Sorry to hear about your heating situation. Hope it gets resolved soon. We went down to 5 last night, tonight is to drop lower. brrrr.
I always keep a sack of potatoes for no heat situations. Boiling potatoes seems to warm up a room quickly.
There's also a portable sauna which can be folded away. Great to use just to warm up a bit and get a more positive attitude when waiting for a furnace to be fixed.
Well, ahh I kept a bit warmer being the one who was fixing the furnaces. People I knew and others were already doing service and delivery work.
Might have been a moment or two when the room turned blue heat with some language issues. No one around to hear this during the most difficult moments. I like the idea of boiling some potatoes. That moist warm air is as good as a humidifier.
Portable sauna eh, sounds more like a portable fish house with a sunflower heater.
