Warm Air Heating Explained
An effective form of heating for large open-plan commercial and industrial spaces such as factories, warehouses, and distribution centres.
The running costs of a commercial warm air heating system tends to be considerably lower than any reasonable alternatives. They are highly energy-efficient, which means that fuel consumption (and its associated costs) is kept to a minimum.
Warm air heater systems are not just efficient in terms of energy consumption, they also work quicker than any other method at heating up open spaces. They warm the air directly, meaning a large space can be heated much quicker than relying on convection heat from a radiator or other central heating fixture.
Keep noise pollution to a minimum with a warm air heating system, one of the quietest heating solutions on the market. Ideal in a busy workplace, where people may need to make themselves heard for safety reasons.
There are many ways to install a commercial warm air heating system, from floor mounted cabinet style units to our most popular wall and ceiling mounted heaters. This gives our designers a lot of scope for producing the most efficient system possible.

Our Warm Air System Installation Process
On-Site Consultation
One of our expert engineers will visit your site to perform a free survey and discuss your unique requirements to find the right warm air heating system for you. They will be your point of contact throughout the installation process.
Solutions and Quotations
Based on our survey and your property’s needs, we’ll provide a custom design for an energy-efficient, cost-effective heating system. Your project manager will then review the solution and forecast how much it is likely to cost to be installed.
Pre-Installation Planning
Before installation begins, we perform detailed risk assessments and schedule the installation to minimise disruption as much as possible. We take the safety of our engineers and clients very seriously, which is reflected in our planning process.
Installation
Our team of fully accredited and highly experienced engineers deliver a safe, reliable and streamlined installation for your warm air system. The size of the building and complexity of the system will affect the time it takes to complete the installation.

Ongoing Aftercare
We offer full warranty protection as well as an annual maintenance service to keep your heating system in top condition.

Frequently Asked Questions
- What is a Commercial Warm Air Heating System?
As the name implies, a commercial warm air heating system directly warms the air in a commercial or industrial building, rather than heating radiators via a boiler-powered central heating system.
- Who Uses a Commercial Warm Air System?
All kinds of industrial and commercial companies make use of warm air heaters. They are designed for larger open plan buildings that contain a lot of empty space, such as production lines, factories, and warehouses.
They can also be fitted into sports centres, indoor arenas, theatres, and other premises that cannot be warmed efficiently via central heating.
- Why so I Need to Install a Commercial Warm Air System?
Large buildings tend to feel the cold, as it is difficult to warm up the air within via traditional radiant heat methods, such as central heating or body warmth.
If you want your staff to operate effectively, particularly during the colder months, you need an efficient way to warm your premises without spending a fortune on energy costs. Warm air heating systems provide the perfect solution.
- Who can Install a Commercial Warm Air System?
The installation of your warm air heating system will be dependent on your chosen fuel type, whether this be natural gas, LPG, electric or oil.
Your installer must be suitably trained, qualified, and approved to install and commission your chosen fuel type and able to do so in commercial properties – a domestic engineer will not have the relevant insurance or accreditations to work on more complex commercial and industrial installations.
- How Much Does a Commercial Warm Air System Cost?
That depends entirely on the size of the premises and site-specific factors discussed during the initial consultation process. Different premises require different set-ups to achieve the same desired result, making it impossible to provide an estimate for costs without a full site analysis.
- How Long Does a Commercial Warm Air System Installation Take?
Depending on the size of the area to be heated and the complexity of the system, installations can take anything from a few days to several weeks to install.
If your commercial or industrial property is in active use, it can take a little longer, as we do all we can to work around your employees so that we can minimise any disruption to your day-to-day business.
- How Long Does a Commercial Warm Air System Last For?
All our warm air heating systems are made of quality components and designed to last. Most of the equipment we use comes with a lengthy manufacturer’s warranty, often up to ten years. If you keep your heaters serviced and maintained regularly, you can expect them to last almost twice as long.
