A 1.9 litre Klean Kanteen of boiling water, will contain approximately 798KJ of heat energy. You can boil the water outside the vehicle with a propane stove or fire. Assuming the Klean Canteen is partially insulated i.e. a neoprene insulated cover etc, and the water bottle releases the heat over 30 minutes before getting cold, this will average approx a 400W space heater for 30 minutes. This will of course provide plenty of liquids for hydration also throughout the night. A lb Coleman Propane bottle/stove and high efficiency kettle would bring to boil around 30-40 litres of water. If adequate ventilation is provided then a Propane or Butane/propane mix Lantern might keep a vehicle warm throughout the night. Vehicles are notorious for being poorly insulated as with any metal box sitting in the snow.

Along with a sleeping bag such as a British Army 58 Pattern, I also will take along some British Army Bivi Trousers and Jacket as it can be quite chilly answering the call of nature in the middle of the night especially with the temperatures getting down to -15C to -20C recently.

BTW would anyone consider sleeping outside the vehicle using a self inflating mat and Goretex bivi bag. Getting some sleep is always a lot easier lying stretched out rather than in a reclined vehicle seat even after attempting to keep the vehicle interior warm.
