@skylar @PurpCat @WandererUber @deprecated_ii @lichelordgodfrey If you're trying to heat "the cold room" without upping the furnace temp, look at an oil filled radiator heater. Super simple tech, and the analog ones are the best. Look for one with two switches and a knob, like picrel. They're like $40 online or so and will often clearance around March.
>750 watt peak power with 1 switch on, 1500 with two.
>Heats oil inside so it doesn't suddenly get cold when it cycles off.
>Cozy and comfy radiant heat.
