Was in the same boat earlier this season when So Cal was cold. Live in an industrial loft within my business. No central heat. Been building an Igloo in the loft made out of thick Polyurethane insulation sheets. Now have two space heaters. Just bought a small Halogen shop light for the office ($16 at Lowes). Gives off good light and also excess heat. So Cal has been warm the past few weeks due to the High Pressure Blocking factors that are now freezing Florida.
Resourcefulness! I’m huddling next to my desk lamp right now. It’s also amazing how much heat a monitor gives off.
That juxtaposition sounds scary from a potential fire point of view.
I would used only non-exposed element sort of heaters in that situations, like oil-filled convective heaters.
Glad I spent money ten years ago insulating and re-glazing my old mobile home up in here in Washington State. A small ventless propane heater (~20,000 BTU) will keep it at 65 even when it is 0F outside. Furnace doesn't even have to come on except to warm it up to 70 in the morning.
