Factors To Consider Before Choosing A Low Wattage Electricity

1.Efficient Heat Distribution

Generally, electric heaters transfer heat either by convection or by radiation.

Either type has varying application in different scenarios.

These are our recommendations for the best low wattage space heaters

Infrared heaters only provide heating for objects directly in front of them are more applicable for zone heating rather than whole room heating.

For full room heating, convection heaters with oscillation systems are recommended.

However, the plain truth is, you are unlikely to get full-room heating from low wattage heaters.

The best you can get in most cases is sufficient warmth for limited personal spaces.


It is not enough to buy a low wattage heater; you should ensure that the heater you purchase has as many mechanisms that help you to conserve energy as much as possible.

These include timers, thermostats, and remote controls and so on. While it is not compulsory that the heater you purchase has all of these features it should have as many of them as possible.

Also, having intuitive controls is a great advantage too.

You need a heater that is easy to use and understand. Having indicator lights and remote control system are simple things that can aid this.

Here are some other important control features.


A timer makes it possible to set up your heater to be turned on or off at specific times of the day, thus preventing unnecessary use and conserving energy.


this is another important control feature that helps you to control how much power your heater consumes.

An easy to use thermostat allows you to set an optimum temperature at which your heater automatically shuts off.

Programming Capabilities:

You can also get yourself a programmable heater. This way you can set specific temperatures for the heater to turn on an off at specific times of the day.

For example, you can set your heater to a higher temperature in the colder hours of morning compared.

Also, there are some latest heaters that allow you to control the temperature and other features during specific periods of the day thus allowing you to maximize energy consumption.

3.Overheating Kill Switch

Although space heaters are designed to warm up your room, they should do so without the heater itself becoming too hot.

An overheating kill switch automatically shuts off power to your heater when the heater becomes too hot preventing the heater from starting a fire or damaging your electric circuit.

4. Portability

While this isn’t a rule per se, most low wattage heaters are portable. Being small –sized makes it easy to move your heater from one room to the other which is one of the advantages of using a space heater.

Additionally, being portable is an advantage when you don’t have enough room to spare in your home.

Fortunately, there are a good number of low-wattage heaters that are so small they can be placed on bed-side tables conveniently.

5. Noise

One of the most common complaints users have about space heaters is noise.

As much as possible it is important that you find a heater that is relatively quiet or emits so little noise that is low enough for you to tolerate.

How to Use Your Low Wattage Space Heater Efficiently

A low wattage heater is an effective way to reduce electricity consumption and keep your power bills low.

However, there are simple tips you can follow that will help you manage your power consumption efficiently. Here are some simple tips that might help.

Use A Timer

Using a heater that has a timer makes it possible to effectively reduce power consumption.

You can set your timer to turn off the heater after some hours of use when the room is sufficiently warmed up or if you will not be in the house.


You can gradually adjust the thermostat on your heater until the optimum temperature is attained.

This way, your heater will automatically shut off at that temperature allowing you to effectively reduce run-time while maintaining a warm temperature that suits you best.

Programming And Timing

Using a programmable heater is another effective way to keep power consumption at the lowest.

The latest in smart home technology allows you to control your heater by simply using voice control or doing so remotely using your mobile device.

You can also program your heater to deliver different temperatures for specific periods of the day.


Insulating your room is another effective way to reduce how much time you have to leave your heater on and consequently reduce your heat consumption.

You can insulate your walls, roof, and windows in order to keep the heat from your heater within the house.

In addition to improving the insulation in your home, you can also reduce your dependence on heaters by  simply wearing warm clothing.

This way your heater doesn’t have to be turned all the way up at all times.

Zone Heating

Low wattage heaters might not be effective for heating up your whole house, but they definitely work for zone heating.

You don’t have to make use of your central heating system once you get yourself a low wattage heater.

They can be used in multiple rooms in your house and provide a cost-effective alternative to central heating. 

Safety Checklist for Your Low Wattage Space Heater

As with all electricity powered household devices, it is important that you keep safety in mind when you are buying a low wattage space heater. Click here to read the best heaters for tents.

Here are some important safety parameters to keep in mind about buying and using electric space heaters.

  • Only Buy Heaters That Have Overheat Protection

Low wattage heaters can still get pretty hot and this can cause damage to the heater and also exposes you to a fire hazard. Which is why buying a heater with overheat protection which shuts off electricity when the heater gets too hot is important.

  • Ensure That The Heater You Are Purchasing Has A Thermostat

As you can see from our list of best low-wattage heaters, not a lot of them comes with a thermostat. In fact, finding one with a thermostat control is quite rare.

However, if you can manage it, finding a heater with thermostat will be a big plus as it gives you greater control over your heater allowing you to determine how hot it gets.

This is not only good for safety but also helps to minimize electricity cost as well.

  • Always Follow Safety Instructions Given By The Manufacturer

Space heaters and other household appliances come with safety instruction on correct usage and operation. Although most people ignore these rules, it can be quite dangerous if you do.

For example, some heaters should not be used in a damp environment. This means using such heaters in somewhere like your bathroom can be quite dangerous and should be avoided.

Different heaters also have varying voltage requirements and different rules for correct maintenance.

Low-wattage heaters can get really hot too and can pose a fire hazard if placed too close to flammable items.

This is why you should keep flammable items like books, curtains and so on away from the heater on all sides.

  • Ensure That Your Heater Is Placed On A Stable Surface With Minimal Risk Of Tipping Over

Although most heaters have tip-over shut off protection which will automatically switch off the heater If it is tipped over you should still ensure that your heater is placed on a stable surface to prevent it from tipping over.

Asides the fact that falling from a high platform like table top can cause your heater to get damaged, a hot heater can still burn flammable items it falls on even if it has been shut off already.

  • Avoid Plugging Heaters Into An Extension Cord

The right way to plug heavy duty electric appliances like heaters is to connect them directly to a wall socket.

Using an extension cord can be dangerous even for a low-wattage heater as it can cause damage to your electrical system due to overloading or even start a fire.

If for any reason you will be using an extension port, ensure that it is well shielded.

  • Ensure That The Heater Is Turned Off When It Is Not In Use

Apart from the fact that leaving your electric heater on when you don’t need it will waste power, it is also not a wise decision as far as safety is concerned.

If you will be leaving your room for a while, unplugging the heater is a great idea. A heater with a timer can further assist with this.

  • Keep Kids And Pets Away

As mentioned, some low wattage heaters can still get really hot during normal operation.

This is why you should try to keep it away from where pets and small kids can make contact with the heater which can cause burns.

Frequently Asked Question

How Much Electricity Does My Space Heater Consume?

Knowing how much electricity your space heater consumes is important for determining how much you have to pay for using it.

However, calculating this depends on some parameters the most important being the wattage of the heater.

Typically, your heater should have the wattage printed on it somewhere or included in the user manual. The wattage is a measure of how much electricity is required to power it.

To calculate how much your electricity your heater consumes and how much it costs, you need to first divide the wattage value by 1000 to convert it to kilowatt since your electricity bill is measured in Kilowatt hours.

This means if you have a heater with a power rating of 700, by dividing it by 1000, the power rating will become 0.7 kilowatts.

The next step will be to calculate how much electricity your heater consumes based on how long you make use of it per day.

So if you leave the heater on for 7 hours per day, then you need to multiply 0.7 kilowatts by 7 which is the number of hours the heater stays on.

This value can then be multiplied by your utility rate which varies from one area to the other in order to determine how much using your heater is costing you.

You can also calculate how much this accumulates to per month, per week and so on.

Is A Radiator Heater Better Than A Convection Heater?

The two most common methods of transmitting heat in space heaters is either by convection or by radiation.

One of the most commonly asked questions by users is whether one of these types of heaters is more cost effective to operate compared to the other.

However, there is no direct answer to his question as efficiency depends to a large extent on how you use your heater rather than on the heater itself.

Usually, radiator heaters have a power rating of about 1 to 2 Kilowatts hour. Generally, we would say that the efficiency of your heater depends on the heater itself (i.e. the wattage), how fast it is able to do its job and for how long it stays on.

Now based on the first two criteria alone, an infrared heater might be perceived as better.

For example, an infrared heater with wattage of 1.0 kilowatts will heat up a lot faster than a convection heater of the same wattage.

This is because it supplies direct heat compared to the convection heater that gradually warms up the air.

However, efficiency is also determined based on how long you use the heater.

In this case, a convection heater is able to retain heat for longer and keep the room warm after switching it off.

For a radiation heater, on the other hand, the heat is lost the moment you switch it off. This means it has to stay on for a longer period of time which will further push electricity costs up.

Does Less Wattage Always Mean I Will Spend Less?

One of the reasons many people opt for a low wattage heater is to reduce electricity costs.

But does less wattage really mean you will spend less? In most cases this is true.

Since wattage means less power consumption it means you indeed end up spending less on electricity compared to if you are using a heater with very high wattage.

However, Wattage isn’t the only factor that determines how much your heater consumes electricity.

Other important factors that contribute to electricity cost is the efficiency of the heater itself, how fast it heats up as well as how long you leave it on for each time you use it.

Thus even if you are using a low wattage heater, how you use it is one of the most important factors that determines how efficient it is.

Does A Small Size Mean I Will Spend Less On Electricity Bills?

Most low wattage heaters are portable. However, this isn’t to say that all small-sized heaters are low wattage heaters.

There are heaters with power ratings of more than 1000 watts that are still portable.

Generally, heaters are rated by how much heat they are able to produce and not by the size of the heater itself.

Thus it is important that you check the wattage of the heater you are buying rather than assume that it is low wattage since it is small-sized.

Which Type Of Electric Heater Is The Best?

There are various types of space heaters you can buy all of them with different mechanisms of operation.

Deciding which of these heaters is best for you depends mainly on why you are purchasing the heater.

For example, if you want a heater to heat a large room, then a ceramic radiator with a fan that heats the whole room and distributes the heat evenly throughout the room is your best bet.

Radiant heaters provide direct localized heat, which makes them suitable in small closed spaces and not whole room heating.

Your choice depends mainly on your needs, and the best low is one that serves your need best.

What Is Watt Density?

This is one of the most common terms you might encounter in your search for low-wattage heaters.

The watt density is a lot different from the wattage of a heater.

The watt density is a measure of the heat flux which a heater emits per square inch of the surface area of its heating element.

It is measured in watts per square inch and is calculated using the formula below.

Watt Density = wattage of the element/ 3.14 x element diameter (inches) x heated length (inches)

The watt density is useful if you want to compare different heating elements and also helps in determining the life of a component.


Low wattage heaters provide a safe and economical means of warming up yourself at home, school, or work.

Depending on your habits, small wattage heaters can help you safely on electricity costs by supplying supplementary or additional heating to your central heating.

You can choose from our list of recommended options above.

Our buyer’s guide will also help you in making the right while giving you tips on how to make the best use of these heaters safely and keep electricity costs low.
