Why are High Ceilings Harder to Heat Compared to Standard-Height Rooms?

Most people consider high ceilings as elegant and classic. They make a room/home feel bigger thanks to the extra space.

But then, with the extra space, high ceilings cost more to heat compared to standard-height rooms.

You see, since heat rises, the ceiling heats up faster, while the area closer to the ground takes longer to become warm enough. While you can install a ceiling fan to push the warm air down, you’re better off investing in a quality space heater that can quickly and evenly heat up your large room with a high ceiling.

In this post, we review the 5 best space heaters for large rooms with high ceilings. Our review also includes a comprehensive buyer’s guide and tips on how to choose the perfect space heater for your high ceilings. Our review also aims to help you choose a space heater that will heat the air more efficiently to save on energy bills, and one that is safe to touch, and of course, budget-friendly.

Things to Bear in Mind When Choosing the Best Space Heater for a Large Room with High Ceilings

Space heaters provide a convenient way to quickly raise the room’s temperature and add some warmth during chilly nights and those harsh winter months.

Most models are portable, which means you can easily heat just one room instead of the entire house. This of course helps to reduce heating costs.

They also come in a variety of sizes, designs, cost, and a wide array of features and this allows consumers to choose those that suit their home heating needs.

That being said, before you whip out your wallet and make the purchase, there are a few important things you should bear in mind. Like I stated earlier, there are literally tens if not hundreds of space heater brands, and choosing the right one can be a daunting task.

This is especially so if you’re looking for a space heater for your large room with high ceilings. This article discusses 6 most important things to consider before buying a space heater for your large room with a high ceiling.

1. Room Size

The size of the space heater should be in accordance with your room size to ensure efficient heating. In the case of a larger room with a high ceiling, a bigger space heater would do much better compared to a small heater.  As a general rule of thumb, a space heater will use approximately 10 Watts to heat each square foot of your room. For example, a 1500 Watts space heater will cover spaces as large as 150 square feet. However, some models with advanced heating technology will heat up more space, even up to 800 square feet or more.

2. Type of Heater

There are 3 main types of space heaters: Radiant, Convection, and Combination heaters.

  • Radiant space heaters are a great choice if you want to get warm faster. Rather than heating the surrounding air, radiant heaters heat the people and objects in the room. So if you have a large room with a high ceiling, you don’t have to wait for the huge space to heat up. These types of heaters are also referred to as Infrared Heaters as they use infrared heating technology to heat up objects in the room.
  • Convection Space Heaters-Unlike radiant heaters, convection heaters heat the air in a room, not the people or objects. Instead, the heaters emit hot air that rises to the ceiling. The cooler air in the ceiling is then pushed towards the ground, allowing for even distribution of heat in the room. This is one reason that makes it a great choice for rooms with higher ceilings. Common types of convection space heaters include Oil-filled heaters, water-filled heaters, and baseboard heaters.
  • Combination Heaters-Combination heaters are a little bit different from both convection and radiant space heaters. This is because they use a fan to distribute warm air throughout the room.

3. Space Heater Design/Style

Space heaters come in a wide array of styles and designs. They include;

  • Wall heaters which can be installed on the wall in any part of the room/house
  • Floor heaters which are portable and compact and can be easily placed on the floor in the living room, bedroom, or even baby nursery
  • Baseboard heaters heat the air close to the ground which then rises and naturally circulates in the house/room. They are highly energy-efficient, require less space, are quiet, and very safe
  • Space heaters- These will keep you warm and comfy as their sole purpose is to warm the surrounding objects and people

4. Energy Efficiency

One of the biggest drawbacks of heating your home is that space heaters can easily skyrocket your energy bills. If you want to keep your heating costs low, you’ll want to find an energy-efficient space heater. In this case, you need to check for special features like low wattage, programmable timers to ensure minimal power usage, adjustable thermostats, energy-saving features, and more.

5. Safety

Portable space heaters can quickly become a fire hazard if not properly handled or carefully monitored. Some older models overheat even on the surface and therefore become too hot to touch. They can become a health hazard for you, your baby, and even pets.

Thankfully, most modern models are carefully designed with safety features that reduce the risk of fires and burns. Most of these models come with Cool-to-touch surfaces, making them safe to touch. Others have Tip-Over Protection which includes an automatic internal switch that automatically shuts off when the space heater is accidentally knocked over or tipped over. This prevents potential fire hazards.

6. Noise Level

Nobody wants a noisy space heater. The good news is that most modern models are generally quiet or basically produce less noise compared to others, especially those fan-forced heaters. Be sure to check the noise level of the space heater you’re buying,
