What are warm air systems?

Warm air heating systems explained

Whilst most heating systems in UK homes are via a gas fired boiler. Warm air heating is another cost-effective way to heat your home.

Warm air heating systems use a vent to extract air from outside which is then heated over a gas flame. The warm air then circulates via ducts throughout your home.

Most warm air systems are gas fired, however, heat pumps can also power warm air systems.

During the 1960’s and 70’s warm air systems were commonly installed due to their reliability and ease of installation. With a warm air system there is no need for pipes and radiators to be installed within the home. This is particularly beneficial for those who live in a smaller home as it negates the need for bulky radiators. A modern warm air system is highly efficient and very quiet in operation. Modern warm air systems can also have an electronic air filter fitted to remove potentially irritating airborne particles such as pollen, hair and bacteria. This can be very effective for those with allergies.

Unfortunately, a big disadvantage of warm air heating is that the majority of the systems don’t provide hot water.  Therefore, either a gas boiler or immersion heater would need to provide your hot water.

Furthermore, the vents within your home can provide an opportunity for drafts to circulate.

Unlike gas and oil-fired boilers, warm air heating systems have extremely limited options for controlling the heating, this can also put people off.

Maintenance of warm air heating

Like their gas boiler counterparts warm air heating will still need to be serviced on an annual basis by a gas safe engineer.  The engineer will need the relevant warm air qualification as well as experience with this type of heating.

Failure to invest in regular servicing means the warm air which is continually being blown around can lead to an accumulation of dust and debris. If left this can cause a breakdown as during the service the engineer will clean out all the relevant components to keep the system working efficiently.

Replacing warm air heating systems

Most UK homes now rely on a gas boiler for their heating and hot water.  This means there are fewer warm air engineers as well as fewer manufactures compared to gas boilers.

Homeowners looking to replace their warm air heating system will often choose to a ‘wet heating system’ with a modern gas boiler and radiators.  This tends to be a much simpler installation and provides an efficient and cost-effective means of providing heat and hot water to your home.
