Warm Air Heating System - 2023 Guide

If you’re unfamiliar with warm air heating systems, you’re not alone. More of these units have been replaced (in older properties 1970s) with improved boiler technology coupled with water-filled radiators. The replacement ones are more efficient and can be gas, electric and or hydrogen/hybrid boilers. However, if you are curious about this form of home comfort, we have some suggestions to help get you up to speed on all things related to warm air heating!

A warm air heating system can be a smart choice for those looking for affordable and efficient heating solutions. While suitable for various properties, they work perfectly in well-insulated single-story homes and commercial spaces.

What is warm air heating?

Warm air heating is a type of central heating system commonly used in the UK that works by heating air in a furnace or heat exchanger and then distributing the warm air throughout a building using ducts or vents. This is in contrast to traditional radiator-based heating systems, where hot water is circulated through pipes and radiators to provide warmth.

These systems work by drawing in air from the outside via a vent and passing it over a gas flame to generate warmth. The heated air is then circulated throughout the building. A thermostat controls the temperature to suit the living or working environment.

Warm air heating systems can be powered by a variety of fuels, including gas, oil, or electricity. They can provide quick and efficient heating and are often used in large commercial and industrial buildings as well as residential properties.

Types of warm air heating systems

There are several types of warm air heating systems commonly used, including:

Gas-fired warm air heaters: These are the UK's most popular type of warm air heating system. They work by burning gas to heat the air, which is then distributed through ducts or vents to provide warmth to the building.

Oil-fired warm air heaters: Like gas-fired systems, oil-fired warm air heaters burn oil to heat the air. They are less common than gas-fired systems but can be a good option for buildings not connected to the gas grid.

Electric warm air heaters: These systems use electricity to heat the air, making them a good option for buildings that do not have a gas or oil supply. However, they can be more expensive to run than gas or oil.

Heat pump warm air heaters: Heat pump systems use electricity to transfer heat from the outside air into the building. They are highly energy efficient but can be more expensive to install than other types of warm air heating systems.

The type of warm air heating system that is most suitable for a building will depend on the following factors:

Size of the building

Type of fuel available

Installation and

Running costs budget.

Are warm air systems any worth it?

One advantage of warm air systems is that they provide quick and efficient heating, as the air is heated directly and distributed throughout the building. This can make them a good option for buildings that require rapid heating or where traditional radiators may not be practical or efficient.

Benefits of domestic warm air heating.


Energy-efficiency household insurance policy. The cost of monthly premiums can seem daunting, so it's worth weighing up the monthly/annual expense against the potential costs of repairs or replacements without insurance.

Funding is accessible
To help the uptake of less carbon-intensive heating systems, including air-to-water, air-source heat pumps and ground-source heat pumps, the UK government will provide financial assistance in many situations.

Radiator free
Radiators are not always necessary because some warm air heating methods employ vents, ducts, and grilles instead.

Ability to operate quietly
Warm air heating systems are renowned for operating quietly, so you don't have to be concerned about noise levels.

Compatibility of heating controls
Warm air heating controls are compatible with electronic heating controls, allowing you to set consistent temperatures throughout your house and have more control over your heating.

Availability of electronic filtration
Electronic filtration eliminates nearly all airborne particles and irritants, including pollen, germs, and pet hair. A feature is available with warm air heating systems.


Warm heating systems provide many benefits, but they also have some drawbacks.

High start-up expenses
Installing a new warm air heating system might be expensive and out of reach for many households in the UK due to slow take up. Installation fees for ground source heat pumps might range anywhere between £15,000 - £19,000.

No hot water.
Hot water is not provided with warm air systems, which is a problem. So, a cylinder with an immersion heater is a must.

Limited options
Compared to the availability and variety of new gas boilers, you will find that warm air heating systems is less diversified and competitive. Costs can be expensive, and choices are limited because there aren't many manufacturers, installers or qualified engineers to service or repair them. If you need a qualified warm air engineer, then you’re in luck as serviceteam can provide one.

Visible ductwork and vents
The necessary ductwork and vents may be challenging to adapt to a property. These ducts are noticeable and could be unattractive. Usually, when a property is constructed with warm air in mind, the ducting is concealed within the fabric of the building, and the only visible signs would be the vents in each room.

Transport allergens
Warm air heating systems have the potential to spread allergens like dust and pollen throughout your house. Those who have allergies or lung issues may have a problem with this.

Warm air system Vs Radiator

Warm air systems can also be more versatile than traditional radiator-based systems. The ducts or vents used to distribute the heated air can be placed in a wider range of locations, allowing for more flexibility in the building design.

However, using a warm air system also has some potential disadvantages. These can include issues with air quality and ventilation, as well as the potential for noise from the system's fan or blower. Additionally, warm air system installation and maintenance costs can be higher than for a traditional radiator-based system.

Overall, whether or not a warm air system is a good choice for a particular building will depend on various factors, including the building's size and layout, the fuel source available, and the installation and running costs budget. It is always advisable to get a professional service and consult a heating engineer or HVAC specialist to determine the most appropriate heating system for a building.

Is warm air heating economical?

The economic efficiency of a warm air heating system will depend on several factors, including the type of fuel used, the system's efficiency, the building's size and layout, and its insulation.

In general, warm air heating systems can be economical for heating buildings, particularly in larger commercial or industrial settings. They can provide rapid and even heating and may be more versatile than traditional radiator-based systems.

However, the running costs of a warm air heating system can vary depending on the type of fuel/energy used. For example, gas-fired systems tend to be more economical than oil-fired systems. In contrast, electric systems can be more expensive to run.

The system's energy efficiency will also play a role in its economic efficiency. A system with a high-efficiency furnace or heat exchanger, for example, will be able to produce more heat from a given amount of fuel, leading to lower running costs.

Get professional support

As technology evolves rapidly, so does the demand for energy-efficient solutions. With talks of a ban on gas boilers (within new builds), other forms of heating are now being explored within the industry. Options such as hydrogen boilers, electric boilers, and going back to ground source heat pumps and air source heat pumps are all on the table for consideration. However, for the time being, gas boilers remain the most widely used form of heating for homeowners.
