Commercial Warm Air Heating Systems
A perfect and effective form of heating for large open-plan commercial and industrial spaces such as factories, warehouses, and distribution centres.
OKEL’s warm air heaters are available as either Natural Gas, LPG, or Electric fuel types, and enable large open-plan spaces to be heated more efficiently and effectively than with any other comparable method.
Warm air heating provides an even distribution of heat throughout the whole surrounding area to provide a comfortable working environment and one that minimises hot and cold spots, unlike radiant heaters which are rarely appropriate for these larger premises due to floor coverage.
Why Choose Us?
With decades of combined experience in the commercial heating industry, we understand that no two premises are alike.
The specific requirements needed by each industrial or commercial building can make a huge difference to the type of heating solution that will be both cost-effective and energy efficient.
Every new installation begins with a detailed site inspection by a member of our team to assess the building and to determine the individual needs of your business.
We carefully consider operational and environmental factors before handing off to our design team to put together a hand-tailored warm air heating solution that meets all your unique requirements.
When you appoint OKEL to deliver your warm air system installation, you are assured a personal approach.
You will be assigned your own project manager who will be your single point of contact throughout the installation process.
This ensures you will be kept informed of all important developments from the initial consultation through to the final handover of the project.
Our installation teams consist of both Gas Safe and NICEIC commercial heating engineers and whether you are wanting a warm air heating system fuelled by natural gas / LPG or perhaps considering a move away from gas and to an electrically powered warm air alternative, we have a warm air heating system to suit you.
We take on all manner of warm air heating system projects, for companies large and small. However extensive the job, you can depend on us to provide the same high standard of service.
We have worked with SMEs operating at a local level, as well as national blue-chip companies. We always deliver quality installations, and your project will be no exception.
One of the most efficient ways to warm up factories or warehouses, as well as large-scale retail premises, is the installation of warm air heating systems. We are committed to providing our clients with solutions that help to minimise both their energy costs and their environmental impact.
Each of our warm air heater models are ERP compliant in accordance with the latest eco design directive and fully modulating which means the heaters will only use the amount of gas necessary to maintain the desired temperature throughout the working day. See how we helped Fortress Technology Europe support its commitment to the environment, with our electrical warm air heaters.
Every one of our commercial heating engineers has been part of the industry for a minimum of 20 years and are fully trained and qualified to deliver exceptional results.
As well as having relevant, hands-on experience in their field of expertise, they are all registered with the relevant regulatory bodies for the heating industry, including GasSafe, and NICEIC.
What are the Benefits?
- Cost effective - 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.
- Quick and efficient heating - 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.
- Low noise levels - 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.
- Versatile installation - 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.

Types of Warm Air Heaters Used by OKEL
We use a variety of heating appliances for our commercial warm-air heating solutions, depending on the specific needs of your business. Offering ERP-compliant heater models, in accordance with the latest Eco Design Directive, and with the aim being to reduce negative environmental impact throughout the product life cycle. They incorporate modulating premix burners and fans to reduce energy consumption and are self-modulating.
This allows the heaters to quickly bring up the temperature in the building by operating at maximum load, before reducing their output down by approximately 60% to maintain the optimal temperature, while reducing energy consumption.
We supply and install wall-mounted/suspended or floor-standing heater models for any size of commercial or industrial premises, ranging from 10 to 150 kw. While our most popular models have been natural gas and LPG fuel types, we also install electric-powered warm air heaters and have seen an increase in demand for the electric model in recent years.

Our Installation Process
FAQ's
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.
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.
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.
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.
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.
Depending on the size of the area to be heated and 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.
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 manufactures 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.
