How To Warm Up A Basement

To save money on heating bills, you must make it a priority to warm up your cold basement. Cold basements reaching 40–50 degrees Fahrenheit suck the warmth from the rest of the house.

Before you start heating your basement, you must find out how the cold is getting in. Arm yourself with a thermal camera and go around the basement to locate the cold spots.

After pinpointing the problem, use either of the following suggestions to rectify it and get rid of the cold. Then you can do the following:

Insulate The Basement

A basement is partially or completely buried in the ground, and it gets little to no natural heat from the sun during the day. Therefore you have to heat it artificially.

When you complete construction, ensure that you insulate the type of basement that you have as much as possible. Use heat-retaining construction materials on the basement walls and floor.

Insulate The First Story Properly

To stop the heat from escaping, see to it that the first story is well insulated too. Technically speaking, the first story floor is the basement's ceiling.

It will reduce your energy bills because you will use less heat to keep the first story and basement well heated.

Seal Off Drafty Windows And Doors

The cold draft can easily find its way into any room when the windows aren't sealed properly. In basements, ensure that the windows are well-sealed, especially in the winter months.

Keep Heaters And Radiators Clear

After sealing the windows and doors, turn on the heaters and radiators during the colder months of the year. Since radiators and heaters are often located at the bottom of windows, ensure that the curtains aren't covering them.

Move the furniture away from the radiators and heaters to allow warm airflow. Avoid putting wet clothes to dry on heaters and radiators.

Install Quality Vent Flaps

Ventilation is key in any basement and the home in general. Therefore, purchase quality vents for your basement that will function properly.

Poor ventilation keeps the moist damp air in the basement making it colder than necessary. Keep the vents clean and clear of any dust to avoid getting hay fever when in the basement.

Warm The Foyer

You can warm the foyer that leads to your basement in the cold months. Use tiles that retain heat or floor heating. You could also put a radiator or heater to warm any cold wind coming from the outdoors. This will help keep the heat inside and reduce the power bills.

Invest In A Fireplace

As a homeowner, you should invest in a fireplace. Depending on your basement, choose and install a fireplace that will keep the basement warm. There are a variety of fireplaces in the market.

Install an open or closed, coal or electric fireplace with the help of a professional in your basement. A professional will consider the ventilation of the basement before picking a suitable fireplace.

Decorating With Warm Colors/Shades

To make your basement feel warm and cozy, you should decorate it with the appropriate colors and shades. Paint the basement walls with shades of cream whites, warm yellows, or blues.

Throw pillows, rugs, carpets, and blankets of warm or brighter colors and shades will create the necessary ambiance. Have bright accent accessories such as paintings, vases, or photos in the room.

Lots of lighting will brighten the room in the absence of wide windows. Free-standing lamps, wall sconces, and ceiling lights will do the trick.

Drafts from windows and doors in a walkout can be a menace in the basement. The cold never leaves the basement no matter how much you heat it.
