Gas heaters are heating devices for heating a room or an outdoor area. To produce heat, a gas heater burns natural or liquefied petroleum gas.
Gas heaters have become a popular choice for heating Perth homes and businesses for years. It’s all thanks to their cost-efficiency and energy-saving qualities. If you’re considering installing a gas heater, this blog is for you.
This guide discusses everything you need to know about gas heaters, including the different types, maintenance requirements, and safety considerations.
Types of Gas Heaters in Australia
Preparing for the cooler months of the year includes installing a heater in your home. There are various gas heaters, and your decision primarily depends on your home’s needs. You may also have a preference when it comes to fuel sources. Gas heaters are not one-size-fits-all, as these types are designed with different features to suit specific living spaces and requirements.
Let us break down the gas heater types in Australia and how they work:
Gas Radiant Heaters
This type of gas heater generates heat through a process known as radiant heating. A radiant gas heater uses either natural gas or LPG to provide warmth through infrared or electromagnetic radiation emission. That’s why this type is also known as an infrared heater.
A radiant or infrared heater transfers heat, which is absorbed directly by the people and objects in the room. It does not heat the surrounding air, which makes it effective in heating the space much quicker.
Gas radiant heaters are excellent for patios and outdoor settings. They also work great in large indoor spaces like workshops and warehouses. That’s why they are often the preferred heating appliance in cafes and restaurants with outdoor seating.
Flued Gas Heaters
Like a radiant heater, flued gas heaters use LPG or natural gas. It is named so because this heater is designed with a chimney or flue that emits combustion gases and moisture outside the house. You don’t have to worry about indoor air quality with this heater.
Flued gas heaters can be:
- Wall-mounted flued heaters are installed on an external wall. They use a flue system to expel combustion gases, leading them outdoors. A wall-mounted flued heater is best for a small open-floor layout or a single room.
- Inbuilt flued heaters are connected to your existing fireplace opening. A cavity will be created for this specific purpose if you don’t have one.
This gas heater is prized for energy efficiency and offers consistent heat output.
Unflued Gas Heaters
Unflued, also known as portable or ventless, is a type of gas heater popularly used in many Perth homes. Unlike the flued version, this one does not require a flue. It is also not fixed in a certain spot, which allows homeowners to move the device between rooms as required.
Although convenient and easy to use, unflued gas heaters release combustion gases inside the house. Therefore, it is crucial to have adequate ventilation to avoid any unfortunate circumstances. Many unflued heaters have an oxygen depletion sensor (ODS), which controls the heater by shutting it off if oxygen levels are too low.
Unflued heaters are less expensive than installing flued gas heaters. However, you may require additional devices, including a gas leak detector and a carbon monoxide alarm, to ensure the household’s safety.
Gas Convection Heaters
Gas convection (or convector) heaters are gas heating appliances that work by drawing cool air from the room. They heat the air with a gas-powered heat exchanger before releasing the warmed-up air into the space. This simple cycle generates a continuous flow of warm air, providing the room with even and consistent heating.
A gas convector heater is energy efficient and heats the space quickly. It can be mounted on the wall to save floor space and offer targeted heating to a specific area in the house. The heater can also be freestanding in the form of a portable unit, which you can move from one room to another. Gas convectors can also be connected to a flue, which is useful in spaces with inadequate ventilation.
