How to Heat a Cold Basement Efficiently

In a modern-day home, a basement is rarely used as a storage space. Currently, many dwellings have basements that are designed as living spaces. However, most homes have cold basements, and as winter sets in, these drafty and cold basements become inhabitable. You might ask yourself: how to heat a cold basement efficiently?

If you are thinking of utilizing your basement as an extra room, a kids’ play area, theater, or a gym, it’s time to invest in some easy and affordable heating options. Here is how you successfully and efficiently heat a cold basement! 

Why Are Basements Cold?

All basements, no matter where you live, are colder than the other floors in your home; ever wondered why that is? Well, there are several reasons why.

1. Ground Chill

Most basements trap the cool air and recirculate as undergrounds are much colder than above the ground floors. 

2. Moisture

Another reason for the cold basement is trapped moisture. The excess moisture can make the air damp permanently, making your basement feel chilly all the time. Did you know that in America more than 60% home basements suffer from moisture (source)?

3. Heat Rises

Science tells us that warm air is lighter than cold air and therefore, the heat rises. That means that the heat from the basement travels to the above floors while the cold air travels downwards towards the basement. This phenomenon makes your basement chilly.

Why Basement Heating Is Important

There is a reason why people extend their ducting system to warm up their basement. A cold basement affects the overall temperature of the house, hence affecting the heating bills as well.

A warm and habitable basement can turn into a perfect additional living space. You can convert this space into your studio, a gym, or even a playroom for the kids. 

Making use of a heated basement as extra living space

Here are some of the best methods you can use to warm up your basement and keep your home warm and toasty during brutal winters.

1. Infrared Space Heater

8 Cheap Ways To Heat A Cold Basement Efficiently

Apart from using heating gadgets, you can also check out the following efficient and low-cost tips to warm up your basement. While heaters and other gadgets work, they won’t be efficient if there are underlying problems. Cold drafts seeping in, windows with gaps, and cold flooring will always kill the heat quicker, keeping your basement ultimately cold.

1. Drafty Windows And Gaps

It’s safe to say that in most dwelling spaces, the basement is the one we least bother with. Because it usually is not a living space, most basements are not properly done as the rest of the house. There might be gaps and old windows letting in cold air.

These drafty windows and cracks should be properly sealed as they keep the room from getting warm, even with proper insulation. Sealing windows is easy and not as costly as most heating gadgets; you can use either caulk or a DIY window insulator kit to seal drafty windows and stop cold air from penetrating your basement. 

Another simple yet effective gadget is a ‘draft stopper’. Use draft stoppers on doors and windows to seal gaps that may let in the cold air from outside. These small cracks may just be the biggest reason why your basement feels chilly all the time, especially during cold winters. 

The plumbing system also runs through the basement to the rest of the house; sealing the corners of these pipes and walls with foam will also help with heat escaping.

2. Properly Insulate First-Story Walls

Now, according to science, the hot air rises up, and the cold air settles down. By this logic, if your first floor is not adequately insulated, it will act as an outlet to descend the cold air into the basement. Identifying where the draft is coming from will help you solve the problem sooner than later. 

3. Vent Flaps

Most furnished homes come with basements that are equipped with vent flaps. However, cheap vent flaps are inadequate in preventing cold air from coming in. With such vent flaps, it will be hard to warm up the basement no matter what you do. Investing in better vents like ‘floating shuttle’ will help you keep your basement warm and also help you reduce your energy costs. 

4. Properly Insulating Basement Ducts

Ducts are the primary culprits for getting the cold air in: through a small opening, the cold air shoots in with a lot of pressure. If you have bathroom ducts or dryer ducts in your basement, your basement will feel like Siberia as such ducts are no less than pipes of thin aluminum or paper-thin plastic. These provide no insulation. In fact, they make the place even colder. The most cost-effective way is to wrap such ducts with insulation. 

5. Use Thermal Camera to Locate Cold Spots

You can either buy a thermal camera or lease one from a rental center and use the technology to locate cold spots in your basement. This can be done to both furnished and unfurnished basements. With an excellent powerful thermal camera, all you need to do is stand in the middle of the room and point the camera in various spots to learn where the energy losses are occurring the most. With cold spots detected, you can fix those areas to conserve energy and warm up your basement. 

6. Install Carpets and Rugs

Making a place cozy doesn’t mean you have to spend a lot of money: with simple tips and tricks, you can make a huge difference. Did you know that 13% energy loss occurs through floors? And if you insulate the flooring, you are most likely to conserve heat. Most basements have stone or concrete flooring, and no matter what you do, such flooring will always be cold to touch.

Wall-to-wall carpeting is a great idea to minimize heat loss. With the help of rugs or thick shag, you can increase the distance between floor and feet hence keeping the cold away from your body. 
Pro tip: thick woolen carpets work better than any other kind.

7. Replace Windows

Just like the flooring, a lot of heat is lost because of single-glazed windows. Around 48% of the basement heat is lost due to window glass. Replacing your windows or blocking them with 99% tint might solve more than half of your problems.

However, having 99% tinted windows can make your basement look gloomy and claustrophobic. Switch to double-glazing or triple-glazing glass for your windows. Such windows are most effective for insulation and preventing heat loss while also letting sunshine into your basement.

Apart from that, one-way reflection windows are also great and cost-effective as they keep out 91% of solar rays but still allow maximum light penetration.

8. Curtains And Cellular Shades

A cozy basement is all you need to spend your winters in comfort, however, heating the basement can be very costly. Therefore, we advise investing in heavy shades. Install heavy curtains or cellular shades to add layers.

You can open up the curtains in the daytime, let the sun fill the room and make it warm. And by dusk, close the curtains and enjoy the conserved heat while sipping a large mug of hot chocolate. You can eliminate 80% of heat transfer through heavy curtains and cellular shades to save energy.

Spend your winters with your family in a toasty atmosphere without worrying about the utility bills!
