Choosing the Best Space Heater for Large Room with High Ceilings 

Type of Heating Systems for Large Rooms

The heating system is an important factor that you should consider when buying a space heater for rooms with high ceilings. This is the case because the type of heating system determines how effectively the heater warms your room.

Also, the heating system type plays a key role in determining the level of efficiency of your heater. The level of efficiency is how well a heater consumes energy to warm your room.

Two main heating systems are used in heaters: infrared and convective.

Infrared Heating

Infrared heaters deliver infrared radiation to physical objects within the room. The objects include walls, furniture, and even the floor. When the objects absorb the infrared radiation, they start releasing the heat to the air within the room.

The infrared radiation type of heating is very efficient. On the one hand, heaters that work using this system tend to provide warmth in large rooms very fast. The heating of inanimate objects within a space takes place instantly, thus creating a perfect solution for rooms with high ceilings.

Additionally, infrared heaters are good for large spaces with high ceilings because they help to provide a steady source of heat for a long time.

Heating such spaces are always difficult because of the massive temperature differences between the floor and the roof. However, infrared heaters can effectively provide the much-needed heat for a long time.

Convective Heating

Convective heaters work by warming the air that comes into contact with the heating element. The heaters have a glowing element that repeatedly heats the air currents that flow across it. As the air currents get heated, they rise and immediately get replaced by cool air currents. The process repeats as long as the heater is on.

Convection heaters are not ideal for heating large spaces with high ceilings. Although naturally, warm air rises and is replaced by cool air, this process is not effective enough to counter the high-temperature gradient that is usually a permanent feature in large spaces with high ceilings.

The circular flow of air that is created by convective heaters may be ideal for warming small places with standard or even low ceilings. Also, because this type of heater relies on effective airflow, it has to be placed near natural openings in a building for it to be efficient.

If you keep many natural apertures in a large room with a high ceiling, open for long, you may not achieve the ideal ambient temperature easily.

The Goal of Heating Large Spaces with High Ceilings

To determine the heating requirements of a large room with high ceilings, it is necessary to consider a few important factors. First, the difference in temperature between the outdoor air and room air determines the amount of energy that you need to spend to keep the space warm.

The temperature of outdoor air is subject to changes in the weather and the location of your house. Outdoor temperature dips when in the winter and rises steadily during the summer.

Also, the temperature fluctuates across the day and night. This is largely beyond your control; however, it affects the amount of energy that you end up spending on your house.

The temperature within the room should be maintained within an acceptable range. This largely depends on your preferences and the prevailing conditions outside.

When the difference between the outdoor and indoor air temperature is high, then you will require to utilize a lot of energy to keep the inside of the room cozy.

If the difference in temperature between the outdoor and indoor air is low, then your energy expenditure will decrease. This factor determines the kind of heater that you may need to warm your house.

When the fluctuations are high, using a heater that has high heating capacity but standard power consumption rates may be the right thing to do.

Heating Capacity and Controls

The heating capacity of your heater determines how well it can generate warmth in large spaces. Ideally, you can toggle between the high and low heating capacity modes depending on your energy requirements. At high capacity mode, heaters consume 1,500w while at low heating mode, they utilize 750w.

Additionally, heaters have numerous controls that you can use to adjust their performance. Some electric fireplaces have up to five settings for heating temperature and color of the flames.

The higher the level of control, the better it is to use the heater to warm your rooms. This is so because you can adjust the heater based on prevailing indoor and outdoor weather conditions.

Zone Heating

Not all the areas in a large room with high ceilings need to be warmed evenly. Ideally, maintain a uniform temperature within the living zone and in the zones where people spend the most time in.

Attempting to achieve and maintain uniform temperature across the entire space that has a large ceiling may cause your energy bill to shoot through the roof.

Infrared heaters may be used to provide warmth in areas where the heat is needed most at any given time. Even heaters that have little capacity may be effectively used to provide warmth in large spaces if you use their controls properly.

Low-Temperature Gradient

The temperature gradient of a room refers to the difference in warmth between the ground and the ceiling. This difference is of great significance in houses that have high ceilings. Big differences in the temperature between the ground and the ceiling make the dwelling zone of a house uncomfortable.

To address this problem, use infrared heaters. The infrared rays directly warm objects in the house within a few seconds of setting the heater on.

The inanimate objects then steadily release heat to the atmosphere. Thanks to this mode of operation, using such heaters for high-ceiling places reduces the temperature gradient very significantly.

Moreover, when you use infrared heaters in spaces with high ceilings, you overcome the danger of overheating. Conventional heaters are known to easily create overheating problems when they are let to run for a long time.

However, using infrared heaters helps to reduce the temperature gradient to an unnoticeable level and eliminates the danger of overheating.

Last Words

While you can use a space heater to heat a large room with high ceilings, you have to be cautious about how you use it. Don’t make it your primary heating system and you won’t have to worry about your heating bills. Make it your central heating system and you’ll have to be ready for higher heating costs.

This review of the best space heater for large room with high ceilings is only to help you narrow down your search to products that will provide the necessary warmth so you don’t die in the cold. However, there are other products that you can choose.

If you’re still not sure, go for Dr Infrared Heater because it’s less expensive and can heat up to 1000 square feet.
