Best Space Heater For Large Basement

Winter is here, which means one thing for most areas – extreme cold in the home and even colder conditions in the basement.

So, many people will be thinking about ways to heat the basement. A few are already ordering baseboard heaters and radiant heat flooring.

Both of these are excellent heat sources in the basement. Some are also thinking about more portable heating options, including space heaters, stoves, and fireplaces.

The choice is yours. But, if you’re still in the “planning” phase, we think you should consider portable heaters. Read on to learn why and how to pick the best portable heater for the basement.

k from the above list. We’ve keenly evaluated all five heaters and can verify that they are some of the best for basement heating.

However, if you have time (we hope you do), it’s always nice to learn more about basement heating and basement heaters so you can make an informed choice when you’re ready to buy. The following are some of the things you want to know about as you head out shopping.

Benefits of Heating the Basement

A basement is typically a cold place, even during the warmer months. According to multiple studies, internal ground temperatures tend to be consistent at 55°F (13°C) both in the summer and winter.

However, as the freezing temperatures engulf the home during winter, the basement may become colder as temperatures in the main home drop.

Heating the basement, alongside the rest of the home, when the temperatures drop below 16°C is a good idea for the following reasons;

  • Prevent heat loss: This is, by far, the biggest reason why you need to heat the basement in the summer. Although warm air rises, the basement can still cause a big drop in your heating efficiency. Indeed, some studies suggest that the basement accounts for 20% of the home’s heat loss in the winter.
  • Prevent draft: You don’t want a situation where you occasionally experience a dash of cold air blowing through your home from the basement, do you? If so, heating the basement is a must. Otherwise, prepare to battle the cold drafts every few days.
  • Reclaim underused basement: Many people avoid or underutilize the basement because of poor climatic conditions. Basement heating also allows you to make better use of the basement around the year. You can even turn it into a home office or your private library once there’s sufficient heating and air conditioning.
  • Prevent mold and mildew: The poor air conditions in an ill-maintained basement can quickly create the perfect mold and mildew conditions. These microorganisms are linked to several health issues, including allergies and asthma. They can also cause respiratory tract and lung issues. 

What Temperature Should I Keep My Basement in the Winter?

General recommendations for winter thermostat setting are 72°F (22°C) to 68°F (20°C) if someone is in the home in the daytime and 66°F (19°C) to 62°F (17°C) if everyone is away during the day or hen you’re asleep at night.

For the basement, it would be advisable to go with the latter settings (66°F to 62°F) when you’re not using the area and the standard 72°F to 68°F when using the space. Remember that you need the right temperatures for your body to function normally.

What’s the Best Type of Heater for the Basement?

You can always extend the furnace ductwork to heat the basement. This allows you to heat the entire home from a single source. However, not many families have taken up this option for various reasons.

Under such circumstances, the best solution to basement heating becomes portable basement heaters. Fortunately, there are several portable basement heating solutions to consider. The four main options are as follows;

Baseboard Heaters

There are two types of baseboard heaters – electric and hot water. For the basement, electric baseboard heaters are the better choice.

These heaters use electric resistance. Cables inside the heating unit warm the air, pushing it out of the unit. Simultaneously, cold air enters the unit from the bottom to be heated.

A thermostat continuously tracks heating levels in the room. Once the air entering the baseboard reaches the thermostat setting, the baseboard heater turns off until it’s needed again.

Baseboard heaters are one of the best ways to heat rooms individually, especially rarely used spaces. They are also very efficient.

Portable Space Heaters

Portable space heaters are heating units that you can carry from one room to the next with ease. Many of them even have handles for easy mobility.

Most space heaters are electric-powered, though a reasonably large number run on propane. Some are also powered by kerosene and oils. They are typically powerful enough to warm even a large basement.

Gas and kerosene models are especially very powerful, with some rated at 60,000 BTU or higher. The propane and kerosene models are typically set on the floor or a unique stand, while most electric models hang on the wall or ceiling.

Space heaters stand out for their versatility. Your basement space heater can be used in many other settings, including camps, RVs, etc.

Stoves and Fireplaces

Stoves and fireplaces are other excellent choices for basement heating because these two add something other heaters don’t have – ambiance!

Stoves for the basement can be wood-burning or gas-powered. Many people prefer wood-burning units because of the extra charm. However, you must be ready to source dry wood and clean the stove often.

Fireplaces are another excellent choice, though they are less potent than stoves (the standard wood stove is 3x more powerful than the average fireplace).

Whichever option you choose, remember that these two options come with substantial maintenance requirements, unless you opt for electric fireplaces.

Radiant Floor Heaters

Finally, radiant heat flooring systems supply heat directly to the floor or panels in the room’s wall or ceiling.

They are called radiant heaters because the transfer of heat is by radiation rather than convection. In radiant heating, heat is delivered directly from the hot surface to the people and objects in the room via infrared rays. When the heat source is located under the floor, the setup is called radiant heat flooring.

Radiant heat flooring is the most efficient solution on this list – even more efficient than baseboard heaters. It also doesn’t disturb air and allergens like forced-air systems. The units can be hydronic (water-based) or air-heated, or electric.

Frequently Asked Questions

  • Propane vs. Natural Gas vs. Electric Baseboard Heaters, Which is Better? All three have their pros and cons. Most people prefer baseboard heaters because they are easy to install and use. They are also extremely efficient. However, propane and natural gas heaters are more powerful.
  • What’s the Best Size Space Heater for the Basement? It depends on the heater type you choose. You need 10 watts per square foot for baseboards and other electric heaters, thus 4,000 watts for a 400 square-foot basement. If you prefer fuel heaters, you need about 25 BTU per square foot.
  • How Do I Prevent Heat Loss in the Basement? Through insulation. The basement is one of the least insulated areas in the home. Consider foam insulation, spray foam insulation, and batt insulation.
