Best Space Heater For Large Room Reviews: Top 10 (Updated 2023)
Yes, there are other best space heater reviews out there but you are unlikely to find one as comprehensive as this. We want to make sure that you have all the important information available so that you can make the right purchase decision. You can see an overview of our top 10 space heaters for large rooms below:
What is a Space Heater?
A space heater is a convenient product designed to heat a specific space and quickly raise the temperature in that space. They perform best when used to heat a space that is closed. Space heaters are available in different styles and sizes and some of them can use combustion fuel but most use electrical power.
Some space heaters use radiant heat which is usually the most cost-effective method for heating. There are other types of space heaters which we will explain below. So if you do not have central heating (or don’t want to use it) then space heaters can do a great job keeping your rooms warm. They heat up really quickly so you will feel the benefit immediately.
How does Space Heater work?
There are two main types of space heaters which are “convective” and “radiative”. We will take a look at how both of these types of space heaters work:
Convective Space Heaters
Convective space heaters use wire elements to provide heat. A wire element is not effective at transferring heat to the air so most space heaters have a fan to assist in the flow of warm air.
The wire element in the space heater will become hot when connected to an electrical outlet. A fan will then transfer the heat generated by the element to the surrounding area or space. Electrical wire element space heaters will warm up a lot faster than an oil-filled heater for example.
It takes a lot more electricity to make an oil-filled space heater warm than it does a fan and element heater. These days the manufacturers of fans and element heaters are making them smaller all of the time so it is a lot easier to use them where space is restricted.
Radiative Space Heater
The most common form of radiative space heater uses infrared energy to create heat. A space heater of this type will emit infrared radiation to objects that are directly in its line of vision. If you only want a specific part of your room heated then this can be an efficient way to do it.
Radiative heaters are a lot more efficient than convection heaters. This means that the running costs for this type of space heater tend to be lower. The biggest problem with radiative heaters is that if you are outside of the field of vision there will be no heat benefit for you.
Is a Space Heater good?
There are a number of benefits to using a space heater. One of the most important benefits is that they can save you money. Rather than switching on your central heating system for the whole house, you can heat single rooms with space heaters. So if you tend to use one room often it can save you a lot of money just using a space heater to make it warm.
It will cost you a lot more money to heat a room to the same temperature that a space heater can if you switch on your central heating. You could actually have your central heating on to take the chill out of your rooms and then use a space heater to make the room you are in very cozy.
Usually, space heaters are pretty inexpensive to purchase. The technology used in space heaters is fairly basic and there are no complicated mechanics used to generate heat. Usually, a space heater will be energy efficient and not consume a great deal of electricity. This is particularly true with radiant-style heaters.
Most space heaters have a good design and are simple to use. All you need to do is plug them into an electrical outlet and then set the temperature to what you require. It doesn’t get any easier than that.
Some of the more sophisticated space heaters have sensors that will stop heating once a room reaches the required temperature. You can even get space heaters that have timers so that you can control when the heating starts and finishes.
Modern space heaters are usually very reliable and will rarely break down. If they do go wrong then they are usually easy to fix. If all else fails you can replace a broken space heater with a new one as they are fairly cheap to purchase.
Usually, it is easy to transfer a space heater from one room to another. Most of them are fairly lightweight so it is just a matter of unplugging it from their current location and then moving it to the next room. Obviously, you do not want to be carrying a space heater around if you have just used it and it is very hot.
There are no major installation requirements for a space heater. Unlike a central heating system which requires a skilled engineer to install it, anyone can move a space heater into the desired location and plug it into an electrical outlet.
Small space heaters can generate a lot of heat and this means that you do not usually need a lot of space to accommodate them. When you are not using your space heater you can store it away easily too.
How to use Space Heaters?
We recommend that you use a space heater if you need to provide heat to a single room or a couple of rooms. You can also use a space heater to provide temporary heat in a room that you do not use that often such as a garage or other work area.
There may be someone in your family that feels the cold more than others and a space heater can be a lot more efficient than cranking up the central heating. It will cost a lot more to have the central heating on full blast and only one person will benefit while the others are sweating.
When you use a space heater to heat up a commonly used room in your house you can either turn off the central heating altogether or have it on really low. Make sure that you keep any doors to the room you are heating with the space heater closed as much as possible so that heat doesn’t escape.
It is really important that you choose a space heater that has the capacity to heat the room. Heating larger rooms will require large space heaters. It is common sense really. If you use a space heater that is not up to the job of heating the entire room then you are going to be dissatisfied with this.
You need to think about the best position in the room for the space heater so that the heat will reach all areas of it. Be sure to position your space heater at least a foot away from a wall. For safety reasons do not position your space heater near curtains or other flammable materials.
If you have pets or young children in your home then always think about their safety. Keep space heaters out of reach of kids and pets. We recommend that you have a three-foot buffer zone around your space heater so that you can prevent burns or other injuries.
Types of Space Heaters Available in the Market
We mentioned before the two main types of space heaters which are convection and radiative. There is actually a third type which is a combination space heater that uses both technologies. Let’s take a more detailed look at each type:
The aim of a convection space heater is to heat up the air in the room rather than the people and objects in it. Convection space heaters can either use an electrical element or be filled with oil or water which heats up. When the space heater warms up the heat will rise to the ceiling. Cooler air then falls to the floor and warm air circulated.
Some convection space heaters have fans to assist in the circulation of the warm air. This is fine but they can get a bit noisy. An electrical element convection heater will warm up faster but the oil or water-filled types tend to be more efficient.
With a radiant space heater, it is the people and objects in a room that heat up rather than the air. If you are sitting within the line of sight of a radiant space heater then you will certainly feel the heat. Radiant heaters generate heat a lot faster than convection heaters do.
The trick with radiant space heaters is to find those that have a broad range of vision so that you cover most of the room. Radiant space heaters usually cost less to run than convection space heaters. They can be a danger to people and animals so you need to keep your distance from a radiant space heater.
As the name suggests, combination space heaters use the best aspects of both convection and radiative heaters. They will usually have fans to distribute the heat around a room and are usually a good choice for larger rooms.

The Best Brands of Space Heaters for Large Rooms
In truth, no one brand emerges as a clear winner when it comes to space heaters. The DeLonghi brand has a good reputation for household appliances but the two space heaters from them that featured in our top 10 were not as good as we thought they would be. The customers didn’t think so either.
Some of the lesser-known brands such as
AirNmore is certainly worthy of consideration as their space heaters have a lot of good features. Customers liked these brands and time will tell if they will maintain their standing in the market.
How to choose the Best Space Heater for Large Rooms: Buying Guide
The first thing to consider when purchasing a space heater is the type. Convection space heaters will heat the air in a room but they have the tendency to dry out the air which can get pretty uncomfortable. Radiant heaters will heat people and objects in their line of sight and are more efficient usually saving on electricity costs.
A radiant heater with fan assistance helps to spread the heat around the room more efficiently. There are also space heaters that use mica technology and these will heat a room quickly and distribute the heat well.
The next thing to consider is the size of the room that you want to heat. Large rooms will require a heat output of 1,500 watts to make them comfortable. Some space heaters are better at heating large rooms than others. A radiant heater with fan assistance can do a very good job as can a powerful convection space heater.
A radiant heater is usually more energy-efficient than a convection heater. This is not always the case so you need to do your homework here. If you use a space heater for many hours then your electrical bill is going to go up. If the space heater is more efficient it won’t go up too much.
Safety is very important with space heaters. Some of them can get very hot and cause burns to young children and pets so check what safety features are included. A tip-over cut off and an overheating protector are definitely worth looking out for.
There are some silent space heaters but most of them will make some kind of noise. This may not be a big issue if you are using the heater in the living room but in the bedroom, it is very important. Check the noise output of any space heater you are considering.
