Non Electric Heaters: How To Keep Warm During A Power Outage

By Just In Case Jack | Last Updated: May 5, 2022

Old Man Heating His HandsToday we’re giving you a comprehensive guide on the best indoor heaters that don’t require electricity.

OR how to keep you and your family warm when there’s a major power outage.

Because having an emergency heat is key to living a resilient life.

Every responsible adult should have a plan B for heat without electricity. It can save you and your family’s life in a worst-case scenario.

There are many different options for using a heater without electricity. And we are going to cover ALL your options. Prices range from cheap to expensive – from “just warm enough to survive” to “hot enough to thrive.”

Ok, before diving into all the different non-electric heater options, you first must understand how the body generates and loses heat…

How The Body Generates/Loses Heat

Have you ever experienced a power outage in the middle of winter? It’s no summer picnic, that’s for sure. You start losing copious amounts of body heat fast through:

  • Radiation – The body naturally radiates thermal heat. And this electromagnetic radiation moves from hot to cold out of your body.
  • Respiration – The air inside your body is warm, and as you exhale, it’s lost.
  • Evaporation – As we sweat, our body’s heat is vaporized.
  • Conduction – Conduction is the heat transfer from direct contact with another object. The transfer will continue until there the two temperatures are in balance.
  • Convection – As air or water moves across our bodies, it draws warm air away, and cooler air replaces it.

Note: If your clothes are wet, the heat loss goes up exponentially. So avoid being wet, in a cold-weather emergency, which includes profuse sweating.

Ok, now that you know how your body loses heat, let’s get into the first tasks in an emergency. Reducing heat loss due to unnecessary leakage.

Reducing Heat Loss

First things first, when in a power outage, reducing heat loss is as important as gaining heat. You can’t allow heat to escape from your home and certainly not from your body.

Cracks and holes in your house are where heat escapes. And an open window is like shoveling hot coals into the snow. It’s wasted energy when you don’t have any to spare.

Go around and make your home airtight. Use towels along the bottom of doors if you have to. You must preserve any heat that you do have.

Indoor Heater That Doesn't Require Electricity

The Ultimate List Of Indoor Heaters That Don’t Require Electricity

Your Own Body

Let’s start with your meat suit.

Your body is a fantastic machine that generates heat as it operates. You need to preserve it at all costs. You also need to generate more heat.

Preserving

Before thinking of generating, persevere what you make.

Bundle up with extra layers of clothing like sweatpants, socks, and sweaters. Hats and gloves are essential too. Have extra blankets on the bed and ones for the couch. Duvets keep the heat in.

Generating

Physical activities like working out or briskly walking around can generate heat. So can frontier lifestyle activities such as chopping firewood or hauling water.

Heck, wrestling with the kids or intimacy with a partner will generate copious amounts of heat as well. Combined body heat is an effective way to share yourself by cozying up in a sleeping bag.

This works with ANYONE. But it is much less awkward with those you love (like your kids, spouse, or pet).

Just remember: Avoid working out so hard that you end up drenched in sweat. The wet body and damp clothes can quickly become counterproductive in the frigid cold.

Eating

Who’d have thought filling your face could keep you warm?

Digesting food raises your body temperature through thermogenesis. So eat foods high in carbs, protein, and healthy fats. Add some extra spice to sweat from the inside.

Hot drinks help too but need an external source of heat to make.

Sun Radiation

The sun is your friend and is among the integral alternative heat sources for power outages.

While the sun is out, take advantage of its thermal power during the day. How? By opening up curtains and blinds, so it radiates inside the home.

This is when you should charge solar-powered devices—equipment like:

While the sun is shining, open your curtains and let the sun’s rays come through your windows. It’s one FREE way to heat a room without electricity.

Another “trick’ is to fill up all your plastic water bottles and leave them in the direct light. Then bring them inside after the sun fades so they can release that heat slowly over time.

This “trick” is even more effective for larger vessels like barrels. Heck, you could even invest in a water wall that passively absorbs the heat during the day and releases it at night.

Stones can also retain the heat from the sun if they are adequately insulated. Wrap hot rocks in a towel and put them at the end of your bed to keep you warm while sleeping.

The sun is free so take full advantage of it.

Electric Lighter Used To Lite Candle Wick

Candles

Candles are natural nonelectric heaters that you can buy in bulk or make your own from your beehives. They give you two essential sources for survival; heat and light.

A candle is an essential prepper item you should add to your emergency stockpile. As well as stored in abundance at your home, bug out location, and DIY bunker.

Know this… A candle isn’t going to heat your entire house or cook a steak.

Having said that, any emergency heating is going to help. And you can light up a bunch of candles to contribute to the solution. Just be safe when using candles as they are an open flame.

Beeswax candles give off a pleasant scent and release negative ions in the room to clear the air. Lovely smells can become more important the longer you hunker down inside.

Coconut wax is a great option. It’s a highly renewable, non-toxic wax and burns cleaner and longer than other wax candles.

Tea candles are handy to stack together to form a more concentrated heat zone. And can be safely used with various holders.

You can also build your own candle heater with tea candles and a couple of clay pots.

Blankets

Blankets are a bit of a no-brainer, but most people only have one blanket per bed in their homes. This strategy is a mistake because when the power grids are down, you need extra blankets for beds, couches and to keep pets warm.

But the truth about blankets is that they don’t produce any heat by themselves. That’s your body’s job.

Instead, a good blanket will trap the heat. There are different materials used in making blankets, and the best for keeping warm are:

  • Down Filled – Mature birds have the warmest fill.
  • 100% Wool – This comes from sheep, and it’s evolved to keep them warm.
  • Fleece- Made of synthetic material to mimic wool.
  • Mylar – This is space-age aluminum and acts as a reflector for body heat.

TACT Bivvy In HandMy favorite option is the Mylar Blankets (like the Tact Bivvy).

Why? Because they are lightweight and trap nearly all the heat your body can generate. Making them more efficient than even the best fabric blanket money can buy.

I tested a TACT Bivvy Mylar blanket in frigid temps in my backyard and after only a few minutes, I was toasty warm inside.

Outside Temp / Inside Blanket

Honestly, I think EVERYONE should put a TACT Bivvy in their glove boxes for winter car emergencies.

AND they’re also a very cheap way to stay warm during a winter power outage as well!

Frozen Fingers On Cold Hands

Warmer Packs / Hand Warmers

Several manufacturers make portable body warmer packs, including:

They are great for giving you fast, long-lasting warmth.

And these devices can slip inside your gloves, in your pockets, and shoes. Or with some, you can even have adhesive to stick to your back, shoulders, or anywhere else you need them.

Different chemicals inside them react when shaken or exposed to air to produce heat. Some have iron powder or sodium acetate to make a thermal reaction. But they all are safe to use for all members of the family.

You should always have these emergency heater packs on hand. They’re crucial for outdoor winter activities and emergencies. And they’re an excellent backup if the electricity stops working in your home.

There are also portable hand warmers like the:

They can be charged and ready for use when needed.

Soap Stone

Soapstone is a natural type of metamorphic rock made primarily of talc. And people have been using it for carving material for thousands of years. Why? Because it’s relatively soft. Some grades feel like soap, and that’s how it got its name.

Besides its carving ability, soapstone is a fantastic heat retainer. It quickly absorbs heat and will radiate it back out slowly for several hours. Basalt also works similarly.

Make your own soapstone bed warmer. First, drill two holes in the top and bend some sturdy wire to make a pail-type handle.

Then you can hang it near the fire or even in a window to absorb heat during the day. At night, drag it up and down your bed and wrap it in a towel to stay at the bottom, underneath the blankets.

This setup will keep you toasty all night.

Non-electric Heater Options

If you want to heat an entire room without electricity, you’ll need something a little bigger. Several fuel-based heaters do everything from cooking to heating.

They use radiant heat or convection heat and use these different fuels:

kerosene tank

Kerosene

These heaters use kerosene liquid to heat quickly. And can provide either radiant or convection heat.

The convection type carries fuel at the base with a combustible chamber. This chamber ignites and heats in all directions through a circular design.

Radiant heaters send their heat straight out using a reflector or blower.

You can find kerosene at most home improvement stores. And they use a soaked wick with an ignition starter or a burn chamber where you use a match to light the wick.

propane tank

Propane

Propane heaters come in various sizes and use refillable tanks. They come in canister sizes ranging from16 ounces to 20-pound tanks in size.

Smaller units are better indoors and work well moving from room to room. Bigger units usually are left stationary for safety with the tank left outside.

The BLUU propane heater for outdoor and indoor use is perfect for your emergency heat.

Or this simple heater mounts to the top of a propane tank.

Check out our article Kerosene vs Propane Heaters – The Best Solution For Survival for more information.

Natural Gas

Natural gas heaters work like propane heaters. But instead of a refillable tank, you can attach the natural gas line from your home.

That is IF it’s still available in your home after a power outage.

You have to attach it to a fixed gas connection on your home. So it isn’t portable like the propane or kerosene tanks, but you do have a steady supply of fuel.

Biofuel Heaters

Biofuel is any fuel that comes from living matter. It includes wood, ethanol, methanol, biogas, and biodiesel.

They even have tabletop biogas fireplace heaters that look great and heat your space. They require you to fill up the fuel tank, and it burns for a long time without any fuss.

You can also get biofuel reusable fuel cans for portable heating on the go or in an emergency. They can heat food and provide some warmth, and they are very affordable and portable.

You can even refill them.

Every prepper should have these by the stack and in storage for an emergency.

Butane Heaters

Small portable butane heaters can get you through an emergency power grid interruption. They provide some warmth and the ability to do some rudimentary cooking.

Units like this duel butane and propane heater can provide sustainable heat indoors.

Always make sure to have a well-ventilated area when using this type of fuel.

Solar Heaters

These heaters don’t use combustible fluids. Instead, they get thermal energy from the sun. This device collects energy throughout the day and stores it until needed.

Cold air travels down into the unit and picks up the thermal heat to blow it into your room. They are expensive, but your heat is free once set up.

Fireplace and Wood Stove

Wood stoves are the perfect solution to indoor heaters that don’t require electricity. You’re in business as long as you keep your supply of dried and split wood at the ready.

A standard fireplace is best when designed into a house’s structure. And they usually require the professional skills of a bricklayer.

Proper venting, hearth, and mantel are essential components. But your fireplace will mostly radiate heat in the main room. This design is just OK tho because much air will escape out of the house and up through the chimney.

A wood stove is much better for heating!

And you can also install them during a build, but it is doable to add at a later date vs. a fireplace. It just takes a protective floor and wall solution and cutting a hole in the wall or roof to bring the stack outside.

An insulated chimney pipe passes through the framing components of a home—that way; there’s no heat touching flammable material.

A properly maintained wood burner set up can burn all night. Thus, providing all the emergency heating you need to survive without electricity.

Note: A wood stove is “THE solution” I choose for my family as a backup non electric heater!

Small Generator For Camping

Backup Generators

Emergency home heating sometimes needs a powerful generator. A large generator turns fuel and combustion into electrical current to tie into your home.

You can install large units on a concrete pad beside your home. These are ready to provide full power to run everything with the flip of a switch.

A standard “camping” gas generator can be stored until needed for smaller emergency heating. It’s easy to run a few power cords to get vital electric appliances and lights on.

You’ll need to refill with diesel, gas, natural gas, or use a solar unit.

A large solar generator is called a power station and you’ll need to pair this unit with solar panels.

Heck, you could even invest in hand crank or pedal crank generators to power a few personal items during a blackout. Plus, by cranking or pedaling, you’ll generate some of your own heat…

Check out the following articles for more information:

Wind Power

You can similarly harness the power of the wind to solar. Your wind turbine unit can store battery power and then runs some or all of your electrical needs.

If you want to use it to store power for heat, pair it with an electric heater that can plug into the battery system.

Final Thoughts

Disruption to the power grid requires planning, supplies, and equipment.

The best options include indoor heaters that don’t require electricity. Invest in these various nonelectric heater options, so you’re never left out in the cold.
