I am in the UK so expecting a lowest temperature of around -5 celsius. I think I wasn't clear enough I am only using this method to heat the van up before I go to sleep, and switching it on in the morning to warm the van before I get out of bed, so the engine will be idling for 30min max on cold days (the remote start system cuts the engine after 15 minutes of inactivity).
I don't have any electrics installed yet, I need to get a battery to battery charger before I can charge my leisure battery.
But it's reassuring to know that a good sleeping bag etc can get me through the night if worst comes to worst.
Thanks for the thorough response.
