De’Longhi micathermic wall-mounted portable panel heater
Let’s take a look at another type of space heaters for large rooms: micathermic.
Micathermic heaters are unique in a way that they produce both convection and radiant heat. This combination allows them to not only heat the room faster but also stand out as the most efficient space heaters for large rooms.
Micathermic space heaters also tend to be a lot thinner, including this one. De’Longhi Mica Panel is only 5 inches wide so it won’t add unnecessary bulk to your room. And, with an included kit, you can mount it on a wall to save floor space.
But let’s look at it as a potential heater for large rooms. As mentioned, it produces two types of heat. But its most important element is mica sheets which are great conductors of heat. This allows a heater like this to warm up a large room faster and more efficiently than infrared heaters.

Types of electric space heaters for large rooms
We’ll be honest, there are a lot of types of electric space heaters out there. But knowing how each type operates and what are their main benefits will help you decide on the one that works best for you and the sq. ft. of your room.
So let’s look at what are the types of space heaters for large rooms:
If you’ve ever dealt with an oven, you’ve dealt with convection. And convection heaters deal on a similar principle.
It is capable of warming up the room thanks to two factors – a heating element and a fan blower. The former is usually an electric coil, heated oil, or electric wire. Once it has heated up, these space heaters use fans to circulate air around it and into the room.
Due to them relying on the warm air, convection heaters are great for warming up the whole room, from floor to ceiling. They also do a fast job of it, since the warmth gets pushed out at a high rate as soon as the coil has heated up.
However, a cold draft can interfere with the machine’s efficiency at heating up the room. They can also be quite noisy and not the best choice for a home office or bedroom. Due to its heating capabilities relying on free airflow, it can struggle with distributing heat in cluttered rooms or if something is blocking the fan.
Radiant (infrared) heaters
Infrared heaters can be described in one sentence: they heat up objects, not air. If you had to compare their operation to anything, it would be sunlight. They provide near-instant heat and work best as spot heaters. However, modern radiant heaters come in combination with high-efficiency blowers as well as an oscillating component. This makes them great heaters for large rooms.
Infrared heaters are quiet and provide you with direct heat. If you have high ceilings, this option may be more budget-friendly since it will warm you up with struggling to heat up empty space above. Some are easily capable of warming up to 1000 square feet.
Additionally, if your infrared heater doesn’t have a fan, it doesn’t circulate dust and pollutants around the room. Plus, infrared heaters are famous for keeping the air in the room nice and humid.
However, the downside of infrared heaters is that once they are turned off they don’t emit residual heat. And as mentioned before, they don’t warm the air but the objects. So make sure nothing is standing in its way.
Ceramic heaters are considered to be the most energy-efficient heaters for large rooms. They operate by heating a ceramic element inside. This ceramic element is capable of regulating its own temperature, easily reducing the produced heat if the desired temperature has been reached. It wastes less energy heating the ceramic plate as well as the room in general.
So yes, if you are looking for a large room space heater that is budget-friendly in terms of future electricity bills, a ceramic one is a great option. They consume the least amount of energy among other types of indoor electric heaters.
However, since this is supposed to be a heater for a large room space it will need a powerful fan to properly distribute the heat. Ceramic heater models that come with a fan and oscillating features tend to be a bit more expensive.
Despite what the name might suggest, oil heaters do not actually burn oil. Instead, an electrical element inside heats up the surrounding oil which then radiates warmth across the room. Think of oil-filled space heaters as an additional radiator that you can add to a large room.
So how does it perform as a large room space heater?
Well, they are extremely energy-efficient since the oil retains heat for a long time even after the heater has been switched off. Oil heaters don’t dry up the air or make any noise. And they are usually safe to touch which is an immense plus for households with pets and children.
However, the downside of an oil-filled heater for large room is that it might take a while for it to heat up the room. Since there is no fan, the warmth will gradually spread through the room instead of instantly blasting you in the face.
Micathermic heaters for large rooms combine the best of both worlds – convection and radiant heating. This 2-in-1 design makes them more efficient at warming up large rooms in comparison to other electric space heaters.
Just as radiant heaters, a micathermic one emulates sunlight and heats up objects in the room. But they also manage to warm up the surrounding air with the use of a fan. This ensures a superb distribution of heat throughout the room.
Their fast heating mechanism makes them power-efficient and the absence of a fan ensures a near-silent operation. Micathermic electric space heaters tend to be thin and can be wall-mounted.
Choosing an appropriate wattage of a space heater for large rooms
All room heaters have a specified wattage. Wattage indicates the amount of electricity needed to power the heater. But it does not specify the amount of heat it can deliver. As we’ve established above different types of indoor electric heaters can be more or less efficient in delivering heat.
Still, you can use the wattage to determine if the heater of your choice will be the best space heater for your large room.
However, before we dive into calculating the number of square feet a heater can warm-up based on its wattage we need to establish whether your heater will be a primary or supplemental heat source.
In a room with no central heating, an efficient space heater will be acting as a primary heat source. This also means that the heater will have to work a lot harder to raise the overall temperature of the room.
In the case of a heater being the primary heating source, you can say that it will roughly need 10 watts of heating power for every sq. ft. So a 1500-watt heater can serve as a primary heat source for a 150 sq. ft. room, a 2000-watt one – 200 sq. ft., and so on.
Now, this is just a bare minimum estimate. The type of heater, the level of room insulation, and ceiling height can significantly swing that estimate in both directions.
Things look a lot different if your electric space heater is acting as a supplemental heat source. Coupled with central heating, thermostat, furnaces, boilers, or anything else your large room space heater will be able to cover a lot more ground. A lot more.
Best space heater for large rooms: things to consider
Now that you know what type of large room space heater will be the best for you and how to match wattage to your sq. ft. it is time to take a look at other important things to keep in mind.
First, let’s talk safety.
For all of the electric heater’s ability to make you feel warm and toasty, don’t forget that it can still be hazardous. Any space heater is dealing with intense heat that, if improperly handled, can endanger your household.
Fortunately, most space heaters have appropriate safety features in place. Some of them are especially useful in a household with kids or pets. Here are the ones you need to keep in mind when choosing a large room space heater:
In order to protect you from accidental burns, space heaters come equipped with a heat-resistant surface. This keeps the heater’s exterior cool to the touch even when it is working hard to heat up your room.
Automatic tip-over switch
Even in a large spacious room, there is no guarantee that someone won’t accidentally tip over your electric space heater. Especially if it is a household with pets or kids that are too curious for their own good. Some electric heaters, such as a ceramic tower heater, are especially prone to this due to their tall vertical design.
But don’t worry, as long as your electric space heater has a tip-over protection safety feature you’re good to go with any tower heater.
This feature automatically turns off the heater if it gets knocked over. Some even manage to turn the heater off if it detects that it’s seating at an odd angle.
Automatic overheat protection switch
Every space heater with an overheat protection feature has a sensor that monitors its internal temperature. If for some reason, the heater reaches an unsafe temperature level, the sensor triggers an automatic shutoff.
There are some steps you can take to prevent the space heater from overheating. Make sure that it is situated in an open clear area with no obstructions and at least 3 feet from furniture, drapes, and so on.
Also, never use a space heater to dry clothes, socks, mittens, and other pieces of clothing. This can also cause the heater to overheat (although some electric heaters do come with a dedicated drying rack accessory).
Lastly, make sure that the heater is the only thing plugged into an outlet since they require high wattage. Also, never plug the heater for a large room into an extension cord. This can cause, the heater, plug, or cord to overheat, as well.
Not every space heater is suitable for a bathroom. However, some are specifically equipped for withstanding moist and damp environments.
If you need one make sure that the electric heater’s specifications state that it is safe for the bathroom and has appropriate safety features installed.
Heaters with UL, CSA, and ETL-Intertek certifications mean that they have been tested by a Nationally Recognized Testing Laboratory (NTRL). The certificate confirms that the space heater has been tested for hazardous or faulty electrical components.
Although you’re buying a large room heater to stay warm, you also want to ensure that the heating is as cost-effective as possible.
Be on the lookout for these features to ensure that the space heater of your choice is as efficient as possible.
A programmable thermostat can help you maintain the desired temperature in a large room. Space heaters with a thermostat, once they reach the temperature you’ve set, will shut off. Then they will cycle on and off to preserve that temperature.
This feature will help keep your electricity bills down since the heater will be running only as much as it needs to.
Some electric heaters come with some form of an eco or auto mode. These, as a rule, automatically regulate the fan speed to maintain your selected temperature.
So this feature also helps preserve energy and keep the fan from needlessly running when the room is already properly heated.
A programmable timer allows you to have your space heater turn off just when you need it to. This is not only convenient but also allows you to save money.
Energy-efficient type of heater
As we’ve mentioned before, some types of electric heaters are more energy-efficient than others.
If you need your heater to be as economical as possible, look into oil-filled, micathermic, and ceramic room heaters.
How to calculate space heater costs
You can actually calculate how much your large room heater will bump up your electricity bill.
The easiest formula to calculate how much running an electric heater will cost looks like this:
price per kilowatt-hour (cents/kWh) x heater runtime (hours) x kilowatts used per hour = price of running a heater (cents/day)
Let’s break down every part of this formula:
- price per kilowatt-hour – this is a standard price of electricity. You can either check it online or calculate it based on your current electricity bill using this method.
- heater runtime – the amount of time the heater will be running for. This will, of course, vary not only based on your personal preferences but the type of heater you have. Some heat up a lot faster and retain the set temperature for longer than others. You can consult the “Types of electric space heaters for large rooms” to find out more.
- kilowatts used per hour – to get this figure take the maximum wattage of the heater (most indoor space heaters suitable for a large room count between 1500 watts and 2000 watts) and divide it by 1000.
Example: 11 cents/kWh x 5 hours x 1.5 kW/hour = 83 cents per day
How to make your space heater more energy efficient
Your fan-equipped space heater will have to run for a lot longer if your large room has high ceilings. After all, in rooms like these, there’s a lot more cold air that needs to be heated up.
If you are working with large room space, the best space heater for you is an infrared or a micathermic heater. Both of these rely on radiant heating which warms objects and not the air.
Poorly insulated windows can let a steady flow of cold drafts in. This, of course, interferes with the heater’s ability to properly warm up a large space.
You should insulate your windows either way, especially before winter. The easiest way to do this is to use a shrink-film kit – all you need is a hairdryer and a couple of minutes. This will not only insulate a large space but also help your heater run more efficiently.
Don’t let heated-up air escape by keeping your doors open. Close the doors to the large space you’re heating to make sure the warmed-up air stays there. This will also help the heater run more cost-efficiently by only maintaining the temperature instead of constantly battling with cold air from other rooms.
Timer, thermostat, ECO mode
Take full advantage of the features your space heater has to offer. Instead of running the heater while you sleep (which is not recommended), set a timer to shut it off an hour after you’ve fallen asleep.
Use the auto/eco mode on your space heater to have the fan circulate between low and high settings to save on electricity bills. The same goes for the programmable thermostat.
One of these room heaters will help you warm up a large room or a studio apartment.
A carefully chosen space heater, be it a ceramic tower heater or an infrared heater, can not only help you stay toasty but also improve your health, productivity, and mood.
And by following our tips on energy efficiency, you can choose the one that will not strongly affect your electricity bills.
