Space heater for large room with high ceilings

What are the benefits of using space heater for large room with high ceilings?

There are several benefits to using a space heater for a large room with high ceilings:

Energy efficiency:

Using a space heater to heat up a specific area of the room can be more energy-efficient than heating the entire room with a central heating system. This is because the space heater only heats up the area where it is placed, which can save energy and reduce heating costs.

Faster heating:

Space heaters can heat up a room much faster than central heating systems, which can be especially beneficial for large rooms with high ceilings that can take longer to warm up.


Space heaters are portable and can be moved from one room to another, making them a flexible and portable heating solution for homes or offices with multiple rooms.


Space heaters can be a cost-effective solution for heating specific areas of a large room, as they are generally more affordable than installing a new central heating system or upgrading an existing one.


A space heater can provide localized warmth, making it more comfortable for people who are sitting or working in a specific area of the room. This can be especially beneficial in large rooms with high ceilings, where the air near the ceiling may be cooler than the air near the floor.

To conclude, it’s important to keep in mind that space heaters should be used safely and according to manufacturer’s instructions, and should never be left unattended or placed near flammable materials.

What kind of a space heater is preferred for a large room with high ceilings?

When it comes to heating a large room with high ceilings, a space heater with high heating capacity is preferred.

Look for heaters that have at least 5,000 BTUs (British Thermal Units) or more, as this will provide enough heat to warm up the room effectively.

In addition to heating capacity, it’s also important to consider the type of space heater. 

Fan-forced heaters: These heaters use a fan to distribute heat evenly throughout the room. They are typically more affordable than other types of heaters and can be effective for heating large spaces.

Radiant heaters: These heaters use infrared radiation to heat up objects in the room, which then radiate heat back into the space. They are typically more energy-efficient than fan-forced heaters, but may take longer to warm up the room.

Oil-filled heaters: These heaters use electricity to heat up oil that is sealed inside the unit. They are typically slower to warm up, but can provide long-lasting heat and are relatively quiet.

Regardless of the type of space heater you choose, be sure to follow safety guidelines when using it, such as keeping it away from flammable materials and never leaving it unattended.

How to choose the best space heater for large room with high ceilings?

When it comes to heating a large room with high ceilings, choosing the right space heater is crucial to ensure that your space stays warm and comfortable.

Here is a buying guide to help you choose the best space heater for your needs:

Consider the size of your room:

When selecting a space heater, it’s important to choose one that is powerful enough to heat your entire room. For a large room with high ceilings, you’ll need a heater with a high wattage rating to ensure that it can adequately heat the space.

Choose the right type of heater:

There are several types of space heaters available, including radiant, convection, and fan-forced heaters.

Radiant heaters are ideal for large rooms with high ceilings as they emit heat directly, which can help to warm up the space quickly.

Convection heaters are also a good option for large rooms as they use natural air circulation to heat the room.

Fan-forced heaters are another option, but they can be noisy and may not be as effective in large spaces.

Look for safety features:

When using a space heater, safety should always be a top priority. Look for heaters with safety features such as automatic shut-off switches, overheat protection, and tip-over protection to ensure that your heater won’t cause any accidents or damage.

Consider energy efficiency:

Space heaters can be energy-intensive, so it’s important to choose one that is energy-efficient. Look for heaters with energy-saving features such as programmable thermostats and timers, which can help to reduce your energy consumption and save you money on your energy bills.

Check the noise level:

Some space heaters can be quite noisy, which can be distracting and unpleasant. Look for heaters that operate quietly, e.g. infrared heaters, so that you can enjoy a peaceful, comfortable environment.

Read reviews and compare prices:

Before making a final decision, read reviews from other customers to get an idea of the heater’s performance and reliability. Compare prices from different retailers to ensure that you’re getting the best deal.

Some recommended space heaters for large rooms with high ceilings are the Dr. Infrared Heater Portable Space Heater, Duraflame Electric Infrared Quartz Fireplace Stove, and Lasko 755320 Ceramic Space Heater.

Ultimately, the best space heater for your needs will depend on your personal preferences and the specific requirements of your space.

By considering these factors and doing your research, you can choose a space heater that will keep you warm and comfortable all winter long.
