  • Different sized terracotta pots (two or more)
  • A portable folding stove
  • Canned heat


  • Start with setting up the folding stove.
  • Place the smaller pot on the top of the stove. Put it upside down.
  • Cover the hole on the base of the pot using a non-inflammable object. For example, a piece of foil paper. This will prevent the heat from escaping.
  • Next, place the bigger pot on top of the small one in the same way.
  • Remove the lid from the canned heat
  • Place fuel in the stove and light it.

Although the DIY terracotta pot would not be able to heat the entire room, it can undoubtedly warm up the immediate space instantly. This mode of heating is inexpensive and is one of the most innovative ways to create heat without power.

Create a Passive Solar Heating System

Create a Passive Solar Heating System

What could be more significant than using the sunlight to heat your home? Yes, using the sun’s heat is one of the most effective ways to heat home without electricity. Passive solar heating is the way to utilize the sun’s energy to create warmth inside a home.

The sun’s energy is combined with thermal mass in the passive solar heating system, reducing temperature fluctuations. The thermal mass used in this system could be a tile, water, rocks, concrete, bricks and other similar dense materials. Technically, six inches of mass would be good to perform the job.

For this, you’ll have to open the curtains and blinds on the south side of your home, where the sun shines extensively. Next, to absorb the heat from the sun, place the thermal mass in the path of sunshine. Be careful about putting an adequate amount of weight, keeping in mind what the structure can handle.

While absorbing the heat from the sun, you’ll have to be alert about closing the curtains and blinds when the sunshine fades. This is crucial to increase the insulation, which will lock the hot air in and keep the cold air out.

This alternative heating method will enable the warmed thermal mass to radiate heat indoors when it is dark.

Focus on Home Insulation

Focus on Home Insulation

The places that often witness wintry weather conditions should always check whether their home is adequately insulated or not. So, this is also one of the ways to keep your home warm even during a power cut.

It can be tough to maintain warmth indoors without power alternatives. Also, in the absence of proper insulation, the alternative heating options won’t work effectively.

To insulate your home suitably, follow the steps mentioned below;

  • To minimize heat loss, use foam board insulation on the exterior walls.
  • Spot air leaks around your house and fix them with caulking.
  • You can also apply weatherstripping on your doors and windows to prevent cold drafts.
  • Next, place a draft stopper between the window frames and the bottom of your door to seal the air passage.
  • Install insulated shades and place thick floor rugs to make your place cozy.

Opt for Wind Systems

The wind system will be the best pick if you want a heating system that can produce heat without electricity or gas. It happens to be one of the best alternate heat sources as it generates heat without polluting the environment.

You’ll have to buy a small wind electrical system for indoor use as the ones crafted for commercial use are bigger and more expensive. The indoor wind electrical system will use wind energy and convert the same into electricity.

Furthermore, this self-produced electricity can be later used to power heating systems and other electrical devices during power outages.

Use Rocks for Heating

How can we forget about heated rocks while discussing alternative heat sources for power outages? Yes, using heated rocks is one of the most efficient and handy ways to heat a room without electricity.

For this, you will need an open space outdoors where you can ignite a small fire using wooden sticks. So, to begin with, get some wood sticks and use the same to open a fire. Once you notice adequate flames, gather some big stones and place them near the burning fuel.

Next, observe the stones closely to see if they’re adequately heated. Once they look hot, bring them inside your room. This heated stone will radiate heat in your room, making it warm and cozy.

Caution: Do not touch heated stones with bare hands, as this might rip your skin out. Always use gloves or thick cloth to avoid casualties.

Burner Cans are Good Alternatives

A biofuel burner can is yet another handy alternative to produce heat without electricity. Burner cans are great to burn or light up different kinds of fuels like wood, or you can put them on and leave them in an open space to generate heat.

Biofuel burner cans are excellent for generating heat instantly. However, you need to be extra cautious while using the same. The most important part is to keep it out of your children’s or pets’ reach to avoid casualties.

Biofuel burner cans are suitable for emergencies, but you should not rely on them entirely, as using them often might get dangerous.

Furthermore, you should always opt for biofuel while choosing a fuel-based burner. For your information, biofuel is sourced from natural ingredients which do not produce harmful fumes.

As a result, they cause no damage to the environment. In addition, keeping sustainability in mind, always pick refillable and reusable cans so that you don’t add to the waste.

Warm Up Using Layered Clothing

Warm Up Using Layered Clothing

In the absence of a heating system or during power outages, you can remain warm using layers of warm clothes. For this, you should begin with essential thermal inner wear and then put on your sweaters to top it off with your jacket, depending on the weather.

Furthermore, you can also use fleece socks and woolen blankets to preserve your body heat for staying comfortable.

During such times, ensure all family members sit together under one or two blankets because that’s how you can share your body heat to feel more warm and cozy.
