Some radiators don't work at all. Boiler sometimes depressurises. Looking for a highly experienced heating engineer who can try to get the system working more efficiently.

Installation of a hard-wired Hive thermostat to replace a manual thermostat that was installed with my Worcester combo-boiler. The boiler is a Worcester Bosch 8000 system and only installed 18 months ago - so should be compatible with the Hive thermostat. I’ve bought a Hive bundle that include the hub to allow set up of the WiFi-enabled remote control. I’ve included pictures of the boiler system, current thermostat unit and Hive pack. Happy to provide any extra information required to quote:

Urgent Central Heating Diagnostics & Balancing (Fixed Price Required) ​We seek a patient, Gas Safe Registered heating engineer for a fixed-price assessment (not hourly) of our older, closed-system central heating. We need a definitive solution to severe heat distribution issues. ​📝 Problem Summary ​Boiler: Older Potterton condensing, external in an outhouse, with pipes running underground. Hot water supply is fine. ​Heat Distribution: Ground floor is hot (adequate). First floor is very cold/uneven. One upstairs radiator is piping hot, but all others are cold/lukewarm. ​Pump Issue: The external Grundfos pump was recently replaced with a generic unit that may be inadequately sized/configured for the long pipe run. ​Critical Radiator: The mezzanine radiator is key—when it works, the first floor warms up; when it's off, the first floor is cold. ​🎯 Required Assessment ​We need a thorough diagnostic, not a quick check: ​Pump/Flow Assessment: Verify the replacement pump's sizing, head, and flow rate are correct for the system. ​System Balancing: Fully diagnose flow issues and professionally perform a lockshield and TRV balancing procedure, prioritizing the 7 first-floor radiators and the critical mezzanine unit. Advise on necessary TRV replacements. ​Blockage Diagnosis: Inspect for and advise on blockages/sludge; propose the remedy (e.g., Powerflush or chemical clean). ​We are looking for a detailed, fixed-price quote for the diagnosis/balancing, and a clear proposal for all necessary remedial work (e.g., pump, Powerflush). ​🙏 Personal Appeal: We have an autistic, non-verbal son whose room is cold. Finding a patient, experienced problem-solver to restore reliable warmth is deeply important to us. ​Please confirm Gas Safe registration, experience with older, complex systems, and state your fixed price for the on-site diagnostic and assessment.
