Buyers’ guide to campervan heaters

Camping out of season can be fantastic – more space, fewer people and more months of fun and adventure. But how do you keep a campervan warm in winter?

Here’s our guide to the best caravan and campervan heaters…with best buys for portable electric heaters, portable gas heaters, blown-air parking heaters and more. 

 

Latest update: November 2020

Portable electric heaters for campervans and caravans

Possibly the cheapest and simplest option (after a hot water bottle and blankets), a portable electric campervan heater will give you instant heat in a compact package. You do, of course, need hook-up.

For instant heat, we’d opt for a ceramic fan heater. For super-safe warmth, choose an oil-filled or, better still, a lightweight oil-free radiator for your campervan.

Fan heaters

Simple, cheap and small, there’s nothing like a fan heater for instant warmth when you get back to the van after an autumn walk. 

A fan heater blows out warm air, so there’s some noise. Go for one with a decent thermostat, an auto shut-off and as quiet as possible.

We like the affordable Igenix (above) and the Warmlite. They can stand upright or lie flat to suit your space. Both under £15.

Kampa’s Diddy fan heater

Neat and small and a choice of 750W or 1500W blown heat. A good choice for a tent (with hook-up).

There’s no thermostat, though, so it’s either on or off! Around £22.

 

Ceramic heaters

A step up from a standard fan heater, these are safer, more efficient and still very affordable. They’re essentially fan heaters, but with a PTC heating element instead of a resistive wire. They don’t go red-hot if something gets in the way of the airflow, so they’re less dangerous in a campervan or caravan.

Again, lots to choose from. We rate the Pro Breeze (pictured top, around £40) and the £30 Comlife 600/1200W heater above.

ProBreeze also has a 500W mini heater that works well.

Plug socket heater

You can’t get much more compact than this plug socket ceramic fan heater. It’s 1000W and has an adjustable thermostat, a timer and safety cut-off.

You’ll need to check it’ll fit if your socket is close to the floor or another obstacle, as it needs some space below. Around £15.

Our choice for van and home

Oil-free radiators

Whereas oil-filled radiators use electricity to warm up the thermodynamic oil stored inside, oil-free have aluminium or ceramic inside. As well as safety, the advantage is that they’re silent. The disadvantage can be the size and weight.

There’s only only one oil-free small enough to go in a campervan or caravan. Fortunately, the Dimplex Baby (Eco Chico) is also great.

We use this mini oil-free radiator in our campervan (and in the porch at home when we’re not travelling). It’s small and light, heats up quickly and has a thermostat control. 

Output of 700W, weighs 5kg and 19 x 30 x 45cm. 30% more efficient than an oil-filled (apparently).

Around £50.

Amos oil-free radiator

We prefer the Dimplex for size, but this Amos radiator is a little cheaper. It uses mica technology and is silent. Plus you can choose 2000 or 1200W.

It’s 66cm (H) x 63cm (W) x 26cm (D) and weighs 4.65kg. Around £40. I’d still say too big for most campervans, but fine for a larger motorhome or caravan.

Oil-filled radiators

Very safe for campervans because there are no naked flames or heated wires. Oil-filled are slower to heat up than an oil-free, but retain heat better. There’s a teeny risk of oil leaking, but very rare.

Our choices would be these 500W models:

DeLonghi – 17 x 34 x 40cm and weighs 6kg

Igenix – 10 x 28 x 35cm and weighs 4kg.

12V van heaters


Don’t get excited! There are no 12V heaters that will keep you warm enough. You’ll see lots that look like this one (in black, grey or red, but all the same). They’re described as windscreen demisters and car heaters, but they really don’t do much at all. In fact, they’ve been known to simply fuse the system. Don’t bother!

On the other hand, heated seat pads do seem to work well. If your van has a 12V socket in the rear as well as the dashboard, then you could quite cosy sitting on one of these with a blanket or sleeping bag wrapped around you.

Halogen heaters

Sadly, we haven’t been able to find a halogen heater we can wholeheartedly recommend. Most are a bit too bulky for small campervans or are cheaply made and unreliable. 

The best we’ve found is the 400/800W Igenix at around £15.

Halogen heaters are the bright glowing ones – basically halogen lightbulbs that radiate infrared rather than light. They only warm up what’s directly in front of them rather than the air, but they look cosy. 

Carbon heaters

Carbon heaters use a lamp very similar to a halogen heater, but with a carbon filament.  The type of infrared is better at warming our skin, so a 500W carbon heater will give you as much warmth as a 1kW halogen. 

They’re efficient, but are really too tall for most campervans or caravans (in our opinion!). Best of the bunch is the 1000W Steba Veito at around £65.

There’s also a slightly cheaper and neater option from the Ironware brand, rated at 900W.

Portable camping gas heaters

If you wild camp or won’t have electricity, you’ll need either a built-in diesel or propane heater (see the next section), a solar-powered powerbank or a portable gas (propane or butane) heater.

Gas heaters may seem a simple option, but they’re not ideal. We really don’t recommend them for inside a campervan because of the very high risk of carbon monoxide poisoning and fire. 

If you really must have one, make sure you get an excellent CO monitor and always have plenty of ventilation. Never leave it unattended. As well as the danger of fumes, all gas heaters produce a lot of condensation.

Please avoid the Kampa Hottie, we’ve heard some near-horror stories about this one’s safety.

Heat yourself not your van?

Here’s another option that works well if you’re in and out of the van or tent a lot, or if you want something that has a use beyond camping.

There are lots of waist belts, bodywarmers and jackets that come with heat pads embedded. They’re powered by portable powerpacks (like the ones you use to recharge phones). You can see more about these in our camping power article.

It’s important to choose one that’s got good temperature control. We’re highly suspicious of the safety of some of these, so do read the bad reviews rather than the good for a clearer picture.

We’d opt for a belt rather than a jacket as it’s more versatile. The best we found was a graphene-based waist belt (now you ask…graphene is the one-atom thick material first isolated at the University of Manchester). Around £40.

Cartridge heaters

There’s nothing to choose between the Yellowstone, Topflame, Bright Spark and Highlander gas heaters. Like so many basic camping products, one factory seems to make the same item for lots of different retailers. We do try to point that out when we can, especially if you’re needlessly paying double for the same piece of camping gear!

They take butane cylinders and have piezo ignition (no matches needed).Heat output is around 1.3kW and the size around 28 x 19 x 28cm.

If you swivel the heater section to horizontal and add a little grill, you might even be able to make toast. Around £25.

Stove heater adaptor

If you have one of the tabletop cartridge-operated camping stoves like the Campingaz Bistro, you can also get a heater adaptor for around £12. They get VERY hot to touch. Some people use them on a campervan or caravan gas hob too.

Upright gas heaters

Another small option is the Kampa parabolic 700W cartridge-operated heater. This one doesn’t have an ignition. You’ll need something solid to stand it on. Around £20.

 

Old-fashioned heatstoneware hot water bottle

Great tip from reader Dave Harding. These vintage stoneware hot water bottles (provided you check for leaks) are a brilliant way to keep warm. And no plastic!

Blown-air parking heaters for campervans

New Year in the Trossachs but not at all chilly.

Many campervans come with heating as standard. That heating will be a blown-air system from the likes of Webasto, Eberspacher or Propex. The standard on the VW California, for example, is the Webasto Thermotop. You’ll hear these installed systems called ‘auxiliary’ or ‘parking’ heaters too.

 

Once installed, they’re cheap to run (diesel more so). You no longer need hook-up, so you’re free to wild camp in the snow. They give you the equivalent of central heating, often with a timer, remote control or app control.

Installation, installation

The key to efficient auxiliary heating is installation. All the top brands are reliable, so your choice of system should be guided by finding an installer you trust and who can put you in touch with previous customers.

 

Check with those fellow campervanners how the installation went and whether they’re happy with the result.

Installation usually involves cutting through the bottom of your floor. Yikes! That’s why you don’t want a cowboy riding into town. There’ll be an air intake, an air exhaust, a fuel line running from your tank to the heater, power wiring and thermostat control wiring.

Diesel and propane heaters warm slowly and steadily rather than the blast of a fan heater, so tend to be more comfortable. They create little condensation too. Expect to pay between £1,000 and £2,000 for the equipment and installation.

Do-it-yourself?

Of course, if you’re a skilled mechanic and you’re building your own van from scratch, you can just buy the kits for diy installation (Triclicks is a good ‘un). 

Ebay is also a great source of affordable new diesel heaters and the reviews of the dealer can usually be trusted.

 

The Triclicks diesel heater kit is pretty well thought-of and a very good price if you feel confident enough to DIY your heater (or if you know a friendly fitter).

Around £110 and comes with everything you need, including a remote control.

Questions to consider and ask your installer:

  • Can you put me in touch with previous customers?

Can you show me what the internal fittings will look like? We’ve seen some outlet pipes that stick out rather obviously, for example, and plastic grilles that don’t match the inside colour scheme.

You wouldn’t know this intake grille was retrofitted.

We weren’t keen on this type of outlet. Flush is better.

  • Can I check how much noise it makes (both inside and outside? Could you (and your neighbours) live with that level on a quiet campsite in the dead of night?
  • What are my options for controlling the system?
  • What about SIM-enabled systems that I can control from an app? These are expensive. Do you want the extra expense of a SIM contract? What happens when you’re in a no-signal area? What happens to data roaming if we leave Europe? We chose NOT to have this control based on all those uncertainties.
  • Should I pay extra for a remote control? Again, this adds cost. They only work within a short range. Given that it’ll take five to 10 minutes for the van to warm up, it’s only really useful if you’ll use it from the comfort of your house before you get into the van in the morning. If you’re imagining turning it on as you walk back to the campervan after a hike…well, you’ll be back at the van before there’s much warmth.

Diesel heaters for campervans

Diesel parking heaters draw fuel from the main diesel tank and through a burner/heat exchanger under the vehicle. They then duct hot air into the van through a small grille. The combustion happens safely underneath the van.

 

You don’t need to run the engine. They work independently. Diesel heaters can be a bit noisy, but some come with mufflers and insulated boxes to lessen the sound.

You’ll get around four hours of continuous run-time for around a litre of diesel (based on Webasto Airtop 2000)

The main brands are:

Propane campervan heaters

Propane-fuelled systems are similar to diesel systems but, of course need a fuel supply. This could be a disposable canisters or refillable propane tank.

 

If you’re already using propane tanks in your van, you may be able to tap into your existing propane lines.

Propex is the brand of choice (the other is Truma, but these seem to be preferred by motorhome and caravan owners). The Propex systems come in a range of sizes for small campervans to big motorhomes. Some models are installed underneath the vehicle, others go in  a bed-box or cupboard.

 A 13kg propane tank will give you around 90 hours of heat from the smallest Propex furnace.

Propex also do a dual-fuel gas/electric heater for when you’re on hook-up.

Propane systems will often struggle or not work at all above a certain elevation. Ask your installer if you expect to be camping in the mountains.

Woodburning stoves

While we love a woodburning stove outside on an autumn night (have a look at our guide to woodburners for camping), stoves inside the van are really only for live-on-board campervanners. 

The disadvantages are many – the risk of fire and carbon monoxide poisoning, the work involved in installing it and the danger of having super-hot surfaces in a small space.

Keep your woodburner for outside the van

Despite our reservations…there are those who love their woodburner, and there are stoves small enough to fit in a van. Consider, though, how much space you’ll also need for the heat protection around it, for the chimney and for the fuel.

The photo of that cute stove and kettle might make some of you go: “Yes! That looks gorgeous”. I just get the collywobbles.

Instead, get yourself a portable woodburner for warming up outside with a view of the stars!

We like the DWD and Outbacker stoves. You can cook on it and boil water for your hot water bottle in the great water heater attachment.

If you’re a safe and happy campervan woodburner, set us straight, of course.

Keep warm in a campervan the low-tech way

It’s very possible to stay warm in a campervan or caravan without any heating at all. It’s all about and  piling on the layers of clothes, blankets and sleeping bags.

  • Insulated thermal (silver) screens for your windows will keep in a lot of heat. Buy them off the shelf or get them custom-made. Maypole are great for VWs.
  • If you’ll be using the pop-top roof, think about insulation there too. You can make your own inside using insulation fabric (be careful you don’t create condensation between the fabric and the roof canvas). Or get a pop-top roof cover that goes over the outside to keep in heat and keep out rain (or snow!). We like the German-made Calitop because it comes in separate parts, which makes it easier to fit.
  • Don’t forget the hot water bottles.

  1. We always used a simple thermostatic convector heater – £30 from Argos – job done even in subzero temperatures in 25 yr old van. ED: Good tip, Peter. These convector heaters are good, but too big for a smaller campervan, I think. We tried a model with three settings (750, 1250 and 2000W) and it was definitely warm, but took up a lot of space. Watch your hook-up power requirements too. Have a look at our article on power for camping – there’s a useful chart that sets out campsite electricity ratings and what individual devices need.

  2. If you’ve got access to a microwave try SnuggleSafe Microwave Wireless Heatpad, we’ve got one for our dog but there’s no reason not to use it instead of, and better than, a hot water bottle. It really does last about ten hours in normal use.

  3. Hi. I worry that a hot water bottle might leak. We have a microwave in our caravan which we will use to heat up our wheat bags. They dont stay hot for long but quite good at warming your bed before you get in. Otherwise we are going to try an electric blanket.

  4. philip mckeown

    get a 5 season carp sleeping bag. ED: Great tip, Philip. They’re heavy, but you won’t find warmer at such good prices. The NGT five-season is only around £45, for example. Not for backpackers, though.

  5. Stoneware hot water bottleFor overnight use fill an old stone-type hot water bottle. They stay hot for over 12 hours we found! Picked up at a local auction. Best £1 we’ve spent so far. That and a good quilt is wonderful and cosy! ED: Brilliant tip, Dave. There are masses of them for sale very cheaply on Ebay. I’m guessing you just need to double-check that there are no leaks. They look very repairable, though, and great not to be using plastic.

  6. It is worth knowing that at low temperatures – effectively below 5 degrees Celsius – Butane stays liquid in its bottle and you can’t ignite a burner. In Scotland this can be September through to May.
    So if you looking to heat your van ☹️ or do a fry-up outside ? you need propane, or in extremes one of the more specialised propane mixes. ED: Thanks so much for the tip. Take note everyone.

  7. You can now buy electric ‘hot water’ bottles which charge up to be switched on when you need them. I haven’t tested one but am thinking about getting hold of one to try. I don’t think they have any water in them. More like a battery powered heat pack so could be quite useful for some instant heat at night. Personally I’d go for a branded one though because I’m not sure how much I’d trust a cheap version. ED: Nice idea, Dave. We did look at these a while back and sadly didn’t find any that worked that well. They have to be mains charged and, to be honest, many looked more faffy than simply boiling a kettle of water for a traditional hot water bottle. We always save any excess boiled water from making tea and so on in a couple of flasks. It stays warm enough to fill a hot water bottle at night, or can be given a quick reheat if not. We like the eco-sustainable rubberless bottles made in Germany. No smell!

  8. electric blanketI use a 40w Silentnight electric blanket run off a 150Wh power station to keep warm at night car camping. It doesn’t need to be on full power all night. ED: Thanks, Simon. Also thanks for answering our questions about the actual kit you use. The electric blanket is a Silentnight Comfort Control. The Suaoki Power Station isn’t available any more, but have a look at our guide to camping power to see some good alternatives.
