Buyer's Guide

​With so many reliable products in the market, it is certainly difficult to make a decision right away. Still, it's possible to save some time if you know some of the important factors that you need to consider before buying your ideal product. Here are the three most important ones you need to look at.

​1. Oscillation power

​This also comes in handy because it ensures your room is heated quickly and evenly. This is important because you don't want people in one corner of the room feeling hotter than people sitting in the other corner.

Having better oscillation power also ensures that the heat is rotated evenly in the room, and the fans run at a faster speed. Moreover, in the summer months, you can switch off the heat and use the space heaters as oscillating fans only.

​2. Portability

Space Heaters Buying Guide

Like previously mentioned, portability is a huge benefit of a space heater. The biggest issue people face with the centralized heating system is the limitations of space. They can only be used for that specific room and area and cannot be transferred elsewhere.

With a space heater, that's not the case. They don't require any installation or mounting to the walls, which means you can transfer them to any room in an instant. Moreover, even if you choose a wall-mounted or baseboard heater, you will only have to unmount the heater without spending any time on drilling or removing screws.

​Any person who wants to achieve convenience and comfort will opt for a portable space heater. This makes it easy to use one space heater for multiple rooms. It is also safer to carry them around as they are usually compact and are less likely to fall. Moreover, they are more convenient to install and unmount.

​3. Safety

​If you live alone or with a family, the last thing you want is for your heater to be unsafe. Contrary to what people might think, there are many models out there that are dangerous and can cause a lot of problems.

Space heaters are relatively safer as they come with anti-tip switches that cause the heater to switch off automatically when the room gets warm. This also comes in handy if someone leaves their heat switched on for the night. This switch also ensures that the heater turns itself off if the oxygen levels in the room get too low.

Look for a space heater that comes with various safety features.

​4. Quiet and peaceful

Another major benefit of these space heaters is that they are extremely quiet. This is because they come with a fan that rotates heat silently and efficiently. The quiet and peaceful conventional currents also provide warmth without using too much power. These hence allow you to enjoy a good show or a good book while staying completely warm. You should buy a space heater that makes very little noise.

5. Ease of use

Some space heaters are better at controlling than others, but almost all of them offer some level of control to the user.

They come with options that allow you to change the heat settings as well as the fan speeds.

Moreover, they come with either manual or digital thermostats that not only allow you to switch them off easily but also help in the conservation of energy.

Look for space heaters that have a digital display or remote control, which makes them very easy to use.

Space Heaters Buying Guide

​6. Price

​Unlike other heaters, space heaters are relatively cheaper and hence easier to purchase. They also require little or no setup, which also reduces installation costs. They also save costs by reducing the heating bills for you.

Not only this, if you have a centralized heating system that you switch every now and then to warm a room, but you will also undoubtedly be wasting tons of heat and energy. This is not only uneconomical but also irresponsible, given the current energy crisis in the world. So investing in a space-saving heater is likely to reduce your electricity bills and only heat the room for as long as you wish.

This one is pretty obvious, but a lot of people ignore its importance. There is a circulating myth that only the most expensive space heaters offer efficiency. This is totally false as you can get your hands on an efficient model without spending too much.

Frequently Asked Questions

​Space heaters for larger rooms are very popular, and with so many products in the market, a person can have a hard time deciding the best one. We will be answering some of the most frequent questions to help you make a choice better.

​Q. How much electricity does your heater use?

A. The cost of electricity that is taken by any space heater is given by kilowatt per hour of the electricity used. In most instances, a space heater can consume up to 1500 kilowatts of energy every day. This is only if the heater is switched on for 24 hours.

​Q. What sized rooms can a large space heater heat?

A. All the models in the review are suitable for larger rooms, but that may also vary from model to model. Making a rough approximation, you would only require around 10 watts of heat for each square foot of the surface area of each room.

So assuming that is a 1500 watt heater, it can warm an area comprising a total of 130-180 square feet.

Q. ​What is BTU, and what does it mean in regards to a space heater?

A. BTU refers to the British thermal unit that is a non-SI traditional unit used for heat. It is also defined as the specific amount of heat that is required to raise the temperature of a pound of water by at least one Fahrenheit.

A 1500 watt heater is likely to warm a small space; however, it can produce more than 5100 BTUs of heat in an hour, which can cover large rooms as well.

​Q. Can I leave my space heater on all night?

A. No, ideally, you shouldn't leave your space heater all night. Even though rising technological advancements have made this equipment safer, it is still better to be safe than sorry. Moreover, leaving heaters on the whole night can add tremendously to your electricity bill.


​Investing in a new product can be hard, especially if you are tight on budget. But investing in the best space heater for large rooms will prove beneficial both in the short and long run. These are compact, portable, and highly efficient heating equipment that can uplift your mood in an instant. They produce heat at a faster rate so that you can enjoy a comfortable environment at all times.

But before you make this life-altering decision, make sure you understand your own needs. The market today is bombarded by all sorts of products, some are good, and some are perfect. The perfect ones have been thoroughly discussed above. However, you need to always remember that no matter how amazing a product is, if it doesn't suit your needs, you shouldn't invest in it.

So make sure you measure the square feet of your room and then choose an appropriate heater. Moreover, to get the best results, ensure that you compare the pros of each model with its cons, and then choose.

Here’s to staying warm, Folks!
