Best Space Heaters Buying Guide

It’s always advisable to get acquainted with the information and facts that will be useful to know when looking into purchasing a heater which you can rely on. When selecting the most suitable space heater you’ll want to consider the following before jumping in:

Different Types Of Space Heaters

  • Convection Heaters 

Convection heaters work by utilizing the natural movement of airflow and the buoyancy changes of air when it becomes heated. We have all heard the fact that warm air rises and convection heaters warm the air that reaches the heating element.

When the warm air moves away, cooler air shifts towards the heater which in turn is warmed until all of the air in the room is a uniform temperature.

Convection based space heaters can either generate heat by using oil based resistors or ceramic heating elements, but both still rely on gradually heating the air in the room rather than heating a specific space like in the case of radiant heaters as explained further below.

Fan assistance can also be used, and of course, oscillating space heaterscan be found which are designed to rotate. The fan assisted heater draws in the cool air, speeding up the process of warming the room.

The only downside to having a fan is it may produce unwanted noise which to some may not be an issue if you wish to use the heater for your garage alongside power tools.

  • Radiant Vs Infrared Heaters

As you can tell by the name, radiant heaters project invisible infrared energy waves which are absorbed by other objects and so heating them in the process. This type of space heater is much better used for personal warmth and not particularly useful for heating the whole room.

Given that they are not as effective for a large room, they are however effective at warming the area it is directed at very quickly and so radiant heaters are great for short term use.

Infrared heaters use either gas or an electric power supply and are a great money saver for those who only need temporary use.

You will also prefer to use a radiant heater in a room which is draughty or has poor insulation, as a convection heater may not prove enough to keep a steady warm air supply, and so at least with a radiant heater, you can have direct the warmth towards yourself as and when you need it.

A final note on radiant heaters it hat they are suitable for outdoor use, so some would be perfect to place on the patio when having a garden party, used as a heater for a smoking shelter and would be the best choice when it comes to a space heater for camping or for fishing.

  • Baseboard Heaters

A sleek and compact solution for more long-term usage is the baseboard heater. They are usually installed close to the floor (hence the name) and you are not able to move them from room to room as easily but they are quite compact and do not pose much an issue when it comes to space conservation in the home.

They all come with an inbuilt thermostat and can be tuned independently to fit the room that the heater is installed in.

Suitable for anything up to a large room, they are a great option for those who wish to selectively control the temperature in each room to fine tune the power usage. Baseboard heaters also help to reduce heat loss through window draught after using the central heating.

Pros And Cons Of Different Types Of Space Heaters

Advantages Of Convection Heaters

  • Most convection heaters have a thermostat feature which allows you to control the temperature of each individual room you put them in.
  • The room is warmed gradually and evenly, which adds a unique comfort to the room.
  • Panel convection heaters can be placed seamlessly onto the wall or into wall and floor panels making them ultra-portable room heaters for long-term use.

Disadvantages Of Convection Heaters

  • Fan assistance can be noisy which to some may not be a desirable side effect of having a fan.
  • The lack of air filter can mean that dust particles are blown around which would disturb those with dust allergies.

Advantages Of Radiant Heaters

  • Short-term use means you will conserve more energy.
  • Provides warmth to a localized area very quickly.
  • Suitable for outdoor use.

Disadvantages Of Radiant Heaters

  • Short range heat projection.
  • Not a great heater for large rooms.
  • Not a great heater for long-term use.

Advantages Of Baseboard Heaters

  • Can be compact in design and installed on the wall, conserving space.
  • Great for heating large rooms for long periods of time.
  • Great for temporary use or when you have no need for heating all year round.

Disadvantages Of Baseboard Heaters

  • Zero portability, the heater must be installed.
  • Common to have fan assistance and so may not be silent.
An advantage to all types of space heaters is that they’re not messy like a wood burning fireplace can be. They require little maintenance nor do they require tools such as fireplace tongs or a soot vacuum.

Factors To Consider When Buying A Space Heater

1. Price 

The price of the heater, without a doubt, is going to be an important factor in your decision making.

Therefore, it’s important to consider the many different features it is equipped with, as you will find a lot of different affordable space heaters on the market which have a different variety of features and so just make sure you compare the specs between the various models to ensure you aren’t just paying for something you could get for a much better price.

You should keep in mind that they do consume fuels in the form of electricity or gas and therefore these costs should be factored into your decision making, although, it’s also important to bear in mind that a good space heater will help you save on heating bills during times you might have been tempted to unnecessarily use your central heating system.

2. Specifications

You can find out more about the different types of space heaters below in the section about types of space heaters but when it comes to exact specifications, no matter which type of heater you own, it’s the actual components that determine the quality and lifespan of your heater.

Therefore, it’s worth knowing which parts of a space heater are most important. A good example of an essential component of your heater is the heating element itself.

A PTC ceramic heating element in most cases would make a more energy efficient space heater than a standard ceramic element as it automates its own temperature and the rubber acts as an insulator maintaining more heat whilst reducing energy consumption.

3. Portability

Portability is a major feature that you may want to consider depending on your specific needs and living arrangements.

You may find that you only wish to warm the one bedroom but have very little or no space for a large heater. Larger heaters such as the DeLongi Radiant Heater overcomes the loss of portability due to size by adding snap-on wheels and a convenient carry handle whilst other space heaters are no burden at all due to their compact designs and having little weight.

The size and encumbrance of the heater are important when it comes to the precious space we have in our homes and so be sure to make sure you have enough space for the heater you are going to purchase, especially if you are interested in large convection or radiant heaters.

4. Energy Efficient Space Heaters   

When we look at the energy efficiency of a space heater, we are thinking about how much energy we are using and ultimately paying for in order to heat up a room.

Energy efficiency is not just a financial concern but an environmental concern and that is why features like oscillation and self-regulating temperature controls are very beneficial to those who want an eco-friendly space heater as they function to heat up large areas at a quicker rate.

It comes down to choosing the right size heater to suit your needs. If you find that you are mostly at your desk at home or at work, you may find you’ll only need a small heater like the Honeywell Uberheat which provides plenty of personal warmth and also slightly warms the room you are in.

Electric Space Heater Safety Guidelines

When discussing heating a room using any type of appliance, safety is always at the forefront of one’s mind. That is why there are space heaters which have a safety shut off feature to prevent the appliance from overheating.

As well as for events when it has been knocked over and averting a disaster, therefore, they are always a smart option to consider. Please note that it is important to refer to the specific user manuals and warranties provided by your space heater’s manufacturer.

  • You should always consider where you position your heater to reduce the risk of fire. A flat surface so that the heater does not fall over, an area where the heater will not be exposed to water and somewhere which is ‘low traffic’ to reduce the chance of somebody being tripped over by the power cable.
  • Make sure the location you put your heater is dry and free from the risk of it being exposed to water as this would pose a safety hazard to yourself, other people and can cause damage to the heater too. Also, ensure panel heaters which are installed into wall tiles are installed correctly and are watertight.
  • Heaters can get hot to touch, especially convection heaters, and so be very careful when you are considering purchasing, as you may want to opt for a space heater, which is better for those with pets and children like ones which use radiant
  • Be aware that you should not use a heater at all if you find any damage to its power cable. Switch off the appliance by the power source immediately if you do notice any compromise to the power cable and contact the store or the manufacturer.
  • Finally, it is important to remember to not leave a powered space heater unattended. If by any chance safety procedures do fail, the hazards are very serious if the heater is left on and by itself. The number one rule is to remember to always switch your heater off before leaving the heater unattended.

Will A Space Heater Save Money?

There’s no doubt that a space heater has great potential in saving you money if you were to be conscious of precisely when and how much you use the heater as well as the size of the room you are intending to heat and how well insulated it is.

Using a space heater to supplement the heat you have generated from your central heating use will no doubt be a sensible way to save money instead of switching the central heating back on again if you don’t reach sufficient warmth in the room. This method of use is suitable for those with large rooms or who still wish to heat the whole house.

If you are somebody who has no heating at all in their home, then it would be a decision for you to make on how many rooms you want to heat.

If you live in a small apartment or only wish to heat small rooms, it would then seem like a great idea to have a convection panel heater but if you have many rooms and/or large rooms that are constantly in use then you may decide that central heating may offer better value for money.

Keeping things close and personal with a radiant heater saves time and energy on heating a room which has poor insulation. In this situation, the air which a convection space heater has already heated will escape the room and prove inefficient and costly.

Final Words


Hopefully, the overall message of this article is that your ideal space heater depends entirely on your own heating needs.

There is a high variety of different models available to buy online, some of which are highly affordable and some of which have a good range of customizable settings and smart safety features.

You must consider the amount you wish to use your heater, where you are planning to use it and whether or not you want to heat a room of a particular size or to have a heater for your own personal use.

However, when used in accordance with your central heating, or used alone to heat a small room, a good energy efficient space heater is going to serve you well in the long run.
