How to keep one room warm when your furnace stops working

When the furnace quits in winter, you do not need to heat the whole house. This guide covers checking the thermostat and filter, sealing one room, and warming people safely with a space heater, blankets and hot water. It suits anyone facing a cold night or a two day wait for a repair.

Steps

  1. Check the thermostat screen and swap the batteries before you call anyone. A blank or dead display is often the whole problem.

  2. Replace the furnace filter. A choked filter can shut the furnace off, and this is the fix roughly one time in four.

  3. Pick one room and seal it. Tape plastic drop cloth over the windows with painter's tape and heat the people inside it, not the whole house.

  4. Find the drafts with the back of your hand, then close them with foam weatherstrip around door and window frames and foam outlet sealers on outside walls.

  5. Wrap exposed pipes with foam pipe insulation, let a tap drip, and find your water shutoff in daylight before you need it.

  6. Warm yourself, not the room. Put down a bath mat, heat a rice sock, fill jugs with hot tap water, and switch to flannel sheets.

  7. Run a ceramic space heater only when it is plugged straight into a wall outlet, 3 feet from anything that can burn, and off before you sleep.

  8. Put a battery carbon monoxide alarm inside the warm room and check the date on the back. The whole unit expires at about 10 years.

  9. Never heat the house with the oven, a grill, a camp stove, a generator or a propane heater. Cook supper in a small slow cooker in the warm room instead.

Tips and common mistakes

Keep one window that still opens clear, and never burn candles inside the sealed room.

Lay the heavy blanket on top of you, never underneath, and keep electric blankets flat and on low, never on a baby.

Hang a blanket over the doorway of the room you are heating and close off the rooms you are not using.

A space heater warms people in a small sealed room. It will not heat a whole house.

Questions

What should I check first when the furnace stops?

Thermostat batteries and the filter. A dead thermostat display or a clogged filter can stop the furnace before anything is actually broken.

Is it safe to heat a room with the oven or a propane heater?

No. Ovens, grills, camp stoves, generators and propane heaters give off carbon monoxide and can start fires. Use a ceramic space heater and a carbon monoxide alarm instead.

Why do I need a carbon monoxide alarm if I am not burning anything?

A blocked or cracked furnace flue can leak carbon monoxide even after the heat is off. The alarm is the only thing that warns you while you sleep.
