The Best Gear For Keeping Warm In Your Caravan

Cold country is where a big lap gets uncomfortable fast. This is the curated shortlist of gear that actually keeps you warm in a caravan, from the diesel heater that runs your winter to the $50 blanket that quietly does more than any of it. Every pick here is pulled from our deeper heating guides, so you can grab the best of each category in one place.

There is no single product that keeps a van warm. Staying comfortable through a Tasmanian winter or a frosty Red Centre night is a layered job: a proper heater for the air, a 12V blanket for the bed, something to sit in outside, and a couple of cheap fixes to stop the whole van fogging up with condensation. Here is the best of each, curated from across our heating guides so you do not have to read six of them to kit out.

Diesel Heaters: The Off-Grid Workhorse

If your lap includes real cold, a diesel heater is the single best upgrade you can make. It burns a tiny amount of diesel in a sealed chamber, vents the exhaust and all the moisture outside, and blows bone-dry warm air into the van. Once running it sips under 1.5 amps, so it works for nights on end off solar and battery. Two picks cover almost everyone.

Best value: Autoterm Air 2D (~$1,299). This 2kW unit is the one experienced big lappers keep recommending, and for good reason. It sits just below the European premium brands on price but matches them on reliability and genuine Australian support, sipping 0.10 to 0.24 litres an hour. Add the Comfort controller for proper thermostatic control and it is hard to fault for the average single-axle van. Check price at Caravan RV Camping →

Best premium: Webasto Air Top 2000 STC (~$1,700+). Webasto is the name the whole industry measures itself against. This 2kW unit runs reliably in deep sub-zero cold, but the real reason to pay up is the nationwide service and parts network. When you are three days from a capital city and something needs looking at, that coverage is worth the premium on its own. Buy it if you are full-timing through serious cold and want to stop thinking about your heater. Check price at Caravan RV Camping →

Fixed Gas Heater: The Quiet Powered-Site Pick

Truma VarioHeat Eco / Comfort (~$1,819+). If you spend most nights on powered sites and value silence, a fixed flued gas heater is the quiet alternative to diesel. The VarioHeat is the current standard in new Australian vans: whisper quiet, fast to warm up, flued so it vents safely outside, and drawing only 0.65 to 2.75 amps with no glow-plug startup spike. The Eco runs to 2.8kW and the Comfort steps up to 3.7kW for bigger vans. The catches are that fixed LPG must be installed by a licensed gas fitter with certification, you are tied to bottle swaps, and it adds slightly more cabin moisture than diesel.

Electric Heater: Cheap Warmth On Mains

KickAss Electric Panel Heater 1000W (~$99.95). When you are plugged in, nothing beats an electric heater for cheap, zero-combustion, zero-CO warmth. This one is designed for camping rather than the lounge room: a slim 1,000W panel you can wall-mount or stand up, with a proper thermostat (1 to 35°C), a 24-hour timer, overheat and anti-tip cut-outs, and a whisper-quiet run. Best of all, it stows flat instead of eating a cupboard the way an oil column does. Just be clear-eyed that at 1,000W it is powered-site territory, and it will not heat a big van fast in alpine cold. There is also a 500W version for tighter spaces and lower draw. Check price at KickAss →

12V Electric Blanket: The Standout Buy

KickAss 12V/24V Electric Blanket (~$49.95). If you buy one thing off this whole list, make it this. A 12V blanket heats the person, not the air, which is the smartest comfort-per-watt trick in the book. It draws about 50W (4.2 amps) straight off the house battery, so you can free-camp in the cold with the heater off overnight and still climb into a warm bed. You get three heat levels, a 45/90/120-minute timer, an auto shut-off at 65°C, and a detachable, machine-washable controller. At fifty bucks it transforms cold nights, and every off-grid big lapper should own one regardless of what heater they run. Check price at Snowys →

Heated Camping Chair: Comfort At The Campfire

KickAss Ultimate Adventure Electric Camping Chair (~$149.95). Half the joy of the lap is sitting outside of an evening, and in cold country that gets old quickly. This chair heats both the seat and the back across three settings, is rated to 200kg, and scores a genuine 4.5 out of 5 across its reviews. It is the pick for retirees and couples who like to linger by the fire once the sun drops. The heating runs off a USB power bank (not included and not hardwired), and yes, $150 is a lot for a camp chair, but on a frosty night it earns its keep. Check price at KickAss →

Condensation & Comfort Extras

Warmth is only half the winter battle. A heated van full of breathing bodies and boiling kettles turns into a condensation factory, and wet windows lead to mould. These cheap extras finish the job.

A carbon monoxide alarm. Non-negotiable if you run any gas or diesel heater, and doubly so with a budget diesel unit. A cheap CO alarm is a few tens of dollars and it is the difference between a safe night’s sleep and a genuine emergency. Fit one, test it, and mount it at head height near the bed.

Moisture absorbers or a small dehumidifier. Diesel heat is dry, but gas heat, cooking and simply breathing all add water to the air. Damp-absorbing tubs (the DampRid style, a few dollars a refill) sit in a cupboard and quietly pull moisture out. If you spend long stretches on power, a small 240V dehumidifier does the same job far faster and dries a damp van out overnight.

Draught seals. Warm air leaks out of the gaps you never notice, around the door, the vents and older window seals. A roll of self-adhesive foam or rubber draught seal is a couple of dollars a metre and pays for itself the first cold night by keeping the heat you paid to make inside the van.

Thermal curtains and window covers. Single-pane caravan windows haemorrhage heat after dark. Insulated thermal curtains or magnetic-fit window covers trap that warmth in and cut the condensation that forms on cold glass. They pull double duty in summer too, blocking heat out, which is why we cover the best of them in the insulation guide below.
