Heating Your Campervan: Diesel Heaters vs Wood Burners
If you want to use your campervan for more than a few weeks of summer, heating isn’t optional — it’s the difference between a van you enjoy all year and one that sits on the drive from October to April. And in the UK, that’s most of the year.
Two options dominate the conversation: the practical, ever-popular diesel heater, and the romantic, characterful wood burner. They heat a van in completely different ways and suit completely different owners. Here’s an honest comparison to help you choose.
Diesel heaters — the practical workhorse
A diesel air heater is the default choice in modern conversions, and for good reason. It draws a small amount of fuel (usually from a dedicated tank, sometimes the vehicle’s own), burns it in a sealed combustion chamber, and blows warm air into the living space through ducting. All the combustion gases are vented safely outside the van.
The upsides:
- Set-and-forget warmth. Push a button, set a temperature, and it holds the van cosy — even overnight, even while you’re out. Many run on a timer or thermostat so you wake to a warm van.
- Dry heat. Because combustion is sealed and vented outside, it doesn’t add moisture to your living space — a big plus in the condensation battle.
- Compact and space-efficient. The unit tucks away under a seat or in a locker; you lose almost no living space.
- Efficient. It sips fuel, so a tank lasts a long time, and there’s nothing to carry or store.
- Safe and controllable when properly installed, with the exhaust routed outside.
The trade-offs:
- There’s a low hum from the fan and fuel pump — most people tune it out, but it’s there.
- It relies on electrics to run, so you need enough battery/power (usually a non-issue with a decent system).
- It lacks the romance of a real flame — it’s an appliance, not an experience.
For the vast majority of van owners who want reliable, effortless, dry warmth all year, a diesel heater is the sensible answer.
Wood burners — the romantic option
A tiny wood burning stove brings something a diesel heater never can: a real flame, a gentle crackle, and that unmistakable cosy-cabin feeling. For some people, that atmosphere is the whole point of van life.
The upsides:
- Unbeatable atmosphere — nothing matches a real fire on a cold, dark evening.
- Fierce, satisfying heat — a wood burner can pump out serious warmth.
- Off-grid independence from fuel systems — burn wood you gather or buy; no diesel, no reliance on your electrical system to produce heat.
- Character — a stove becomes the heart of the van.
The trade-offs — and they’re significant:
- Space and weight. A stove, its flue and the required heat shielding take up meaningful room in a small van, plus you need somewhere to store wood.
- Effort. You have to light it, tend it, and it won’t run unattended or overnight — no waking to a pre-warmed van, and you can’t leave it burning while you drive or sleep deeply.
- Heat control. It’s less precise; small vans can go from cold to sauna quickly.
- Safety and installation. Fire, a hot flue and combustion inside a small space demand very careful, correct installation, proper heat shielding, and a carbon monoxide alarm as an absolute must. This is not a corner to cut.
- Mess and maintenance. Ash, wood, cleaning the flue — it’s a hands-on relationship.
A wood burner suits someone who loves the ritual and atmosphere, has a big enough van to house it safely, and doesn’t need push-button, overnight warmth.
Head to head
| Diesel heater | Wood burner | |
|---|---|---|
| Convenience | Push-button, thermostatic, runs overnight | Manual, needs tending, not left unattended |
| Heat type | Dry, even, controllable | Fierce, atmospheric, less precise |
| Space | Compact, hidden | Bulky, plus wood storage |
| Moisture | Adds none (sealed & vented) | Generally dry, but adds handling/mess |
| Atmosphere | Functional | Wonderful real flame |
| Best for | All-year, all-weather, fuss-free warmth | Cosy character, larger vans, hands-on owners |
Can you have both?
Some owners do exactly this: a diesel heater as the reliable, everyday, overnight workhorse, and a small wood burner for the atmosphere on special evenings. If you’ve got the space and the budget, it’s the best of both worlds — practical warmth when you need it, romance when you want it.
Our take
For most people, most of the time, a quality diesel heater is the right primary heat source: dry, efficient, effortless and safe, keeping the van comfortable through real UK weather without you thinking about it. We fit proven, industry-leading heating (Autoterm is a favourite) precisely because reliability matters when it’s cold and you’re miles from anywhere.
If a wood burner is your dream, it can absolutely be done — but it has to be installed properly, with correct shielding, flueing and safety measures. This is firmly in “get it done right” territory: gas, fire and carbon monoxide are exactly the risks a professional build exists to manage.
Whichever you choose, pair it with good insulation and sensible ventilation — heating, insulation and airflow are a team, and the warmest, driest vans get all three right.
Choosing yours
Diesel heater or wood burner comes down to what you value: effortless, dry, all-year warmth, or the irreplaceable atmosphere of a real flame. Most owners are best served by a diesel heater; a committed few will never regret their little stove; and those with the space can have both. Just make sure whatever you choose is installed safely — with heating, that matters more than anything.
