This service covers planned maintenance, fault diagnosis and repair for plate and shell heat exchangers, helping reduce energy waste, protect equipment and minimise disruption to your building. ## What commercial heat exchanger servicing covers A heat exchanger sits at the heart of many commercial heating and hot water systems. Regular servicing helps maintain heat transfer, stable temperatures and safe operation. - Inspection of plate or shell heat exchangers for leaks, fouling and wear - Performance checks (temperature drop, flow rates and pressure readings where accessible) - Cleaning solutions to remove scale, sludge and debris, with advice on preventing repeat fouling - Replacement of consumables where required (for example gaskets and seals on plate units) - Fault finding and repair to address poor output, noise, blockages or pressure issues - Commissioning and recommissioning after repairs or system changes - Service reporting for site records and planned maintenance schedules ### When this service is most useful This service is a good fit if you manage an office, retail unit or managed property with a central plant room and need dependable heating and hot water. Typical triggers include: - Higher energy use with no clear change in demand - Slow warm up times, unstable temperatures or poor heat output - Rising differential pressure, frequent pump issues or repeated call-outs - Evidence of contamination in the system (sludge, scale or discoloured water) - Compliance and audit requirements that need clear service records ### How the service is delivered Work is usually carried out as part of a planned preventative maintenance visit or as a targeted repair. - Site assessment to confirm exchanger type, access, isolation points and system condition - Safe isolation and controlled drain down where required - Strip down and clean for plate exchangers, or in-place cleaning where appropriate for shell units - Reassembly, pressure checks and functional testing - Recommendations to improve reliability, such as filtration upgrades or water treatment actions ### After the visit: reporting and ongoing value You receive clear findings and next steps, so you can plan budget and avoid repeat downtime. Where needed, ongoing PPM scheduling can be put in place to track condition, reduce unexpected failures and keep performance stable across the year.

Most sites service heat exchangers annually as part of a PPM schedule, but higher-use systems may need more frequent attention. Frequency depends on water quality, load and any history of fouling or blockages. Will the system need to be shut down during servicing? Some tasks can be done with limited disruption, but internal cleaning usually requires isolation and a controlled shut down. If continuity is critical, the work can often be planned out of hours or coordinated with other maintenance. Do you service both plate and shell heat exchangers? Yes, the service covers both plate and shell units commonly used in commercial heating and hot water systems. The cleaning method and access requirements vary, so the approach is confirmed on site. What are the signs a heat exchanger needs attention? Common signs include reduced heat output, slow warm up, unstable temperatures and higher energy consumption. You may also see higher pressure readings, pump strain, or evidence of leaks and corrosion. Do you provide documentation for compliance and site records? Yes, you receive a written service record outlining what was checked, what was found and any actions taken. Where repairs or further works are recommended, these are listed clearly for maintenance planning.
