The 8 Best Electric Heaters with Thermostats

A house is not at all accommodatable when it lacks a proper heating system and therefore architects and builders along with owners pay special attention to heat vents and the whole system. Every house is equipped with a centralized heating system which keeps the temperature inside the house normal even when it is freezing outside. But there is only so much that the centralized heating system can do and it too, comes with a lot of limitations.

The biggest of its limitations is the inability to provide apt heat at different places around the house. Different places in the house have different temperature conditions. Some places are very cold and hence need a lot of heating like the garage whereas some are not that cold. So, there is a need for extra heating in some places in the house.

A space heater does just that by providing you with the extra heat that you are devoid of. Unlike a centralized heating system, a space heater comprises a single unit heater that runs either on electricity or fuel and acts as a comforter in winters.

Space heaters could be used in the bathroom, in the garage, and in the bedroom when you want some extra heat to feel your body once again. These are small to medium-sized equipment that is used in closed spaces and are comparatively cheaper than central heating systems.

Space heaters can both be fixed to the wall or could be portable. They also come with an inbuilt thermostat which is responsible for monitoring the temperature of the room and maintaining it at a normal level so that it does not get too hot or cold.

Space heaters are a very important piece of equipment that you must possess if you feel that your central heating system is not that effective enough. These heaters could also be used in your workplace to keep it warm and productive.

Selecting a good electric space heater with a thermostat for you could be a tiresome job. But before learning the art of buying the most suitable space heater with a thermostat for yourself you must be aware of the different types of space heaters.

Types of Space Heaters

Space Heater with A Thermostat

There are three main types of space heaters.

Convection Heaters

These types of heaters use the properties of air to stimulate and distribute heat around the room. The warm air comes out of the heater and rises above making the cold air settle down and get heated by the heater, the cold air becomes hot, and the cycle continues. This gradually increases the temperature of the room.

Infrared Heaters

This is the second variety of heater that does not use air to increase the room temperature but instead, uses radiation. The infrared heaters used infrared lights that bounce on the solid surfaces of the room and increase the temperature in this process. These heaters could only work properly if the room is small and there is a proximity of other items that could help in the radiation of heat. They are ineffective in big empty rooms.

Fan-Forced Heater

These heaters are especially very loud. They pump cold or normal air through a heated surface making the air warm. This is the same technique that is used in refrigerators and air conditioners.

Now that we are aware of the different types of a space heater with a thermostat, let us learn the easy way to buy a space heater that is perfect for you.

How to Buy A Space Heater with A Thermostat?

Before buying a space, heater there are a lot of questions that you need to find answers to so that you end up buying the best space heater that suits your needs exclusively. These questions are related to the type of heater you want, the heating output you want, the place you want it for, whether you want it to be portable, etc.

So, several factors decide which space heater is best for you. Make sure to check through all these factors to be certain that you have purchased the best space heater. These factors are-

Heater Type

While purchasing a space heater you need to decide which type of heater you want. It could be a radiant heater or a convection heater or a fan-forced heater. If your room is small or filled with furniture and stuff, then you should purchase a radiant heater but if not then you can purchase either a convection heater or a fan-forced heater.

Apart from the way of operating, space heaters can also be divided into four different categories based on your needs. If you want a small portable heater that you can carry around and use for your work then you should consider buying a personal space heater, as it is small, light, and effective for a single person.

A smaller space heater is the second variety slightly more extensive than the personal heaters and provides more heat. Larger space heaters are even more significant and costlier than small space heaters. Oil-filled heaters are the biggest of all space heaters and cover the most area. They are bulkier than other space heaters. So, you should be sure of what size and type of space heater you want.

Energy Efficiency

Energy efficiency is a very technical aspect of buying a space heater, and you should investigate it very carefully. It means the amount of energy being consumed by the space heater. Space heaters are infamous for skyrocketing your electricity bills, and there is no way can prevent it from increasing.

But with proper assessment and planning, you can buy a space heater, increasing your electricity bill to a minimum extent. You can do this by finding out the room area where you want to use your space heater. If the room is small, then a medium to low-powered heater would work, but if the room is and vice versa.

Heating Capacity

The heating capacity of the space heater should also be given a thought before purchasing one. Normally, 10 watts are required to heat one square foot of area. So, by this logic, a room with an area of 150 square feet would normally require a 1500-watt space heater to keep it warm.

There are a lot of different factors that determine the heating capacity of the heater, but its power rating is the biggest of them all. So, knowing the size of your room while purchasing a space heater is necessary.

Safety Features

A space heater is not a toy and this needs to be handled carefully. Some incidents involving space heaters are fatal and thus you need to be very careful while using them. The companies and manufacturers also are very concerned about the safety issues and are trying their best to make space heaters safe.

An inside key is now installed in the heater so that it turns off automatically when it is tumbled down. Some space heaters also turn off automatically after they have overheated. There is also a timer feature that helps to switch the heater off at a predetermined time in the future. This feature is also very helpful in saving electricity.

Noise levels

Space heaters that use fans produce a lot of noise. If you want a space heater for your working space, consider buying a fan-less space heater. Oil-filled space heaters are the best when it comes to quiet operation.

They are almost unnoticed when they are switched on. So, you can use oil-filled heaters if you do not want too much noise. After going through all these factors, you will narrow down your list of space heaters that you want to buy.

Here are some of the best space heaters with thermostats that you might be interested in. You can select between them using the guide mentioned above.

Let us look at the answers to some frequently asked questions.

Do Space Heaters Have Thermostats?

The thermostat is equipment to monitor and control the heat being discharged by the space heater. Both products are complementary. But a space heater does not need to come with a thermostat and there are a lot of space heaters (mostly low end) that do not have a thermostat. In case there is no built-in thermostat in your space heater, buy one separately for safety and convenience.

Can You Have A Space Heater on All Night?

Keeping a heater on while sleeping could be hazardous in many situations, but with advancements in technology safety, this problem is no more a problem. Modern space heaters can switch off automatically if they are overheated or tipped off, so you do not need to worry about switching them off yourself. The automatic thermostat also regulates the temperature by itself.

What Is the Best Kind of Space Heater?

There is no one best kind of space heater, and the best space heater for you depends on several factors. For example, a space heater that is best in performance might not be the best for you as its price may surpass your budget.


Space heaters come in a variety of shapes, sizes, power ratings, price ranges, etc and it is you who needs to decide the best by analyzing all these factors. Always form a budget and write down your expectations from the space heater you want.

Though space heaters now come with advanced technology that makes them the safest heaters it is always in your best interest to take precautions and use these devices safely. Never put a flammable item in front (3 feet away) of the heater. Also do not switch on the heater if there is no adult in the room. 

Always check the cords and pins of the heater. Also, make sure to test the tip over and overheating features of the heater in regular intervals to make sure that everything is working properly. Always try to buy a space heater with a thermostat installed in it beforehand.
