What you need to know about indoor heaters

When it comes to heating large rooms, there are three main types of heaters you need to consider:

  • Radiant heaters
  • Convection heaters
  • Combination heaters

Radiant heaters are powered by electricity or fuel. They work more of like the sun, by radiating heat outwards. These heaters heat in directions to which they are pointed to. They work best in warming objects rather than whole spaces.

Convection heaters work by creating air circulation. They rely on the natural flow of air, as hot air rises out of the heater, it creates a vacuum for cold air to be sucked in. These types of heaters are designed to heat the entire room because they heat the air rather than specific objects.

Combination heaters are a combination of the radiant and convection heaters. They use fans to circulate the hot air produced.

There are four main designs of this heater:

  • Wall heaters
  • Baseboard heaters
  • Freestanding heaters
  • Electric fireplace heaters

Wall heaters can be built in just fitted directly on the walls of rooms. The installation process is easy and efficient.

Baseboard heaters are generally small heaters which saves space due to their sizes, despite their sizes they are efficient. They are either built in the walls or can just be placed the floor beside the walls.

Electric fireplace heaters are heaters that use electricity to give an imitation of the traditional fireplace heaters with the traditional appearances.

The freestanding heater is the most common heater used. It uses the conventional principle to warm houses. It is a free-standing portable heater.

Factors you should consider while choosing an indoor large room heater

The first and most important factor is power. Here, you will consider according to the size of your room, in general, 10 watts heats 1 square foot space. So, you will need to measure the size of your room and find a heater with the capacity to heat it up.

Secondly, think about the utility of the heater. Under this, you consider fuel consumption and safety precautions. If you choose gas heaters, like propane tank heaters it might not be appropriate for those with small children. Also, the cost to install gas pipes in your house tends to be expensive. Electric heaters tend to be cheaper and safer.

Alternatively, it’s advisable to consider the space. Are you looking to recess something into the wall or to have an aesthetically pleasing fireplace?

You may be looking to have a surface wall heater that you can tilt for workshops or garages. A freestanding heater might be appropriate for this need because you can easily move it from room to room. Understanding the design will help you narrow down your choices.

Some added features such as a built-in thermostat, adjustable fan, remote controller, cool touch exterior, automatic tip over and wheels, may also be necessary to consider.

Safety considerations

Safety is a very crucial consideration. It should be given a very high priority while choosing an indoor heater. First, you should ensure the product has been tested for safety. Look for a safety label from a recognized testing lab such as UL (Underwriters Laboratory) to verify the safety of the product.

Next, consider the safety features that are associated with the heater. Like the cool-touch exterior which will stop the outside of the heater from getting hot and posing fire risks. You will find some heaters will switch off when the heater starts to overheat, while others will automatically turn off if the heater tips over.

On the other hand, you will find a great and often forgotten safety feature on the gas heaters. It is a carbon monoxide-related feature that switches the heater off when there is no enough oxygen for combustion in the room. It prevents carbon monoxide from being formed. When using gas heaters in your rooms, ensure you have a vented combustion heater; unvented heaters can be very dangerous.

I would like to briefly cite the best brands under the five discussed indoor heaters. I will generally give different brands and companies that manufacture them. Hoping that from the statements you can choose your product by going for the brand of your taste.

Frequently Asked Questions (FAQs)

How do indoor heaters work?

This is a frequently asked question when this topic is involved. An indoor heater is a portable device that is used to heat rooms or halls, such as living rooms and office spaces. Indoor heaters come in two main types: electric and fuel powered (natural gas, kerosene or propane). Electric heaters work with the joule heating principle, which occurs when an electric current travels over a conductor and produces heat. Most electric heaters use a built-in fan to distribute the heat more evenly.

Fuel heaters are mostly used as a backup heating source because they do not rely on electricity.

What kind of indoor heater is most suitable for large space rooms?

I can advise you to opt for an indoor heater that comes with a fan. This will help distribute the heat evenly in the large room. Furthermore, you can also place it under your working desk at a certain distance from your body. On the other hand, a floor standing indoor electric heater is also a good option for large room despite that it’s expensive, it’s efficient.

What is the most effective type of heating recommended for large space if one uses the Electric heater?

From the three mechanisms used on electric heaters, (radiant, convection and combined), the combined, also known as micathermic heating is the preferred selection. This is because it combines radiant and convection heating properties. The panel placed in front of the heater radiates the warmth across the room rather than focusing in a single direction.

What are the advantages of using an indoor heater for large rooms?

The main purpose of bringing in indoor heaters is to provide warmth during the cold seasons or chilly mornings. To be particular, these heaters spread heat to all corners of the room making it conducive to work in or spend time in.

What should you consider while buying an indoor heater?

The most basic consideration is the size of your room, this is because these heaters are designed to cover specific volumes. They are rated in watts.

Also, you need to consider the cost and choose one that favors your pocket. So that buying it doesn’t drain your accounts. You need also to consider the brands.

How much power is needed to power the indoor heater?

Amount of power that is needed varies with the power rating of the Heater and also the duration that the heater is to be powered on.

If you just want to heat a single room, you will need to calculate the power consumed of that specific room.

On the other hand, if you want to take the heater from room to room, you should look out for the heaters that have variable power options so that you can conserve energy when you don’t need the heater to be so powerful.
