A Heater Without Electricity – Exactly How Does That Work?

Heater without Electricity

Yes, there are heaters that work without electricity! These types of heaters are often referred to as “fuel-fired” or “solid-fueled” heaters. These are the types of heaters that work using wood, propane gas, or kerosene.

These heaters are great for providing supplemental heat or even primary heat depending on the situation, but they do require fuel in order to operate.

When choosing a heater that works without electricity, it is important to understand how the fuel they use actually heats up the home. Before we continue, it is important that your home has proper ventilation. Without proper ventilation, fuel-fired heaters can be very harmful to the air quality in your home.

Fuel-fires and solid-fueled heaters work by burning the fuel completely. The energy produced from this complete combustion heats up a grate, which in turn heats the surrounding air. Since these heaters use fuel, they are generally portable. This means you can move them to different locations around the house as needed.

Generally, you will need to refuel these heaters regularly throughout the day. They work great for supplemental heating, but they will ultimately have to be shut down and refueled in order to avoid carbon monoxide poisoning.

What are Non-Electric Space Heaters?

Non-electric space heaters are also called fuel-fired heaters, combustion heaters or solid-fueled heaters. These types of heaters are the only heat source in houses without electricity. Other sources of heat include wood stoves, generators and campfires.

Non-electric space heaters can be grouped into portable and stationary. Portable versions of these heaters are also called fan-assisted or radiant heaters, while the stationary models are often called kerosene heaters, gas heaters or wood stoves.

Different Types of Non-Electric Space Heaters

Radiant heaters

These heaters are made of insulated metal or ceramic plates that allow the heat to be conducted directly into the room. This type of heater may be more suitable for smaller rooms.

Forced-air heaters

This type of heater uses a fan to blow air into the room with the help of a duct system. Forced-air heaters are suitable for medium to large rooms, but they can be very expensive to run because you need a large furnace capable of handling the air flow.

Convection heaters

This type of heater has metal fins that you can adjust to point toward the ceiling or directly into the room. This allows for more targeted heating of the area where people are located.


These heaters are usually made of cast iron or sheet steel. They are large and bulky, but they spread the heat very evenly because the metal slowly heats up. You can expect to spend a lot of money using this type of heater because it is usually gas-powered.

The main difference between these heaters is the type of fuel they use. Kerosene heaters, gas heaters and wood stoves usually require a lot of work to run, but they can save you a lot of money in heating bills.

Propane vs Kerosene Heaters

The main difference between propane and kerosene heaters is in the fuel they use. Some of these heaters are also called LPG heaters because they can be powered with liquefied petroleum gas.

Propane heaters

This type of heater uses propane gas, which is usually made from natural gas or oil. You can find these heaters in the portable, radiant and forced-air models. The best thing about propane heaters is that they are very cheap to run because you only need a small propane tank.

Kerosene heaters

This type of heater uses kerosene, which can be made from wood or oil. Since kerosene is more expensive than propane, kerosene heaters often require a lot of fuel to run. You can find these heaters in the portable and convection models.

Watch out for Ventless or Vent-free Portable Gas Heaters

Beware: Ventless gas heaters are very hazardous. They draw air from inside a room to feed the combustion of fuel and release carbon monoxide back into same room, making them risky for use indoors due lack in oxygen or suffocation risks like any other fire does (with insufficient ventilation). It’s also illegal in many states including Massachusetts and California.

Pros and Cons of Non-Electric Space Heaters

There are several advantages and disadvantages of using non-electric space heaters.

On the one hand, these heaters allow you to keep your house warm throughout the cold season without needing a permanent source of electricity. Non-electric heaters can be more economical than electric heaters because you don’t have to pay for fuel.

On the other hand, these heaters can be very expensive to use for heating large areas. The other downside is that non-electric heaters are generally less safe than electric ones because they contain fire or burned fuel.

Final thoughts

The final thought is that if you are looking for a way to keep your house warm during the winter season without needing electricity, consider using non-electric space heaters. However, be careful of ventless or vent free gas heaters because they can lead to suffocation risks and carbon monoxide poisoning.

Remember that you can always consult a professional building engineer with any questions or concerns.
