What Does “Large Room” Mean?

When we talk about “large room”, we mean 14x20ft and up. For smaller rooms, a regular 1500 watts will do.

Electric heaters can be used in any room of your home as long as it has the required electricity receptacle. In other words, you may use them in large or small rooms as long as they have their own dedicated 15 Amp circuit.

Since there are different types of electric heaters, we can’t give you a definite number of BTUs to use in your room. BTU is the unit that determines how much heat a unit will produce and the amount of electricity it will consume.

So… What is the best electric heater for a large room? In this case, your best option is Space Heater with an Adjustable Thermostat.

First of all, it is the most energy-efficient because your room will be heated at a comfortable level and not everywhere in the room.

The second reason is that you can choose the right temperature for your needs. It is much more pleasant than keeping it toasty warm all day long with one heater.

How Much Space Does a Large Room Heater Heat?

A large room heater heats up to 1000 square feet with the right BTU. The one we’ve reviewed here is capable of heating up to 1200 square feet and it uses only 1500 watts, which is equivalent to 1 kW per hour.

It’s a bit more than an average space heater consumes but still very energy efficient!

I have in mind that this heater will be used in the living room, where our TV is located. It’s just perfect to provide us with warm air when watching movies or when listening to music!

Is It Safe for My Kids?

Yes! This electric stove fireplace has safety features that are designed for the whole family to use safely.

The overheat protection feature gives you peace of mind because your children will never touch it while it is running and get burned.

It also has a timer that helps you to set it before leaving your home so the temperature will reach the desired level by the time you come back home.

That means, no one can turn it off even if they want to make mischief. Plus, there is an easy-to-use remote control.

What is the Best Place for this Electric Space Heater?

You can place it in any room of your house so long as you have a 15 Amp circuit for it. How do I know if I have one or not? If there is a switch next to the wall outlet, then you are good to go.

The switch must be turned off if there are no appliances plugged in or turned on if you plug something into the outlet.

What Should I Know About “Efficiency Rating”?

To determine how efficient a unit will be, look at the Energy Efficiency Ratio (EER). This number is calculated by the heating capacity (BTU) divided by the power input (watts).

The higher the EER, the more efficient it is. Our TOP-5 Electric Space Heaters all have high ratings and are Energy Star certified.

Most Common Uses for a Large Room Space Heater

To provide a comfortable temperature in a small space such as an office, bedroom, or bathroom.

An energy-efficient electric heater is perfect for the bedroom because it takes less time to heat up and keeps you warm all night long without costing too much to run.

In larger rooms that have even temperatures, like dining rooms and living rooms. If you have one heater for several rooms, you can set the temperature to where it makes sense.

Large Room Space Heater Features to Consider

The first thing that you should consider is the size of the room. Then decide on the BTU and maximum wattage for your chosen heater, i.e., — how much electricity does it consume? As we said before, if there is no switch next to the wall outlet or you don’t use any appliances, turn it off or unplug it.

If you want to use a heater in the bathroom, be very careful because it’s easy to get shocked. The best way not to touch it is to use an extension cord and place it far from the tub or shower where you will be standing while bathing.

Space Heater Types

There are two types of space heaters:

Convection heaters

Convection heaters are more energy-efficient than radiant heaters which only warm up objects and people in their direct path. You can use them to keep warm while you’re reading, watching TV, or working on your laptop computer.

Radiant electric heater

Radiant electric heater uses infrared light radiation to produce warmth for you to feel it. It is typically used as a secondary heating source because it heats people and not the air inside the room.

The radiant function emits infrared light from the coils which warm up anything that comes into its path. However, these types of heaters are typically much more expensive than convection ones and usually require professional installation.

How to Use a Space Heater Safely?

You should always place your heater at least three feet away from anything that could catch fire, such as furniture, clothing, bedding, or rugs. Also, do not place it on top of carpeting or near wallpaper or curtains which can easily get ignited with this type of appliance around.

Electric vs Gas – Pros and Cons

An electric space heater is more efficient than a gas one. It doesn’t require any venting or installation, unlike gas heaters. You can simply plug it in and enjoy the warmth of your room.

Gas heaters are noisier, therefore you may opt for an electric one. Electric units are also less expensive to operate which makes them more affordable to buy, maintain and use compared to gas ones that require safety inspections at least once a year by qualified technicians.
