Is it likely cheaper to use a space heater than full central heating if you literally dont even use much of the space in the house that you never like go anyway? (lemmy.world)

Several years ago, I had a very lucrative, outdoor job over the winter. Between acclimating to the cold and long underwear, I would be roasting in "room temperatures". I lived alone, and was only home weekends and about 6 hours a night.

I turned my thermostat down to 50F, put an oil-filled radiator-style space heater on a timer in my bathroom, and a heated mattress cover on my bed.

Yes, you can save an ass load of money on heating bills.

If you have plumbing in exterior walls, you need to be careful. I had to leave the cabinets under my kitchen sink open to get some heat back to the pipes.

Is there a quick+dirty F -> C conversion? I know its something something * 0 + 32 or some shit but I'd love a super loose rule or affirmation of that if you know

[–] TauZero@mander.xyz 3 points 1 year ago (1 children)

The full formula is (F-32)*(5/9).

I have difficulty multiplying by 5/9 in my head, so the quick-and-dirty option is to subtract 32 and simply divide by 2.

50F - 32 = 18, divide by 2 = 9C (compare to actual value: 10C)

Very good :)
