Using an Oven to Heat the House is a Bad Idea

As the colder months approach, some people wonder if they can use their oven as a source of heat for their home.

It’s tempting to think that an appliance designed to generate heat could double as a makeshift heater during chilly days.

While this idea may seem practical on the surface, there are several reasons why it’s not recommended.

While turning on your oven for a quick burst of warmth might be tempting, it’s important to know that using an oven to heat your home can be dangerous. This is especially true for gas ovens, as they can release harmful carbon monoxide into your living space. Even if you have an electric oven, there are still safety concerns and inefficiency issues to consider.

Can I Use My Oven to Heat My House?

According to consumer reports, using your oven to heat your house is not a safe or recommended practice. There are several risks and dangers associated with this method.

Electric ovens and gas ovens function differently when it comes to generating heat.

Electric ovens use heating elements to create heat, while gas ovens rely on igniting flammable gas to produce heat.

Consequently, each type of oven carries unique hazards when used as a heat source.

Using a gas oven to heat your home can be dangerous due to the risk of carbon monoxide poisoning.

Carbon monoxide (CO) is a colorless, odorless, and tasteless gas. Since it cannot be detected by human senses, it can build up in your home without you realizing it and lead to fatal consequences.

Additionally, using a gas oven for heat can increase the risk of fire.

On the other hand, electric ovens do not pose the same risk of carbon monoxide poisoning.

While they may seem like a safer option, using an electric oven to heat your home is still inefficient and can increase your energy consumption significantly.

Moreover, the high oven temperatures can also pose a risk of burns and fire.

It is essential to keep in mind that ovens, whether gas or electric, are designed to be used as kitchen appliances for cooking, not as a primary source of heat.

Relying on your oven for heat can result in overuse and decreased lifespan of the appliance. It can also lead to uneven heating, as the oven will not distribute heat evenly throughout your home.

In essence, using your oven to heat your home is not recommended due to several safety concerns and inefficiencies.

Instead, consider investing in a proper heating system, such as a furnace or space heater, designed to distribute heat evenly and safely throughout your home.

If you are experiencing difficulties with your existing heating system, it’s best to consult with a professional to find the most effective solution for your needs.

Dangers of Using Oven to Heat the House

Let us now look at the dangers of using an oven to heat the house

Carbon Monoxide Poisoning

One significant risk of using a gas oven to heat your home is carbon monoxide poisoning

Carbon monoxide is a dangerous, odorless gas that can lead to severe health issues or even death if exposed to high levels over time. 

When you use fuel-burning appliances, such as gas ovens, correctly, they should not pose a significant risk of carbon monoxide production. However, using a gas oven to heat your home can cause an unsafe buildup of CO, and it is not recommended.

Even small increases in CO air concentration levels can be hazardous to your health over time.

Exposure to high levels of carbon monoxide can result in symptoms such as headaches, dizziness, vomiting, and confusion. In extreme cases, it can be fatal.

To prevent carbon monoxide poisoning, always use appliances according to their intended purpose. Make sure to keep your oven and other fuel-burning equipment well-maintained, and never rely on them as a primary source of heat.

Ensure proper ventilation in your home, and of course, avoid using gas ovens (or any ovens for that matter) for heating.

Risk of Fire

There’s also an increased risk of fire when using an oven to heat your house. 

Ovens are designed for cooking, not heating. Leaving them on for extended periods can cause overheating, malfunction, and potentially start a fire. 

Risk of Burns

Using an oven to heat your home puts you and your family at a greater risk of burns.

Ovens become extremely hot, and accidentally touching them can cause severe burns. 


Heating your home with an oven can be expensive.

Ovens, especially gas ones, are not energy-efficient when used for heating purposes, leading to increased utility bills.

Risk for Asthma, Chronic Respiratory Patients

Heating your home with a gas oven can negatively impact indoor air quality, causing issues for individuals with asthma, chronic respiratory problems, or weakened immune systems.

How to Heat the House in Winters Properly?

 Here are all the right ways to heat the house in winter: 

Heating System

One effective way to stay warm is by investing in a good quality heating system.

Furnaces and central heating systems provide warmth that can efficiently heat your house. 

Don’t forget to install carbon monoxide detectors, as furnaces work overtime in winter.

When your furnace is not available, space heaters are a popular alternative for heating your home. There are many options available, such as portable electric, propane, or oil-filled heaters. 

Always follow the manufacturer’s safety guidelines and keep heaters a safe distance from flammable materials.

Insulation and Sealing

Insulation plays a crucial role in maintaining warmth indoors. 

Check your windows for drafts and seal any gaps with a weatherstripping or insulating film. Make sure your attic and walls are properly insulated.

Use draft stoppers or rolled-up towels to block cold air from entering through the gap at the bottom of your doors.

Introduce insulated area rugs or carpets to your rooms with hardwood or tile floors to provide an added layer of warmth underfoot.

Extra Blankets and Sleeping Bags

Having a supply of extra blankets, quilts, or sleeping bags can be very helpful in an emergency when you need to conserve heat and keep your family warm.

Make sure these items are easily accessible and stored in a dry location.

Keep the Door Closed and Hang Heavy Draperies

Closing interior doors can help maintain warmth in individual rooms.

Also, using heavy drapes/thermal curtains can block drafts and create an additional layer of insulation on windows. 

This can be effective in reducing heat loss, especially when there is a power outage or issues with your heating system.

Rearrange Your Furniture

Arrange your furniture to maximize heat circulation.

Place sofas and beds away from exterior walls, and if possible, position them near heat sources.
