Awards & recognition
Industry award finals and wins for our packaged plant rooms, recognised for the work we put in behind the scenes.
Why opt for a packaged or containerised plant room?
Space is usually what settles it. Fit the boiler, calorifiers, pumps and controls into a single steel enclosure and you free up ground floor or roof space that a conventional plant room would otherwise take up. On a tight site, that can be the difference between a scheme that works and one that doesn’t.

Made to measure plant rooms
While our PPR0007 and PPR0008 units cover most bases, Adveco also designs and manufactures bespoke packaged plant rooms for large-scale or specialised projects. Our qualified MEP designers oversee the process from beginning to end — one point of accountability, no need to manage multiple contractors.
Plant rooms can be configured with:
- ASHP pre-heat coupled with electric or gas hot water boilers
- Solar thermal where roof space allows
- Gas boilers where the site is on mains supply
- Hybrid ASHP/electric systems designed not to exceed the building’s EV supply capacity
- Stainless steel or carbon steel storage vessels dependent on water type
- Any additional controls or BMS interfacing required
Packaged plant rooms for hot water systems:
the PPR range Adveco has a range of standard packaged plant rooms designed to house our pre-engineered electric hot water systems built around FUSION hybrid water heating technology.
Packaged plant room with electric hot water: PPR0007
The PPR0007 is a compact unit shipping with a 24kW Ardent electric boiler feeding a 210 litre stainless steel ATSI hot water cylinder, plus a 9kW backup immersion heater. Ideal for hotels, restaurants, offices and schools.
Designed to be upgraded — start with a cost-effective all-electric system, then add an air source heat pump at a later date without replacing the entire plant room.

Packaged plant room with ASHP and electric hot water: PPR0008
PPR0008 adds a 10kW ADVS-W air source heat pump to the PPR0007 configuration, providing pre-heat for up to 70% of your DHW demand. This dramatically cuts carbon emissions and running costs.
Adveco calculated the PPR0008 can produce a 47% reduction in CO₂ emissions compared to a direct electric-only installation providing an equivalent annual quantity of hot water.

Whether a school campus is short on internal room or falls into the limited site access category, we can help meet term time deadlines with an offsite solution.
Reliability and built-in redundancy are key. Adveco can ship your packaged plant room directly to site for rapid installation by our team to meet critical demand.
Hotels have increasingly diversified, from providing high end dining experiences to swimming pools, spa and gym facilities. These functions significantly widen demands for heating and hot water.
High-recovery, reliable hot water that can be scaled based on demand. Our packaged electric or hybrid systems sit in a sleek GRP cabinet for new build or refurb.
Packaged plant rooms allow M&E contractors to separate their installation programme from works on site — taken care of independently, without site dependencies.
Perfectly suited to new build or older properties being converted into commercial spaces that simply lack room for a traditional plant room installation.
Frequently asked questions
Yes. Adveco’s large commercial electric boilers range from 60kW to 100kW and are designed with large commercial buildings in mind. By installing multiple electric boilers in your plant room you can achieve the total output you require while also building in redundancy: if one boiler fails, the others continue operating. These systems are used in hotels, hospitals and schools as both direct electric replacements for gas boilers and as backups to heat pumps.
How much you save by upgrading an old water heater to a new condensing model will depend on your existing equipment, current gas prices and how much hot water your installation uses on average. For larger commercial buildings running a water heater continuously, Adveco estimates savings of £220,000+ over the lifetime of the equipment when compared to a 25 year old non-condensing model.
Get in touch and we will assess your current water heater at no charge and give you an accurate estimate of your potential savings.
Strictly speaking, a commercial boiler is something that heats water and feeds it into a heating circuit. closed loop systems that use a boiler as their baseline heat source. A commercial electric water heater is more commonly used to refer to DHW production specifically.
As heating and hot water become more interlinked throughout UK buildings, the line between them blurs. Many commercial boilers can produce domestic hot water with the right controls, and that includes Adveco’s ARDENT electric boiler.
