Room heat calculator
Type your room size. See how much heat it needs and which miners can warm it while they mine.
Your room needs about 1,500 W
That's about 5,118 BTU/h of heat to keep it warm on a cold day.
Rule of thumb: about 10 W per sq ft for an average room with an 8 ft ceiling (7 W if it holds heat well, 13 W if it's drafty). An estimate, not a heating survey.

None of the miners we track give off enough heat for a room this big. Try a smaller room, or use a miner as a top-up next to your normal heat.

Questions
How much heat does a room need?
A common rule of thumb for electric heat is about 10 watts per square foot for an average room with an 8-foot ceiling. Use less for a well-sealed room and more for a drafty one. It's a starting point, not an exact number.
Does a miner heat as well as a space heater?
Yes, watt for watt. Nearly all the electricity a miner uses comes out as heat, like an electric space heater.
What if the miner gives more heat than my room needs?
Most heater miners have lower power modes or a thermostat, so they can run cooler. At full power a big one will overheat a small room.
What does 1,500 W mean for my outlet?
A US 15 A, 120 V circuit should carry about 1,440 W continuously. Put big units on their own circuit and follow the maker's guidance.
