you can for best output.
