To be honest if the caravan does not have heating already there, a fan heater or small oil filled radiator would do the job and be more cost effective.I.M.O.

I have a gas blown heating system but mostly use a fan heater. Free on sites where you pay a set price for electric. I feel happier to put it on a low setting over night. I have gas and co2 alarms but still happier with electric over night. Caravans are not hard to heat.
