Best Space Heater for Large Rooms (Reviews + 2018 Buying Guide)

So here is the truth...

Most fall and winters months can be really harsh. If you are searching for the best space heater for large rooms to supplement the heat from your central heating system, you have come to the right place.

Could be that your house or apartment is not well insulated; I know mine was not at some point and it would get extremely cold and drafty.

I was not aware of it but..

Whenever we used the conventional heat from our central heating system, for some reason, the four of us (my wife, the boys and I) would wake up with dry or parched throats.

I knew that I had to get an indoor space heater.

One evening after work, I got on to my laptop and started searching for a space heater that would work for us.

...Kilowatts, infrared, forced air, quartz, radiative, convective, micathermic..

All these variables were just too confusing.

I just wanted something to keep my family warm.

The purpose of this article is to guide you from NOT going into the same unending spiral on the internet as I did.

It is simple really, if you are looking to supplement heat from your main source, find a space heater with good reviews, purchase it, plug it in, get warm. That's it.

Space Heater Types

Radiant Space Heaters

The easiest way to explain radiant space heaters to you is to say they transfer heat to the person or object that is directly in their path. So if you are moving around in your indoor space, you may not experience the heat from such a heater in some areas.

They do not heat the air in the room. Since they do not blow air, such heaters would work well even for those with allergies.

I should also mention these heaters are relatively quiet. Radiative heaters slowly warm your space, and keep it warm even long after they have been switched off. The most common of such heaters are the infrared space heaters

Convective Space Heaters

These heaters have fans that blow air through heating elements then circulate this warm air into your space. You can be sure these fans make some noise, so this is not a heater you would want in your child’s room as they try to sleep or just about anyone who doesn't do well with noise. 

They are ideal if you are looking to raise temperatures fast.

Ceramic heaters fall in this category. These heaters are popular, so you will find variety and budget choices.

Micathermic Space Heaters

If you suffer from asthma or any allergies, this type of heater would work for you. They are fanless, quieter than many other space heaters and do not circulate any dust.

These heaters are a combination of radiative and convection heating systems. Most of these heaters have a wider base so they can be placed on the floor or even hang on a wall.

Best Space Heater for Large Rooms: Buyers Guide

Here are some factors to consider...

Size

You will notice that most heater manufacturers recommend 10 watts of heating power for a square foot of living space. So a 1500 watt heater is ideal for 150 square feet of room.
