Cold! and mural finished

Arrived at the van at about 10pm on Friday, the much touted cold weekend!

I had been thinking for a while how to use the redundant heat of the car engine, making a makeshift storage heater, with stones/ a hot water bottle. Anyway, in the meantime I thought it would do to heat up my curry leftovers. Wrapped it up in foil and placedon top of the engine. It got warm after 20 minutes.
The temperature really dropped that night, I made a couple of videos to document.

When I arrived the inside temperature was about 7-8 C, this dropped steadily through the night. It did disturb my sleep, at about 3.30am to boil the kettle for my hot water bottle. The temperature reading then was 2.8 C inside. When I woke in the morning it was as below,

Saturday evening, I worked inside the van. A bit of body heat will help right?
I get the mural wallpaper finished and the right hand windowsill.

It's worked out pretty well. Saturday night was not so cold and I think my tactic of working to keep warm helped (it was after 11pm I downed tools). I kept the windows less open, and the CO2 reading was offscale in the morning (>6500 ppm), but the air felt OK, and airing in the morning brought it back to normal.

I have one tiny tear in the paper, and I notice in the morning that a hand sized section on the curve is not in contact with the wood, nothing I can do about either. I will add an angle moulding across the top next time, and varnish the paper for protection.

Now the winter projects need doing- upping the door insulation and adding a heat exchanging vent. In the meantime I will be more cautious planning to stay over!
