Commercial Warm Air Heaters
Warm air heaters are the workhorse of warehouses, workshops, and industrial units. A heater that fails its annual check or breaks down in January stops work and leaves you with a gas appliance nobody has signed off as safe. Keeping them serviced and safe is both a legal duty and the difference between a warm building and a cold one.
At Robinsons Facilities Services, our Gas Safe registered engineers service, repair, and install commercial warm air heaters and air curtains across Yorkshire and the Humber. We price servicing per heater, so a site with several units knows exactly where it stands.
Annual servicing from £250+VAT per heater, with multi-heater discounts | Contracts from £385+VAT/year | Repairs from £80+VAT/hour

Commercial gas warm air heaters must legally be serviced and repaired by a Gas Safe registered engineer qualified for commercial appliances, under the Gas Safety (Installation and Use) Regulations 1998. Annual servicing is the recognised way to keep heaters safe, efficient, and insurable.
Your obligations for commercial warm air heaters
Gas warm air heaters are commercial gas appliances, and they carry the same duties as any other gas plant on your site. Under the Gas Safety (Installation and Use) Regulations 1998, all installation, servicing, and repair of gas appliances must be carried out by a Gas Safe registered engineer. Using an unregistered engineer is a criminal offence.
You also have a duty to keep the appliance in a safe condition. Annual servicing and a gas safety check are the recognised way to meet that duty, and most commercial property insurers require documented service records as a condition of cover. If you let the premises, an annual gas safety check on appliances you are responsible for is a legal requirement.
One point specific to warm air heaters: they need an engineer with the correct commercial gas qualifications. Domestic Gas Safe registration does not cover commercial warm air heaters, so it is worth checking your engineer holds the right categories. All our engineers who work on these appliances do.
Types of warm air heater we service
We service, repair, and install the full range of commercial warm air heating, including:
- Suspended gas-fired warm air heaters
- Floor-standing cabinet heaters
- Wall-mounted warm air heaters
- Air curtains and over-door heaters
- Destratification systems that recover warm air from high ceilings
Our engineers work across the major commercial warm air heater brands, including Powrmatic, Combat, Ambirad, Reznor, Benson, Nordair-Niche, and Roberts Gordon. If your heaters are from another manufacturer, contact us and we will confirm we can support them.
What a warm air heater service includes
A full service on a commercial warm air heater covers the safety and efficiency checks the appliance needs to stay compliant and run economically:
- Gas safety check and gas soundness testing
- Combustion analysis to confirm the burner is running cleanly and efficiently
- Flue inspection to confirm safe evacuation of combustion products
- Burner clean and inspection
- Fan, filter, and heat exchanger check
- Electrical safety and controls check
- Gas safety certificate on completion
This is why a proper service costs more than a quick visual check. The gas safety certificate it produces is your evidence of compliance for insurers and, where you let the premises, for your tenants.
Pricing
We price warm air heater servicing per heater, and the rate reduces where several are serviced in one visit, so a multi-unit warehouse pays less per heater than a single-unit site.

Planned servicing scheduled to your heaters’ annual gas safety intervals, with priority response and preferential repair rates.
Repairs — from £80+VAT/hour
Business-hours attendance to diagnose and repair a fault. Rate confirmed before the visit.
Installation — quoted after a site survey
New heaters and full replacements are quoted individually, since cost depends on heater type, number of units, and access. Fixed, itemised quote before any work begins.
How we support you

Commercial Warm Air Heaters FAQs
At Robinsons Facilities Services, warm air heater servicing starts from £250+VAT per heater, with multi-heater discounts where several units are serviced in the same visit. Heaters mounted high in a roof may need access equipment, which is quoted separately. Contact us on 01423 226578 with the number and type of heaters for a quote.
Commercial warm air heaters should be serviced at least once a year, in line with manufacturer guidance and to meet your duty to keep gas appliances in a safe condition. Annual servicing is also required by most commercial insurers, and where you let the premises an annual gas safety check is a legal requirement. Heaters in heavy or continuous use may need more frequent attention.
Yes. A gas warm air heater is a commercial gas appliance, so all work on it must be carried out by a Gas Safe registered engineer, and a service produces a gas safety certificate recording that the appliance is safe to use. This is your evidence of compliance for insurers and, where the premises are let, for tenants. The engineer must hold the correct commercial gas qualifications, which domestic Gas Safe registration does not include.
Yes. Many warm air heaters are suspended at high level, and where a heater sits above about 3.5 metres we use a MEWP or cherry picker for safe access. This adds to the cost of a visit, so we confirm whether access equipment is needed when we quote, rather than surprising you on the day.
Our engineers work across the major commercial warm air heater manufacturers, including Powrmatic, Combat, Ambirad, Reznor, Benson, Nordair-Niche, and Roberts Gordon. If your heaters are from a brand not listed here, contact us and we will confirm whether we can support them.
