When choosing an electric space heater for a large room with vaulted ceilings, it’s important to remember that these heaters are usually best as a secondary heat source, not the main one. Space heaters can use different methods like convection or radiant heating to warm the air. They are typically powered by electricity, gas, or heating oil. Look for heaters with qualities like quiet operation and an adjustable thermostat.

If you’re feeling overwhelmed by the options in the market, don’t worry, I’m here to help. When searching for the most energy-efficient heater for a large space, consider a few key points. First, decide between a fan heater, which circulates warm air, and a radiant heater, which directly warms objects and people.

Dr. Heater gives out 60% more heat than other 1500-watt heaters. Just because two heaters have the same heating power in watt does not mean they produce and circulate the same amount of heat. Wattage means the amount of electricity needed to power the heater and not the amount of heat it can deliver.

Dr.Infrared Heater’s advanced optimal heating system enables greater heat production without using any more power with a high-efficiency blower that delivers an average of 250°F at 3.5m/s to your room versus competing heaters that can do only 155°F at 2.2m/s.

How to Pick the Best Electric Heater for a Room with High Ceilings

Physical Size

When purchasing electric heaters, you should go for one of a medium sized unit with a portable size. You should be considering this since your room is made of a high or vaulted ceiling, small sized heaters would not efficiently perform when placed in the room.

The larger the heater, the more efficiently it would heat up to the upper part of the room. If you are concerned about the size and portability, you should go for a moderately portable heater which should have at least a rating of 1500 watts.

For mobility sake, Medium sized heaters are still easily movable in case you need to take it to another room so far it is not mounted on a wall.

Heater type

As discussed earlier, space heater heats either by radiation or convection — the conventional heater that passes electricity through a heating element, causing the heating element to become hot to then pass it to the surrounding. The heat is often distributed by the help of included fan for example, the oil-filled space heaters.

The conventional heater is not actually preferable for high ceiling rooms because it would take a long while for the heat released by the heater to make the atmosphere warm, meaning you would still feel cold for some time after turning it on, unlike the infrared heaters that radiate heat through infrared rays, I.e., transfer heat directly to a solid surface just like sun heating and not the air.

The radiation heater type is the best for vaulted and high ceiling rooms because the heat released is targeted at objects directly and not the atmosphere or air in the room. So regardless of how large the room is and high the ceilings, this heater type can give heat directly to the bodies in the room although they would have to be in the range of the electric heater.

However, the conventional heater could also be used because of its ability to heat up the surrounding quickly, but you must ensure that you purchase the unit with proper rating, I.e., not less than 1500watts in the room, lesser sizes could prove ineffective.

The conventional heater with a fan ‘warms’ the room more quickly than those without fans, the ones without fans warms the room slowly because the heating element is surrounded by either oil or water which must be heated first. The risk of fire is lower with oil-filled filters than those with fans.

Installation type

An electric heater can either be mounted on the wall or left on the floor to operate. For rooms with vaulted ceilings, it is better to use the portable heater because when using a mounted heater, it would be installed mostly close to the ceiling of the room and when it starts to radiate heat from there, it takes a long while before the warmth would saturate the atmosphere and get to the people inhabiting the house.

Noise level

If you are the type of person that is very sensitive to the sound of anything, I would recommend you go for an electric heater without a fan. Most of the infrared radiation space heaters don’t make use of a fan, and they heat efficiently

Safety Feature

Safety should even be your first consideration when it comes to selecting the appropriate heater for your home. Firstly, I would strongly recommend that you opt for a heater with a thermostat for temperature control so that your heater can control itself even when you’ve forgotten that you have it on.

Also, most heaters, especially the bigger ones for the large rooms are often very heated and hot to the extent that one could feel it from the body of the unit. Therefore, it is better to go for the cool to the touch heaters that is safe for the kids and pet when touched.
