Commercial Heat Exchanger Service

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.
