Buying Guide: Heater For Large Room

One of the essential appliances to have if you live in any cold part of the world or experiencing chilly winters is a heater. However, not all heaters can serve every space.

Heaters for large rooms are designed with the primary intention of supplementing a central heating source of heat like a furnace, boiler, or heat pump. They help keep your bedroom toasty in winter while saving electricity money when you do not have to turn on another source of heat.

In this buyer’s guide, you will find out the reason the best heaters for a large room will be a worthwhile investment and how to quickly choose the most suitable for you among the models reviewed here.

What is a Heater for Large Room Used For?

When you have a large room with a lot of space, you may not get efficient heating from normal heaters. If you have up to 800 to 1,000 square feet of insulated space, you should get a large room heater.

Electric large room heaters can produce up to 1500 watts, while propane heaters offer about 9,000 BTUs. This is enough to keep you warm and comfortable in cold weather.

Large room heaters can be used in living rooms, TV rooms, bedroom-bathroom suites, rooms with drafty windows or poor insulation, rooms too far from the heat of the central heating source, small apartments, condos, townhouses with open floorplans, small bungalows with open floorplans, cabins, small vacation homes, damp and chilly unfinished basements, bonus rooms that are above garages, small additions to the home, insulated workshops or garages, large RVs, and any other poorly heated space.


Features to Look Out For

You can spend the whole day shopping for the best heater for a large room if you do not know the particular features to look out for. How else will you pick out the heater that works best for your home without some key features to guide you? 

Here are some main features you should take into account before buying your large room heater:


When you get to the marketplace, you will see different types of heaters for large rooms. How can you tell the difference between each of them if you do not have prior knowledge of them?

Here are the major types of heaters for large rooms:

Ceramic space heaters

These heaters follow the convection principle. First, they heat up the air, then they disperse the heated air throughout the room. More so, ceramic space heaters can cover a more extensive area than radiant heaters. Another great feature of this type of heater is that it can function without the need for any kind of fuel.

Convective space heaters

Convective space heaters typically come with fans that blow heated air and circulate it around your room. They are affordable, user-friendly, but a little noisy.

Micathermic space heaters

Micarthermic space heaters are designed to be quieter than other types of heaters. The heating system is a combination of radiant and convection systems. They have no fans and are suitable for people suffering from asthma and/or some other allergy.

Oil space heaters

Although these heaters do not heat up quickly, when they finally do, they can warm up a considerably large area.

Radiant space heaters

These heaters do not blow air and do not circulate warmth throughout the room. Instead, radiant space heaters only transfer heat to any space, person, or object directly in front of them. They are very handy when you only want to warm a particular corner of your room. People with allergies should go for these heaters.


Focus on the brand, craftsmanship, materials, design, and overall quality of the heater you are buying. This will determine how long it will last and save you money.

In ensuring that your heater is more durable, go for the one made from stainless steel instead of the one made from BPA-free plastic.

Remote Control

A heater with remote control will allow you to control the switch as well as control the temperature from your comfy sofa. Some new models have this feature, but some models no not. 


Room heaters are not too pricey, compared to some other heating devices in the market. As a matter of fact, with a reasonable budget set aside, you can get a high-quality room heater that uses less electric power.

Ease of Use

Ease of use is one factor you should not overlook. Your heater must be simple to use. You should not need a technician to plug it into a power switch and adjust the temperature for it to start working.

Heating Area

In your quest for the best heater for a large room, you need to concentrate on heaters with enough capacity for larger areas. Some can accommodate up to 100 sq ft. Although these heaters are meant to supplement your central heating system, they should still have a large coverage area. Choose a heater with more heat circulation.


A heater’s wattage has to do with its maximum electrical power output. The higher the wattage, the more the power generated. 

Also, look closely at the number of settings on the heater. The more the number of settings, the more the temperature control. You can get an eco-mode feature, which is about 500 Watts so that you will save up on electricity bills.


The heater you end up buying should come with some safety features like overheat and tip-over protection. Your heater should be able to switch off automatically when the heater is tipped over. This makes it ideal for use in a house with children and pets. This is a way of guaranteeing overheat protection.


With a timer, you can control how long the heater will say on for. A timer is necessary when you have a schedule but no time to always turn a switch on and off.


You will save some more money if you get a heater with an efficient thermostat. The thermostat’s work is to keep your room at your desired temperature. It will help to keep the heater at a constant temperature by turning the appliances on and off as needed.


Heaters should be lightweight and very portable so you can easily move them from one place to another. Some heaters come with wheels and/or handles to ease transportation.


The best heater for large rooms can circulate heat in a large room without disturbing anyone. This is because they come with mounting capabilities that allow you to choose whether you want to mount them on the wall, ceiling, or anywhere else above the ground. It is a great idea for homes with pets or small children so they do not knock the heater over.

Safety Precautions

If you are using the best heater for large rooms as a secondary source of heat, keep it away from the primary source. Also, combustible materials should be kept at a distance of not less than 5 feet away from your heater to avoid ignition.

Most manufacturers advise against the use of extension cords due to the higher risk of fire. More so, extension cords can be trip hazards for both kids and adults.



Are Heaters Better than Central Heating Systems?

Here are some very important reasons why you should invest in the best heater for large rooms instead of using central heating systems:

Increased Efficiency

Heaters for large rooms are very effective since they produce enough heat for a whole room. Despite their relatively small construction, they provide warmth and comfort to your living space. Additionally, they are easier to set up and start using without being tech-savvy.

More Cost-Effective

These heaters are affordable and do not add too much to your heating bills. It is cheaper to run a space heater for a particular room you are using, instead of using a central heating system which will heat up even rooms that are not in use.

More Portable

You can easily move these heaters from one place to the other, including outdoors. You can take them to any space you want to heat, and even lend it to a friend.


Most ventilation systems and furnaces have a drone sound that takes some getting used to. With heaters, however, you do not have to worry about noise. They run quietly, allowing you to focus on other things while doing their job.


The design of these heaters ensures they are safe for indoor and outdoor use. Most of them come with safety features that automatically kill the power when necessary. To enhance the safety of these heaters, some brands incorporate an automated kill switch that turns off the heater and fan when the heater tilts at an angle or tips over.


Did You Know?

You can clean your heater with a brush and a slightly damp sponge. However, make sure it is first turned off, disconnected from the outlet, and its cover is removed.


Expert Tip

If you have children or pets, make sure your heater can be mounted on ceilings or walls, and have designs that are safe to touch. This will help to avoid incidents and ensure your children’s safety.
