In our modern society, we often take the warmth of our homes for granted. Most of us do not even understand how the intricate heating system of our homes uses electricity or natural gas to keep us warm when it's chilly outside.
However, when the power goes out, and we must resort to alternate heat sources, we are quickly reminded of just how privileged we once were—and how rapidly the cold settles into our homes and bodies without a functioning heater.
For those of you whose homes rely on an electric heat system to stay warm, don’t stop reading now. Below we will talk about how to heat a house without electricity so that you can keep yourself and your family warm when the power grid fails.

According to the U.S. Energy Information Administration, roughly 36% of households in the United States rely on electricity to heat their home. Throughout all the regions of the country, there are roughly 12.1 million households that rely on electric heat pumps. Moreover, the majority of these homes, roughly 9.3 million, are located within the hot and humid regions of the Southeast, where electrically powered heating is most effective.
Electric heating pumps are less common in colder regions of the United States. However, over the years, advances in electrical heating technology have made electric space heating more accessible to households living in regions with lower winter temperatures. For example, in 2015, 1.3 million households in the cold (and very cold) climate regions of the United States used electric heating systems. And even if you use a natural gas furnace, without electricity to run the blower motors, these heaters don’t work either.
So then, how do the folks living in the Southeast stay warm if a hurricane shuts down the power? And how do the families in the northern parts of the United States stay warm when a blizzard knocks out the power grid? Or what about the households that are located in the best places to live off-grid and choose to live without municipal electricity on purpose?
For these families, having alternative heat sources for power outages is a vital component of their self-reliant livelihood. Alternate heat sources mean they can keep their families comfortable and warm during even the darkest and coldest times.
You don’t have to be cold because the power goes out. There are various ways you can stay warm even without electricity. Below we will share five alternate heat sources that can help keep out the cold.
Propane heaters are an ideal plan B for heating when the power goes out. Propane is a great fuel source because it can be used indoors and has an extremely long shelf life. Propane will also emit a telling strong odor from a chemical additive called mercaptan that will alert you when there is a leak.
Portable propane heaters are lightweight and efficient. As you begin shopping around, make sure to purchase only propane heaters designed for indoor usage.
High-quality indoor propane heaters are very safe. Many of the best models will come with an oxygen depletion sensor, which will shut the heater off if there is inadequate oxygen for complete combustion. Many of them also have tip-over sensors that will shut off the heater in the event the heater is accidentally knocked over by a clumsy pet or family member.
Store-bought heaters are fantastic. But we also think it’s an important skill to know how to completely improvise and create a DIY heater with objects you already have around the home or cached in your emergency supplies.
Terracotta pots are versatile. They look good in displaying your plants, and you can repurpose them to make a DIY heater. It’s important to mention that terracotta pot heaters will not heat an entire house, but can provide warm localized heat.
Materials you will need:
Just put candles inside one pot and light them. Place the other terracotta pot on top upside down to create a covered dome. The candles will heat the pots and radiate heat around the room.
If you don’t have any terracotta pots lying around, that’s okay. You can construct a DIY stoneware heater instead.
You construct stoneware heaters in the same way as terracotta pot heaters. However, instead of using a terracotta pot, you can use the ceramic stoneware dinnerware you have in the kitchen.
Soda can burners are lightweight and portable DIY heaters. They make good additions to your survival kit so that when you’re stuck outside in the cold, you can provide at least a little warmth, cook food or boil water.

The idea behind a soda can burner is straightforward. Essentially, a soda can is used as a reservoir to hold alcohol. The can is filled and then ignited. When the fuel is ignited, flames pour out of the holes in the can to function as a miniature stove.

A step-by-step manual of how to make DIY terracotta, stoneware, and soda can heaters or stoves goes beyond the scope of this article. However, we found a variety of helpful YouTube videos made by homesteaders and preppers after a simple search for each type of DIY heater.
Using wood as fuel has been a strategy for staying warm for centuries. Wood-burning fireplaces and ovens continue to be an efficient way to heat your home without electricity.
However, there are a few drawbacks to wood fireplaces and stoves.
The first is the extra labor required to make them work. Obviously, you need to prepare the fuel ahead of time, which can be labor intensive. Fireplaces and stoves also make quite a mess and leave behind an odor (although many of us like the smell). Fireplaces, chimneys, and ovens also require routine cleaning to prevent buildup.
But if you can look past the extra work involved with heating your home with a wood-burning fireplace or oven, wood-burning stoves and fireplaces are extremely reliable and efficient.
When the power goes out, alcohol heaters are another viable option for creating heat without electricity. Denatured alcohol, like propane, is an ideal fuel source for preppers because of its indefinite shelf-life. Denatured alcohol is also safe to burn indoors.
Nowadays, there are many different types of alcohol heaters on the market. The best models are lightweight and highly portable. In addition, modern alcohol heaters are efficient. Typically, a quart of alcohol fuel will burn for upwards of five hours on its highest setting, and longer if burned on its lower setting. They are also versatile—working as a heater and stove.
Let’s not forget the most extraordinary heater at our disposal—the sun. There are two ways to harness the sun's energy to heat your home.
Passive solar heating relies on the heat your home can gain while the sun shines on it throughout the day. The heat that passes through your windows and skylights is absorbed into the home, typically the flooring and walls.
For best results, your home needs modern insulation and energy-efficient windows and doors. You can also make minor renovations to your home, like adding south-facing windows and skylights to allow more sunlight to heat the house.
2. Active Solar Heating
Active solar heating systems are much less common. The reason is that they require professional installation and a higher initial cost. However, if you have the budget to invest in an active solar heating system for your home, it will pay dividends in the long run.
In an active solar heating system, the sun’s energy warms up water or air stored in the roof panels. Then, the heat from the solar system is transferred into the living areas of the home with a blower or radiant heat system.
An obvious drawback of this system is that it requires electricity. However, some solar systems power themselves with the sun’s energy and not with electricity from the power grid. You can also consider using an emergency generator to keep your active solar heating system functioning.
The heating systems that provide warmth to our homes function safely by themselves most of the time. Besides carbon monoxide detectors, we typically don’t take many other safety precautions.
However, if the power goes out, you will need to improvise; and depending on the alternate heat source you improvise with, you may need to take extra steps to keep your home and family safe. Make sure not to use other heat sources indoors if they discharge carbon monoxide. Families die every year from moving a charcoal BBQ grill indoors for heat.
Here are seven
fire safety considerations we recommend considering when using alternative heat sources without electricity:
Most of us rely heavily on the heaters in our homes to keep us warm. We crank up the thermostat to stay warm when it gets cold outside, and often forget that there are other actions we can take to stay warm, regardless of whether the power is out or not.
If you have ever lost power due to a natural disaster like an earthquake or hurricane, you know how quickly it can get dark and cold. You also know how uncomfortable you and your family can be without an alternate heat source.
Don’t take chances. We recommend preparing for the unexpected so that you know how to make heat without electricity when the power grid fails.
