Diesel Heaters for Vans

Diesel heaters for vans keep a camper or work van warm all night for a few pence an hour, running off the leisure battery with the exhaust outside. Most insulated panel vans need a 2kW heater; a large or bare-metal van is better with 4kW to 5kW.

Pick a kit if you want a permanent under-seat or under-floor fit, or a portable all-in-one to try one out. Every heater here is 12V and rated 4 stars or more. Fit a carbon monoxide alarm whichever you choose.
