Buying Guide: How to Choose the Best Space Heater for a Large Room?

Why You Should Invest in Indoor Space Heaters?

Having proper heating in your home is one of the most important things to have a comfortable and pleasant life during cold weather.

But, you need to pay attention to certain factors when you need to buy an indoor heater whether it is a large room or a small one. Here are the main factors that you need to take into consideration before investing in high-quality indoor heating for large rooms.


The Indoor Heater Will Save Your Money

By using the indoor heaters you can heat up only the specific areas in your home that you need. This is one of the biggest positive things about an indoor heater. In this way, you will be able to save a lot of money. For example, if you are using central heating in cold times it will heat up the entire your home even those areas that you don’t need to be heated.

But, the indoor heater you can place only in those areas where you want to be heated. So, from one side you will control the temperature in your home and from another side, you will control your bills. In the end, it makes no sense to heat the whole house during cold times if you don’t have a need to use some of the rooms. So, the indoor heater will allow you to keep warm only those rooms that you are using.


Great Portability

The portability is what gives an advantage of the indoor heater for large rooms over the central heating. You can easily move the heater everywhere around your house.

Some of the heaters for large rooms will be a little bit bigger in size and heavier. But, even these heaters can be moved around your home without a big problem by using wheels. You will only have a problem with moving those indoor heaters that are mounted on the wall.


Ability to Quickly Warm Up Your Room

When we talk about the speed of heating it is obvious that the central heating needs a longer time to heat the rooms in your home. Those who are using central heating know that you will need to set up a timer for the thermostat if you want the temperature in the rooms in your home to reach the desired temperature at a certain time. But, the indoor heaters don’t have that negative feature.

This is another positive thing about the indoor heaters and they are able quickly to heat any room in your house. But you need to know the speed of heating will differ in the model that you will buy. However, one thing is for sure, any model of the indoor heaters can quickly warm up your place


You Can Warm Up Places without Central Heating in Your Home

But, the real truth is that even the central heating is not able to heat all areas in your house. For example, in many homes, the garage is a place where there is no central heating. In most cases, during the wintertime, some people have a need to work in their garages. If you have an indoor heater, you can easily move it in your garage and make that place warm and comfortable for work.


RELATED: How Many BTUs is a 1500 Watt Heater?

What Are the Different Types of Space Heaters?

The indoor heaters can be classified into two major groups: the way how space heaters heat the air and the type of fuel they use.


The Way How Space Heaters Heat the Air

When talking about how the air can be heated in your room, the heaters are divided into three main groups: Radiant, Convective and Micathermic Heaters.


Radiant Space Heaters

Radian heaters heat the air in a very simple way, which is the transmission of heat into the infrared spectrum. In this way, the objects in the room are heated directly, without heating the air in the room.

This way of heating is very energy efficient because the heat is directly transferred to the objects with a very low loss rate. Because the heat is directly transmitted to the objects, there is a very low loss rate of energy which makes this way of heating highly energy-efficient.


Convection Space Heaters

Convective space heaters are a type of heaters that use a type of heating element to heat the air in your room. The heating element in most cases can be ceramic plates, diathermic oil or sometimes water. Once the air is heated by means of the heating element, it is then delivered back to the room by means of a fan. Some convective heaters have an oscillator built-in to help spread the warm air into the room.

Depending on the heating element used inside the convective heaters they are divided into 5 different types: ceramic heaters, oil-filled heaters, water-filled heaters, fan heaters, and furnace heaters. The oil-filled heaters need some time to heat up which is one of the disadvantages but from the other side, their surface remains cold to touch.


Micathermic Heaters

Micathermic heaters are some type of hybrid heaters when it comes to heat delivery. They have the ability to produce both radial and convective heat. Their way of producing heat is quite different from other types of space heaters.

They use mica panels to deliver space heat and the process of generating and delivering heat is simple. The heating elements are surrounded by mica panels. By switching on the heater, the heated elements heat the mica panels which then quickly deliver heat to the room in the form of electromagnetic rays similar to infrared heaters.


Space Heaters Based On the Type of Fuel They Use

Furthermore, depending on the type of fuel used by the heaters, they can be divided into several groups:

  • Electric Space Heaters: This type of heaters is using electricity as a power. The electric space heaters can be used to support the central heating system or separately for zone heating.
  • Natural Gas Heaters: instead of electricity this heater is using natural gas as fuel. These types of heaters are one of the cheapest options for heating your home and they are easy for installing.
  • Kerosene Heaters: Space heaters that use kerosene is another cheap and powerful solution to heat your home. Mostly they are used in workplaces.
  • Propane Heaters: using propane heaters are also a cheap way to heat a home.
  • Pellet Heaters: Space heaters that use pellets as a fuel is a cheap and powerful solution for efficiently heating up the entire home.
  • Oil-Filled Heaters: These heaters use electricity as a power supply. Even after they are turned off, they can deliver heat within a certain period of time, thanks to the heating element inside them. How long these heaters can deliver heat after shutdown, will depend on the type of heating element installed in the heater itself.
  • Hydronic Heaters: This is a heating system consisting of a water heater and heaters installed throughout your home. The boiler heats the water, which then passes through the heaters and heats them. Then, heated heaters deliver heat throughout the home.

As you can see, you have many types of space heaters with a different usage of fuel. It is up to you what type of space heater you will choose to heat up your home. Every type of space heater and the type of fuel that is used in it has its own advantages and disadvantages.

The Pros and Cons of Different Space Heaters

Now, let’s have a look shortly at some popular types of space heaters such as infrared, oil-filled, ceramic and micathermic space heaters and see what are their major advantages and disadvantages:


Pros of Infrared Heaters

Fast Heating: Infrared heaters have the ability to quickly heat the room in which they are located.

You do not have to wait for your room to get warm; the heating process is almost instant. This means that infrared heaters are energy efficient.

They Do Not Affect Humidity: One of the very positive things about infrared heaters is that when in use they do not affect the air humidity in the room at all, because the heat is directly transmitted to the objects.

This is of paramount importance to those who grow plants in their homes because the plants need a humid environment. It is also worth noting that there will be no damage to the wooden furniture in your home.

Positive Impact on Your Health: On the other hand, infrared heat has a positive impact on your health such as increasing the immune system of the body and increasing the circulation of the blood. Simply put, you will have all the positive benefits of sunlight, but without the harmful UV radiation.

Budget-Friendly: The cost of using electric infrared heaters is much lower than convective heaters. They use less energy to heat the room in which they are located; in fact, infrared heaters consume almost twice less electricity than other types of heaters to produce the same amount of heat. This means that over the long term infrared heaters are cheaper to use.

They Require Low Maintenance: electric infrared heaters are easy to maintain.


Cons of Infrared Heaters

You Must Be Close: If you want to benefit from infrared heat you need to be in their immediate vicinity.

They Emit a Red Light: Because infrared heaters emit red light while working, it is not recommended to use in rooms where there are people who may be irritated by their light, especially in the bedroom when they are sleeping at night.

After Turning Off the Infrared Heater the Heat Disappears Quickly: Because of the ability of the infrared heaters directly to transfer the heat to the objects without heating the air, once you turn them off the heat will quickly disappear in the room.

Not for Large Spaces: They are not the best choice if you need to heat up large areas.


Pros of Convective Heaters

Great Portability: Ceramic heaters have great portability due to their compact dimensions. This allows you to easily move them around your house as needed.

If you really need a portable space heater with compact dimensions, then a ceramic heater might be the right choice for you.

They Offer Instant Heating: Generally, ceramic heaters use a fan to move the heated air through the room in which they are located. This allows you to warm up the room you are in for a very short period of time.

Perfect for Small Spaces: If you need to warm a small room, you can achieve this very efficiently and effectively by using a ceramic heater.

Not Expensive: Ceramic heaters can be found at very affordable prices.


Cons of Convective Heaters

Noise: It is obvious that every type of heater that uses a fan produces a certain level of noise. This also applies to ceramic heaters, they are considered as noisy devices. Some of them create a higher level of noise, while some ceramic heaters produce less noise.

If you are interested in the noise level of a particular model of a ceramic heater, you should check its specification that indicates its noise level, and also check if the heater has settings for additional fan speed control. If you are one of those who prefer silence in their home, then I recommend choosing an oil-filled heater or infrared electric heater, especially as the quietest are oil-filled heaters.

Maintenance: Another disadvantage of this type of heater is maintenance. You should occasionally clean the heater, especially the blades of the fan to remove the dust and other small particles. You don’t want dust into the air in your room.

First of all, no one wants to inhale dust, especially people who have problems with asthma and allergies. For people who have problems with asthma and allergies and need a space heater, the best solution is an oil-filled heater.


What Are the Benefits of Oil-Filled Heaters?

They Are Quiet: The oil-filled heaters are pretty quiet devices. Usually, oil-filled heaters do not use fans to distribute heat to the premises where they are located.

The heated oil in the heater has the ability to slowly release heat into the room which means they almost never produce any noise. Because of this, these types of heaters are most suitable for indoors where you want no noise, especially in a bedroom where you need complete silence while sleeping.

Oil-Filled Heater Can Produce Heat Even after You Turn It Off: Once the oil-filled heater is turned off, the heated oil does not cool rapidly, meaning it will still emit heat for a period of time.

This is another positive feature of this type of heater that will be of great benefit to people who do not want their heater turned on at night and want to have a longer period of heat late at night while sleeping.

Great Choice for People with Allergies: They don’t use a fan to move the heated air in the room


Cons of Oil-Filled Heaters

Less Portable: Oil-filled heaters are heavier than other types of heaters. It will be a little harder to move a heater of this type from one location to another. Their weight makes them less portable than other types of heaters.

With the intention of slightly increasing the portability of these heaters, most of them come with built-in wheels to facilitate their movement from one location to another. However, oil-filled heaters are less portable than infrared heaters and most ceramic space heaters.

Slow Heating Abilities: The oil-filled space heaters need time to heat up before they start delivering heat in the space. In most cases, you will need between 15 to 20 minutes before you feel the heat in your room.

This is not for people who want instant heat. If you are one of them then a better option for you is to purchase one of the infrared electric heaters who are able instantly to heat a room.


Pros of Micathermic Heaters

Silent Operation: Because micathermic heaters don’t use a fan, they don’t make noise at all.

Fast Heating: Micathermic heaters have the ability to emit heat instantly when you turn them on, which is the same capability as infrared heaters. Unlike oil heaters, it takes about 15 to 20 minutes before they can effectively heat the environment.

They Are Lightweight: Micathermic heaters are by far lighter devices when compared to other types of space heaters such as infrared and oil-filled heaters.

High Portability: Due to its lightweight and ultra-slim design, micathermic heaters have great portability. You can transport them anywhere in your home with great ease. They are also an ideal solution if you want to have a space heater mounted on the wall.

100% Conversion of Electricity: Micathermic Heaters are capable of converting 100% of the input energy into heat. This makes them the most effective space heaters on the market. They are leaders when using less electricity than other types of space heaters.

Great Choice for People with Asthma and Allergies: It is known that space heaters that have a fan for moving warm air into the room, at the same time many of the allergens, bacteria, particles, and dust move with the air around the room. This is not the case with micathermic heaters, because they do not use a fan. Because of this, micathermic heaters are an ideal solution for people suffering from asthma and allergies.


Cons of Micathermic Heaters

Limited Heating Range: The downside of micathermic heaters is that they have a limited range of room heating. Their maximum range of effective room heating ranges from 150 to 200 square feet. This is due to the fact that they do not use a fan for better distribution of hot air.

Features to Look for While Buying a Space Heater

The Size of the Heater: On the market today, space heaters can be found in different sizes and with different heating power, the choice is really great.

The size of the space heater will depend on the size of the room you need to warm. If you need to heat a small room then it makes no sense to buy a large size heater with high heating power. On the one hand, you will spend more money and on the other, you will have bigger electricity bills.

In this case, it would be better to buy a smaller size space heater with a lower heating power. If you need to warm up a room with larger dimensions then it is normal to buy a space heater with higher heating power.

But, you should know that today the dimensions of the heater do not determine its heating power. Today’s newer space heaters are smaller in size and employ more advanced technology that gives them tremendous power of heating. Therefore, when choosing a space heater, always check its factory specifications to see if the power of heating of the heater will suit your heating needs. Typically their heating power varies from 750 to 1500 watts.

The Level of Noise: Space heaters are usually very quiet devices, like for example, most oil-filled, infrared and mica thermal heaters. Some heaters have a fan to allow better and faster hot air distribution in the room. So these heaters have a higher noise level. So, if you need a quiet space heater, then you should choose a heater with no fan.

Remote Control: Today, most space heaters come with remote control. It lets you manage settings for your device more easily from a distance.

Safety Features: When buying a space heater, always check if the model has all needed safety features like the following:

  • Over-tip Protection: this feature will detect when the heater is falling on the floor and at the same time automatically it will turn off the heater. This safety feature especially is useful if you have kids and pets in your home that can by accident push the heater to the floor.
  • Overheat Protection: this is a very useful feature and it automatically turns off the heater when its outer casing gets too hot to touch. So nobody will get burned which is also of great importance if you have kids and pets.

Portability: When buying a space heater, you need to consider whether or not you want your heater to be portable. Portability is also a very important factor that allows you to easily move the space heater from one place to another.

For greater portability, some heaters come with a built-in handle to easily take the heater where you need it or have mounted wheels that allow you to easily move it to a specific location. Also, some heaters have both features: a built-in handle and embedded wheels.

Thermostat: This is a great feature that you need to look for in a space heater. The thermostat will allow you to set your desired temperature that you want your heater to reach and maintain in your room.

Timer: The timer is a very useful and safe feature to look for in the space heater you want to buy. With the timer, you can simply adjust the heater how long it will work. After the set time elapses, the heater will automatically switch off.

Most of the space heaters come with an internal security timer that will automatically turn off the device if it operates continuously for 8, 10 and 12 hours. Certain models of space heaters will allow you to set working hours much longer.

Possibility of Mounting: Some space heaters have the option of being mounted on a wall or ceiling. They have small fixtures that allow you to hang or screw the heater on the wall. Normally with the heater comes a manual that gives you a step-by-step guide on how to do it.

This is a very handy thing if you are living in a small apartment where your space is limited, so mounting the heater on the wall or ceiling is a great solution. Those who have children and pets can also benefit from this. By mounting the space heater on the wall, it will be out of reach for children and pets.

The Length of the Power Cord: Before buying a space heater, check the length of its power cord. The longer the cable, the more flexibility you’ll have in positioning the space heater in your room.

Built-in handle: It is also very important if the space heater has a built-in handle. It will allow you to easily move the heater where you need it most.

Some Safety Tips about Space Heaters


  • No matter what type of space heater you decided to buy, always read the instructions for use carefully before its first use.

Some Frequently Asked Questions


If I leave the Space Heater On All Night, Is It Safe?

For safety reasons, the space heater is not recommended to operate overnight. If you leave the heater running at night while you sleep, you will be exposed to any potential risks. For more information on why you should not leave your space heater running all night, you can read here.


Is Infrared Heating Hazardous to Your Health or Not?

The answer to this question is simply no. Infrared heaters have no harmful effect on your health and the environment. These heaters emit infrared rays, which are actually the same rays that the sun emits. This radiation is not harmful at all and is completely different from X-rays or microwaves. Infrared radiation has all the benefits of sunlight without the harmful properties of UV rays. They have a positive effect on our skin and health.

The infrared rays of these heaters directly heat the objects and walls of the room. They do not heat the air, which means they do not reduce humidity in the room. Also, when operating infrared heaters, they do not move air into the room which means they do not spread dust, bacteria, and allergens around.


Do Space Heaters Emit Carbon Monoxide?

We all know that electric space heaters use electricity to generate heat as fuel. So it’s normal that they can’t emit carbon monoxide at all, so you don’t have to be afraid of carbon monoxide poisoning. Carbon monoxide can be emitted from space heaters that use wood, natural gas, kerosene, propane or some other type of fuel. The newer models of space heaters have built-in oxygen sensors. When the oxygen level will drop to a critical level, the heater will automatically switch off.


Are Space Heaters Safe for Kids?

It is known that when operating a space heater certain parts of its surface become hot. If you have children or pets in your home and want to use space heaters, you should know that there is a high risk of them to burn themselves by touching some of the heated parts of the heater.

But, today the housings of the newer space heaters are designed to stay cool to the touch no matter how long they work. In addition, they come with many advanced safety features such as automatic shutdown if overheating occurs, if you allow them to operate for longer than 8 hours continuously they will automatically shut off or if they are pushed to the floor they will automatically shut off.

Also for greater safety, most of the space heaters can be mounted on a wall or ceiling so they are out of reach of your children. However, despite all these safety features, some precautions should be taken. You should always set up a three-foot safety zone for your children and pets and monitor them frequently.
