Do like jews do and put a candle in the back of your van.....if it's really cold then light it

Im thinking of using a leisure battery an inverter and one of those 55 watt tube heaters that are for green houses and conservatories.  The heater plugged into mains only costs 2p per day to run. Atm though I'm running an an extension cable to the van with a fan heater but I live in a terrace so its not ideal.
