Aside from having your ‘building’ be a vehicle or immolating yourself, is there a way to heat the interior of a building? It appears that wood-stoves don’t actually create any heat.
They should, any sort of fire should heat up the air in a range IIRC.
Yet another reason why vehicles are superior to houses, I’m surprised the debs haven’t added mobile homes that have wheels but no engine or controls.
also, on the heat topic, it still seems that our PCs can be very cold at 31C :P. I already dread the winter 
the ice labs are even worse. im walking around in 3 layers of heavy winter gear and im still chilly. and ultra encumbered.
being near any fire source should heat you up, including indoor wood stoves.
