On the subject of heat...

If I need it, I use wood. Usually though, the reptile heat bulbs/pads are enough.

We have an electric baseboard heater, our "house" is very very very very tiny so that's all we need. And besides our landlord pays all utilities

Electric.

Gas. We are buying an electric fireplace this weekend though, since gas prices are going through the roof

Wood. We have new woodstove for this winter and 10 cords of wood stacked up in the yard.

We also have a propane furnance for back up, but we rarely use it. We had electric baseboard heaters too, but we disconnected all of them. Way too expensive to even consider using them.

My furnace runs off of fuel oil &/or Kerosene. I can even mix the 2 together.
Fuel oil gums up below 30F so I usually just have Kerosene, it's a little more expensive but it's cheaper than replacing my furnace when the oil gums up & ruins it.
It's not that bad either, it costs me about $400-500 to heat all year long, even last year when we had a LOT of below zero days.
