What is a Space Heater?
A space heater is a convenient product designed to heat a specific area and quickly raise its temperature. They perform best when used to heat a closed space. 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 heating method. There are other types of space heaters that we will explain below. So if you don’t have central heating (or don’t want to use it), space heaters can do a great job of keeping your rooms warm. They heat up quickly, so you will feel the benefit immediately.
How does a 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 help circulate 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. Electrical wire element space heaters will warm up much faster than oil-filled heaters, for example.
It takes a lot more electricity to heat an oil-filled space heater than it does a fan-and-element heater. These days, the manufacturers of fans and element heaters are making them smaller all the time, so it is a lot easier to use them where space is restricted.
Radiative Space Heater
The most common form of radiant space heater uses infrared energy to create heat. A space heater of this type will emit infrared radiation toward objects directly in its line of sight. 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 radiant heaters is that if you are outside the field of view, you will not receive any heat benefit.
Is a Space Heater good?
There are some 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 to just use a space heater to warm it up.
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 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, with no complex mechanics required to generate heat. Usually, a space heater is energy-efficient and does not consume much 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 set the temperature to your desired setting. 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 with timers so you can control when the heating starts and stops.
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 inexpensive.
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 them from their current location and then moving them to the next room. 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, anyone can move a space heater to the desired location and plug it into an electrical outlet.
Small space heaters can generate a lot of heat, so you usually do not need much space to accommodate them. When you are not using your space heater, you can easily store it away, too.
How to use Space Heaters?
We recommend using a space heater if you need to heat a single room or a couple of rooms. You can also use a space heater to provide temporary heat in a room you don’t use often, such as a garage or other work area.
There may be someone in your family who 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 keep the central heating on full blast, and only one person will benefit while the others sweat.
When you use a space heater to heat a commonly used room in your house, you can either turn off the central heating altogether or have it on 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.
You must choose a space heater that can heat the room. Heating larger rooms will require large space heaters. It is common sense. If you use a space heater that isn’t up to the job of heating the entire room, you’ll be dissatisfied with it.
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, always prioritize their safety. Keep space heaters out of reach of kids and pets. We recommend a 3-foot buffer zone around your space heater to prevent burns or other injuries.
Types of Space Heaters Available in the Market
We mentioned before the two main types of space heaters: convection and radiant. There is a third type: a combination space heater that uses both technologies. Let’s take a more detailed look at each type:
Convection
A convection space heater aims to heat 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 circulates.
Some convection space heaters have fans to help circulate warm air. This is fine, but they can get a bit noisy. An electrical convection heater will warm up faster, but oil- or water-filled types tend to be more efficient.
Radiant
With a radiant space heater, it is the people and objects in a room that heat rather than the air. If you are within line of sight of a radiant space heater, you will certainly feel the heat. Radiant heaters heat up much faster than convection heaters do.
The trick with radiant space heaters is to find those with a wide field of view so you can cover most of the room. Radiant space heaters usually cost less to run than convection space heaters. They can pose a danger to people and animals, so keep your distance from a radiant space heater.
Combination
As the name suggests, combination space heaters use the best aspects of both convection and radiant heaters. They will usually have fans to distribute heat throughout a room and are a good choice for larger rooms.

The Best Brands of Space Heaters for Large Rooms
In truth, no single brand emerges as a clear winner among 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 expected. The customers didn’t think so either.
Some of the lesser-known brands, such as
Unique Heat,
EdenPURE and
AirNmore is certainly worth considering, as their space heaters offer many 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 heat the air in a room, but they tend to dry it out, 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 a fan helps spread the heat more evenly throughout the room. There are also space heaters that use mica technology, which heat a room quickly and distribute 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, your electrical bill will 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 worth considering.
Some silent space heaters exist, but most make some kind of noise. This may not be a big issue if you use 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.
