Our Range of Commercial Boiler Services

Commercial boilers are designed to provide heating and hot water for larger properties, including offices, schools, healthcare facilities, hotels and industrial premises.

Choosing the right system means more than choosing a commercial boiler. Factors such as building size, heating demand, fuel availability, efficiency and long-term operating costs all play an important role.

As approved Alpha, Navien and Viessmann installers, our highly-trained team of engineers provides expert guidance. From the initial consultation through to installation, we guide you through every stage of the process to help you find the best commercial heating system for your property.

Commercial Boilers For Heating & Hot Water

Commercial boilers require regular servicing and maintenance by suitably qualified engineers. Our Gas Safe registered engineers provide professional installation to ensure safe, efficient and compliant operation.

We also maintain accurate commissioning records and service documentation, helping support ongoing maintenance and compliance requirements. These documents are essential because commercial heating systems are subject to stricter safety and regulatory requirements than domestic installations.

Our installers ensure your commercial boiler systems comply with current UK gas safety and building regulations.

Boiler Types We Install

Our modern heating systems often include built-in safety features and intelligent controls to improve efficiency and system management. We install, repair and service a wide range of boiler types from leading brands. Where appropriate, we also recommend modular systems that allow heating capacity to grow alongside your business.

Regular Boilers

Regular commercial boilers are ideal for larger businesses with high heating and hot water demands, particularly buildings with existing heating infrastructure and multiple washrooms or kitchen facilities.

Working alongside separate hot water cylinders and storage tanks, they deliver a dependable supply of heating and hot water across larger sites.

System Boilers

System boilers are well-suited to commercial properties that require consistent hot water availability without a separate cold water tank. Every system boiler is sized and specified to match your building’s heating demand, delivering long-term durability and consistent performance.

Their simplified design can help reduce maintenance requirements throughout the boiler lifecycle while supporting medium to high-demand environments.

Combi Oil Boilers

Commercial combi oil boilers provide heating and hot water from a single unit, making them ideal for off-grid businesses with limited plant room space.

Every commercial building has different heating requirements, and the scale of your operation plays an important role in determining the right boiler capacity.

Factors such as occupancy levels, operating hours, peak demand and fuel type all influence the size and specifications of the heating system.

A professional heat loss and load assessment helps determine the right boiler output for your building and heating requirements. This ensures your system delivers reliable performance without unnecessary consumption.

Businesses with high hot water demand, such as hotels, leisure centres and healthcare facilities, should consider peak usage requirements during system design. Correct sizing helps avoid wasted energy, improves efficiency and ensures consistent heating performance.

Energy Efficient Heating Systems

Modern commercial boiler systems are designed to deliver reliable performance while helping businesses improve energy efficiency. Our modern boilers are manufactured with durable parts, including stainless steel heat exchangers, high-quality burners, and robust internal components, and are available in a variety of sizes and outputs. They help improve your building’s energy efficiency through:

  • Seasonal efficiencies of 90%: Helps businesses reduce energy consumption and running costs.
  • Condensing technology: Recovers heat that would otherwise be lost through the flue, improving overall system efficiency.
  • Smart controls: Advanced monitoring systems can help optimise performance and reduce unnecessary energy use.

FAQs on our Commercial Boiler Services

Here are some common questions about our commercial boilers. Read our guides for more helpful advice.

Different fuel types have different uses, and depending on your type of business, one may be better suited to your industry.

Fuel Type Uses Property Type
Gas Boilers Connected to the main gas supply and consistent heating demand. Widely used across offices, schools, commercial premises, hotels, restaurants, leisure centres, warehouses, apartment blocks, and care homes where mains gas is available.
Oil Boilers High heat output for large buildings where mains gas is unavailable. Rural hotels, country estates, industrial buildings, and agricultural facilities.
LPG Boilers Flexible heating solution for off-grid properties requiring cleaner combustion than oil. Rural offices, pubs, restaurants, holiday parks, small hotels, construction sites, community halls, and temporary accommodation.

Yes. Boilerhut is an approved installer for Alpha, Navien and Viessmann, and selected commercial boiler models may be available with extended warranties of up to 10 years, depending on the manufacturer, product range and installation requirements.

To maintain warranty cover, manufacturers typically require the boiler to be serviced annually by a certified engineer, with servicing completed in line with the manufacturer’s guidelines. Many warranties also require the heating system’s water quality to meet specified standards to help prevent corrosion and component damage. Keeping commissioning records and service documentation up to date is equally important for validating future warranty claims.

The primary differences between commercial and residential boilers lie in capacity and complexity. Commercial boilers are designed to heat larger buildings with higher, continuous demand, while domestic boilers are built for the lower heating and hot water requirements of single-family homes.

Feature Commercial Boilers Domestic Boilers
Typical output Usually 70 kW+ (can exceed 1,500 kW) Typically below 70 kW
Application Offices, schools, hospitals, hotels, warehouses and industrial buildings Individual homes and small residential properties
Operating demand Built for continuous, heavy-duty operation, often 24/7 Designed for intermittent daily use
System complexity Often modular or cascading systems with advanced controls Single boiler serving one property
Energy efficiency Modern condensing models achieve 90%+ efficiency, with some wall-mounted models reaching up to 98% gross efficiency High-efficiency condensing technology is common but designed for lower demand
Sizing Selected using a professional heat-load assessment based on building demand Sized according to household heating and hot water requirements
Maintenance Annual servicing by certified engineers, maintenance records and water quality management are often required Annual servicing recommended with less complex maintenance requirements
Compliance Subject to stricter commercial safety regulations and environmental standards Must comply with domestic gas safety regulations
Reliability features May include modular redundancy, smart controls and high turndown ratios Simpler systems with fewer redundancy features
