Best Space Heaters for Large RoomsAlmost everybody thinks that winter is a bad time, and it is the worst when the cold is perpetual. For many years space heaters have been a constant companion of every household in the colder areas. Therefore, having a space heater for large rooms provides the best experience, is a must for all.

But in this modern age, when there are hundreds of brands in the market, choosing the best one becomes a tough work. So, to ease your problem, we have come up with some of the best space heaters for a large room that will suit your needs.

What is a Space Heater?

The answer to this question lies in the word itself. This device warms up your surrounding environment and keeps you away from freezing to death in some cases. Space heaters are mainly powered by electricity or burnable fuels like gas, propane or oil.

Importance of Space Heaters

The importance of space heaters cannot be described in a word.  From safety to affordability, space heaters beat all other types of heaters. Such as:

  • Space heaters are the most practical product in terms of affordability.
  • If you live in a colder area, having a space heater is essential for saving your life.
  • Space heaters keep your room warm and livable. And when you do not suffer in cold, you will always be in a good mood.

When it comes to purchasing a space heater, you will be faced with making a decision – what purpose do you want the heater to serve. Keeping that in mind, space heaters mainly fall into two categories –

    1. Convection Space Heaters
    2. Radiant Space Heaters
  • Convection Space Heaters: If you are looking for a heater to warm up your room for a long period of time, I would suggest that you go with a convection heater. Most heaters are convection heaters. These types of heaters need the circulation of the air in order to warm up the room. The cold air passes through the coil of the heater and comes out as warm. Since convection heaters heat up the air, the warmth tends to stay for a longer period of time. Also, these heaters make sure that the heat is distributed in the space evenly.
  • Radiant space heaters: Unlike convection space heaters, radiant space heaters are used to warm up a person or an object. The name “radiant’’ gives away how it works. It operates by emitting infrared radiation. The infrared contains energy that is absorbed directly by an object. Therefore, radiant heaters do not warm up the air of the room; rather they provide direct heat to a person. One of the basic advantages of using a radiant heater is that it warms you up very quickly, as the heat does not lose energy while traveling to you.

Apart from that, space heaters can also fall into two categories depending on what kind of fuel they use to operate – electric space heaters and gas heaters.

  • Electric space heaters: Electric space heaters are the type of heaters that use electric current to generate heat. Every electric heater uses a simple technique called “joule heating”. In this process, the electric current is passed through a wire coil, which is a resistor. The resistor then converts the electric current as heat energy.
  • Gas heaters: As the name says, gas heaters operate by burning gas. There is a heat exchanger inside the heater. The heat exchanger is heated with gas combustion. The cold air is passed over this exchanger and warm air comes out.

Things to Consider Before Buying a Large Room Space Heater

Before buying the best space heater, the first thing you need to consider is the size of the room. Is the heater efficient enough to cover the whole space? Is your room too small? These are the questions you need to answer before buying a space heater. Because buying a large heater for a small room will be just money down the drain.
Think about what kind of fuel the heater needs. Is it an electric or a gas model? You also need to consider what kind of fuel costs less. Before buying a space heater, make sure you read the installation manual. From that, you will have a clear idea about how to set up the heater and what should be done to set a heater up.
Some heaters are wall-mounted, while others are floor mounted. You need to check it before buying the best space heater. If you do not have enough space on the wall, then a wall mounted space heater is probably not the right choice for you. Also, if there is no option on the wall to plug the heater in, then it will be futile to buy a wall mounted space heater.
Check whether your heater has a thermostat. The thermostat lets you know if the heater gets overheated. They also make sure that you have an optimal temperature.
Like many electric devices, space heaters also make some noise. It is mainly because of the fan inside the heater that circulates the air. Make sure that your heater makes minimum noise. Many models also have features like an oil-filled radiator for silent operation. You can consider those models for your home or quiet environment.
One of the most important things to consider before buying a large space heater is whether the heater has a temperature control system. Many old models do not have this feature. But almost all new heaters come with this feature. Make sure you buy one which lets you control the temperature digitally.
Every good space heater has a feature that lets you set the timer. It is essential because it eases your monitoring and controlling of the heater. The timer also helps you minimize cost because if you set the timer, the heat starts or stops according to your time, without running for all day long.
The design of your preferred heater is an important factor you must consider. Not every heater is designed for the home environment; some are designed for commercial purposes too. So make sure you find the most suitable one for your home. You also need to check if the heater is designed to be mobile or not.
If you do not monitor your heater properly, chances are the heater will burst and cause a fire. Therefore, always look for a heater that is safe and sound for your home. Read the manual before buying, ask whether the heater has a sensor that can detect overheat or not. Also, check whether the heater has a cool-to-touch feature. These are the safety features that you need to consider while buying a large space heater.
Warranty is an essential factor for consideration. Not all large space heaters come with a long warranty. You need to make sure that the heater you are going to buy gives a warranty for a longer period of time. A warranty shows the durability of a product. It also says that the company is confident enough about its product.
