Industrial Boiler Servicing

What is an Industrial Gas Boiler – and How Much Does a Service Cost?

Industrial gas boilers are essential to the operations of factories, warehouses, hospitals, schools, and large commercial buildings. These powerful systems supply consistent heating and hot water on a much larger scale than domestic or even commercial boilers.

In this article, we’ll explain what industrial boilers are, the cost of maintaining them, and why regular servicing is critical to teir safety, performance, and legal compliance.

What Is an Industrial Gas Boiler?

An industrial gas boiler is a high-capacity heating system designed to meet the large-scale demands of industrial or commercial premises. These boilers run on natural gas or LPG and are engineered to deliver outputs from 70 Kilowatts to over 50  Megawatts.

Typical features include:

• High-efficiency burners

• Large-volume heat exchangers

• Advanced controls and monitoring systems

• Integration with multiple heating zones or process lines

• Heavy-duty construction for continuous operation

Industrial boilers are typically installed in plants, manufacturing sites, hospitals, universities, and district heating networks, where reliability is critical and downtime can result in major disruption.

How Much Does an Industrial Boiler Service Cost?

The cost of servicing an industrial gas boiler depends on the boiler’s size, configuration, and location. However, you can typically expect to pay between £500 and £1,500 (ex VAT) for a single service.

Larger systems, plant rooms with multiple boilers, or those with complex controls and monitoring systems may cost more. Pricing excludes any replacement parts, which are quoted separately if required.

For businesses with multiple locations, servicing agreements or PPM (Planned Preventive Maintenance) contracts are often more cost-effective in the long term.

How Often Should an Industrial Boiler Be Serviced?

Industrial boilers must be serviced at least once a year, but six-monthly inspections are highly recommended for systems under constant load or critical use.

Regular servicing:

• Prevents unexpected breakdowns

• Ensures compliance with Gas Safety (Installation and Use) Regulations

• Maintains energy efficiency and emissions control

• Protects warranties and insurance cover

Remember: for gas systems, the engineer must be Gas Safe registered and qualified to work on commercial or industrial systems.

What’s Included in an Industrial Boiler Service?

A comprehensive industrial gas boiler service covers the full inspection and maintenance of your boiler and connected system, ensuring it’s operating safely and efficiently.

Typical tasks include:

• Full burner inspection and testing

• Cleaning heat exchangers and combustion chambers

• Gas tightness testing

• Checking flue and ventilation integrity

• Water quality and inhibitor testing (for sealed systems)

• Safety valve and control checks

• Flue gas analysis and combustion efficiency testing

• Electrical and control system inspection

• Issuing of service documentation and gas safety records

Depending on your site’s needs, additional plant room checks or pressure system inspections may be included.

Signs Your Industrial Boiler Needs Immediate Attention

Don’t wait for your scheduled service if you notice:

• Fluctuating temperatures or poor heat delivery

• Leaks or pressure drops

• Black smoke or yellow burner flames

• Unusual noises or smells

• Frequent lockouts or system faults

These symptoms can indicate serious faults, such as burner failure, heat exchanger cracks, or control issues, which can be dangerous and costly if ignored.

Benefits of Regular Industrial Boiler Servicing

Routine servicing is a smart business decision with measurable benefits:

• Keeps systems running efficiently

• Avoids unexpected downtime

• Reduces fuel consumption and carbon footprint

• Extends system lifespan

• Ensures compliance with safety regulations

• Maintains insurance and warranty cover

Regular boiler servicing is essential in an industrial setting for safety, productivity, and peace of mind.
