Does heat go out when power goes out

If a winter storm has hit your area and the power is off, you may be wondering: Does my heat go out? The answer depends on the type of heating system you have in your home.

Forced Air Heating (YES) - Most homes have forced air systems which require electricity to run. This means that your furnace will lose its heat if the power goes out.

Water Heater – Most water heaters will remain in operation even if the power is out, however, you should be aware that some high efficiency water heaters need electricity to operate.

Steam Heat – Though not as common these days, steam heating is also another type of heat that will not lose its heat if the power is out. This type of heat is a combination of hot water and steam which allows the water to rise and circulate throughout the home.

Gravity Heat – This heat source is not as common today but some older homes still use gravity heat. The furnace is in the basement and the heat rises up to the rest of the house.

Candles – Candles can provide light and warmth but can be dangerous if used incorrectly. They can cause fires and also release carbon monoxide which is deadly if you breathe it in.

Alternative Heat – Many survival websites recommend using fuel-based heat sources such as propane or kerosene heaters or generators to protect you from cold exposure if the power is out. Be sure to check out the warnings and tips for safely using these kinds of heat sources before they are ever used in your home.
