How to choose a gas heater


As the summer months start to give way to the autumn-winter seasons, it's time to start thinking about changing the switch at home from cold to hot.

In other words, there is no time like the present when it comes to preparing your home for heating in the colder months of the year.

There are many different types of radiators to choose from. Depending on the specific needs of your home and your desired fuel source, one option may be better than another. Many people choose gas heaters, which are usually powered by liquid propane or natural gas, for their homes or other rooms.

These units are not one size fits all - there are many types with different characteristics, designed for different living spaces and needs.

Here we will disassemble several different types of gas heaters, how they work and for which rooms they are best suited. Knowing this information before buying can help you make an informed decision.

Types of gas heaters:

  • Ventilated heaters
  • Wall stoves
  • Heaters without vent
  • Blue flame
  • Infrared or Radiant

As the name suggests, gas heaters are different from their equivalents in terms of fuel type. While gas heating options are based on natural gas or liquid propane, others are powered by electricity or sometimes a combination of the two.

Even within this category, there are different subcategories from which you can choose. Below are some of the most frequently purchased gas heaters.

Ventilated heaters

Ventilated heaters are dynamic devices that can operate on natural gas or liquid propane, and are usually used inside the house to heat rooms from 300 square feet to 3000 square feet. While they are usually more expensive, ventilated heaters can often be a one-off solution. They are available in a variety of variations, such as wall or room heaters.

Wall-mounted heaters

Ventilated heaters, wall stoves are mounted between the wall plugs and the plasterboard of the room. They work by sucking in cool air from below, heating it and then blowing it out from above. Wall stoves are often used as accessories to houses, apartments or smaller houses.

Heaters without air vent

Do you have a sunny room or other room that requires some additional TLC heating? Gas-fired, ventless heaters are fantastic auxiliary heat sources, with a choice between blue flame and infrared or radiant heat. Ventless heaters are usually available in gas, liquid propane or dual fuel versions. They typically cover an area of about 200 to 1200 square feet.

Blue flame

The blue flame heater works, ultimately heating the air in the room where it is installed, not objects. Ideal for insulated rooms, blue flame heaters can last slightly longer and are a more energy efficient option. These economical devices usually operate at an efficiency of around 99.9%. These units are usually equipped with a blower that helps distribute the warm air throughout the space.

Infrared or Radiant

Unlike blue flame heaters, infrared heaters use electromagnetic radiation to heat objects in the home. This means that heat is transferred directly, which allows for much faster heat generation. However, for the same reason, infrared heaters require some additional safety measures because furniture, clothes and children should be kept at a reasonable distance from the heater itself, especially in case of malfunction.

At a high level, gas heaters and gas stoves work by igniting a number of burners in the combustion chamber. When a pilot light or a spark of a fuse is lit, the resulting heat is transferred to a heat exchanger which pushes the air and raises it to the desired temperature. The blowers then send air through ducts and to different rooms, or through the system to one room that is heated.

In these types of ovens, natural gas or liquid propane serves as an aid in lighting the above mentioned burners. Some furnaces are equipped with the possibility of using each of these types of fuel.
