Top Propane Heaters to Keep You Warm While Camping
When temperatures drop, a propane heater can be a van lifer’s best friend. Propane heaters are portable, affordable, and require no installation—just connect a tank and ignite. While they’re better suited for ventilated spaces or short sessions than overnight use, they excel at quickly warming a van before bed or taking the edge off a cold morning. Here are the top picks for camping and van life use.
1. Mr. Heater Big Buddy Portable Propane Heater
The Big Buddy is the most popular portable propane heater among campers and van lifers for good reason. It heats up to 400 sq ft, runs on 1lb canisters or a bulk tank with an adapter, and includes an auto low-oxygen shutoff for safety. It’s powerful, dependable, and widely available.
2. Mr. Heater Little Buddy
The Little Buddy is the compact sibling—perfect for smaller vans or solo travelers. It runs on a single 1lb propane canister and produces 3,800 BTU, enough to take the chill off any small space. It’s lightweight, simple, and very affordable.

- BTU Output: 3,800–18,000 BTU covers most van and tent needs; bigger spaces need more BTUs.
- Safety Shutoffs: Always choose a heater with tip-over and low-oxygen shutoff features.
- Ventilation: Even “indoor-safe” heaters require cracking a window—never sleep with one running in a sealed van.
- Fuel Compatibility: 1lb canisters are convenient; bulk tank adapters offer major cost savings.
- Catalytic vs. Open Flame: Catalytic heaters burn cleaner and produce less moisture than open-flame models.
- Portability: If you camp in a tent too, choose a unit that’s easy to carry outside the van.
Final Thoughts
Propane heaters are the quickest and most affordable way to add heat to your van or campsite. For safety, always ventilate your space and never run any heater unattended while sleeping. The Mr. Heater lineup remains the top choice for most van lifers, while the Olympian Wave series suits those who want a more permanent, low-profile solution.
Frequently Asked Questions
Are propane heaters safe to use inside a van?
Unvented catalytic and radiant heaters consume cabin oxygen and release water vapour and carbon monoxide, so they require a cracked window and a working carbon monoxide detector at all times. Vented propane furnaces that draw combustion air from outside and exhaust through the wall are far safer for sleeping through the night.
How much propane will I burn?
A small radiant heater on low uses roughly 0.1 pounds per hour, so a 20 pound tank runs about 200 hours at that setting, or eight to ten cold nights of intermittent use. On high, consumption triples. Cooking and a water heater on the same tank shorten that considerably.
What about condensation from an unvented heater?
Burning one pound of propane releases roughly a pound and a half of water vapour into the cabin. That is the main practical objection to unvented heaters in a van, since the moisture condenses on windows and inside walls. Anyone heating this way regularly should expect to run a fan and wipe surfaces daily.
Does it need any electrical power?
Portable radiant heaters need none, which is their main advantage during a dead-battery situation. Vented furnaces use a blower and control board, typically 2-6 amps at 12V, or 25-70W while running. That is 200-500Wh across a cold night, enough that you should size your battery bank accordingly.
How should the tank be mounted and stored?
Propane tanks belong in a sealed, exterior-vented locker or mounted outside the living space entirely, with the relief valve venting outdoors. Never store a tank loose inside a van. Secure it upright, use a flexible hose rated for propane rather than rubber tubing, and leak test connections with soapy water each season.
