Adveco supplies commercial gas condensing boilers and commercial heating systems for UK commercial properties. Our MD condensing boiler range includes floor-standing boilers from 70kW to 280kW and wall-mounted boilers from 14kW to 60kW. We also offer cascade installation options for larger buildings requiring up to 1.2MW total output.
The MD range is designed to provide reliable space heating and domestic hot water for offices, schools, leisure centres, hotels and industrial units. Both floor-standing and wall-mounted MD boilers feature stainless steel heat exchangers and condensing technology to deliver high efficiency, low total cost of ownership and significant operational savings over older non-condensing models.
As well as commercial boilers we also supply chilled water tanks for HVAC and cooling installations, and can design complete integrated heating and hot water systems combining gas boilers with renewable pre-heat from air source heat pumps or solar thermal.
Offering outputs from 70kW to 280kW, the MD floor-standing boiler range is suited to larger commercial installations. Designed for durability with stainless steel heat exchangers and condensing technology, MD floor-standing boilers provide space heating and domestic hot water with low operating costs.
Individual MD floor-standing boilers can be cascaded together to provide up to 1.2MW total output for very large installations. Because each boiler modulates up and down to match demand, cascade systems provide both scalability and built-in redundancy. If one boiler requires servicing, the remaining boilers carry the load while maintenance is carried out.
Suitable for new builds and retrofit installations where gas boilers are permitted by planning regulations. Available in 70kW, 100kW, 150kW and 280kW outputs.
Compact and straightforward to install, our MD wall-mounted condensing boilers are available from 14kW to 60kW in a space-saving format ideal for plant rooms where floor-standing boilers will not fit. Like the floor-standing models, wall-mounted boilers can be cascaded to provide total output greater than a single floor-standing boiler while retaining full service access to every unit.
Wall-mounted boilers are also well suited to new build or retrofit projects where the existing plant room cannot accommodate a floor-standing model. Adveco has supplied MD wall-mounted boilers for installations requiring over 60 units installed in three layers. Designed to the same specification as the floor-standing range, with stainless steel heat exchangers. Each unit is accessible for servicing by a single engineer with basic tools — no scaffolding or heavy lifting required.

Condensing boilers use a secondary heat exchanger to recover heat from flue gases that would otherwise be exhausted to the atmosphere. This process extracts more useful energy from each unit of fuel and can reduce both running costs and CO2 emissions considerably when replacing older non-condensing boilers.
Condensing boilers achieve efficiencies of 90% or above and, because they condense water vapour from the exhaust gases, can exceed 100% efficiency on a net calorific value basis. This means lower bills and lower emissions while providing the same heat output.
Installing an MD condensing boiler in place of an old non-condensing unit is one of the most straightforward ways to improve efficiency and reduce emissions for any gas-connected commercial building.
Installing multiple MD floor-standing boilers in cascade is the right solution for commercial buildings that need more than 280kW of heating output. Cascade design allows up to 1.2MW total output from the MD boiler range, with each boiler modulating up and down at part-load to match demand.
Cascade systems are also inherently redundant. Because output is spread across multiple boilers, if one boiler in the cascade arrangement requires maintenance or develops a fault, the remaining boilers can cover its output while repairs are carried out.
Adveco has installed cascade boiler systems across commercial premises throughout the UK. Contact our team to discuss whether cascade design is right for your heating system requirements.
Commercial boilers do not have to operate in isolation. Adveco routinely designs hybrid heating systems that use an MD condensing boiler alongside renewable pre-heat from an air source heat pump or solar thermal system.
Air source heat pumps and solar thermal provide lower cost, lower carbon output to raise the temperature of your water or heating circuit flow. The MD boiler handles the top-up, providing capacity when the heat pump cannot keep up during peak demand or cold weather. This cuts gas consumption considerably while retaining gas for reliable performance in winter conditions and peak load periods.
For commercial buildings with net zero commitments, pairing a gas boiler with a heat pump can substantially cut Scope 1 emissions without requiring full system electrification.
Wall-mounted boilers require less floor space than floor-standing units. They are well suited to plant rooms with limited space or retrofit projects where installing a floor-standing boiler would require significant modifications. Wall-mounted boilers can also be installed in cascade to provide total output greater than a single floor-standing boiler while maintaining easy access for service and maintenance.
The MD range of wall-mounted boilers covers 14kW to 60kW per unit. By installing two or more MD boilers in cascade, total output can exceed that of a single floor-standing boiler while allowing each unit to be serviced independently.
Generally yes. Adveco’s MD floor-standing boilers start at 70kW and reach 280kW per boiler. Wall-mounted boilers range from 14kW to 60kW. If your building has high heating demands or large DHW requirements, a floor-standing unit provides more output from a single boiler, which can reduce mechanical complexity and allows for simpler pipework with fewer system connections.
Floor-standing boilers can also be cascaded to provide up to 1.2mW total output when required.
Our commercial LPG water heaters are well suited to off-grid installations such as rural buildings, farms and industrial sites, holiday parks and commercial buildings not connected to the mains gas network.
Condensing boilers extract heat from exhaust gases that would normally be vented to atmosphere through the flue. A secondary heat exchanger removes latent heat from those gases before they leave the building, increasing the total efficiency of the boiler.
Condensing boilers can exceed 90% efficiency and in ideal conditions return efficiency ratings above 100% on a net calorific value basis. More usable energy from the same amount of fuel means lower energy bills and a smaller carbon footprint. All Adveco MD boilers are condensing models with stainless steel heat exchangers designed for continuous commercial use.
Yes. Adveco’s MD boilers can handle both space heating and DHW production. When paired with commercial hot water cylinders, indirect calorifiers or buffer vessels from Adveco’s range, they can act as a single heat source for your building’s heating system and hot water needs. Get in touch to discuss integrating boilers with storage as part of a new installation or whole heating system replacement.

Yes. Adveco specialises in hybrid heating installations that combine MD boilers with air source heat pumps or solar thermal systems. Heat pumps and solar thermal raise water temperatures at a lower operating cost and carbon intensity, providing base load heating requirements while the boiler handles top-up capacity when needed. This substantially reduces gas consumption and allows businesses to cut heating emissions without giving up the on-demand capacity and cold-weather reliability of commercial gas boilers.
Our hybrid installation team has experience with complex installations combining heat pumps, solar thermal and commercial boilers. Call us to discuss your hybrid heating system options.
Yes. We offer ongoing servicing, maintenance and support for installed commercial heating systems via fixed-price contracts. Our boilers and wider heating system installations come with access to our UK-based support team for advice, planned maintenance and reactive servicing throughout the product’s life.
