Repairs on systems not installed by First Call Solar
Many of the systems we are called to have been installed to quite low standards. This means that the parts used may be of low quality, and corners may have been cut in order to speed up the installation and commissioning process. The following remedial work is typically necessary in order to make a system more efficient.
- Carry out a visual inspection of the system, checking for leaks, faults and non-compliance with current standards of installation
- Reduced system pressure and leaks
- Check function of the solar controller and solar pump
- Drain the system and switch off the electrical supply
- Remove filling assemblies connect to fresh water supplies and cap both connectors
- Replace non solar expansion vessel and provide a quick-release coupling
- Remove any automatic air vents and cap connections
- Insert a new pressure relief valve in the return pipe work, and provide a container to catch excess solar fluid in the event of over pressurisation.
- Remove the collector mounted pressure relief valve, and cap the connection
- Flush the system with specialist chemicals to remove sludge and debris
- Fill and pressure the system with antifreeze rated to -40
- Switch on electrical supply, activate the solar controller and pump, adjust circulation
- Thermally insulate any exposed solar and hot water pipes
The work needed to return your solar thermal to good working order may be different. Please also note that we have experienced cases in which solar thermal systems were found to be beyond repair after an engineer had already spent a significant amount of time on fault finding. Unfortunately, we need to pass this on to our customers. Our standard service and repair charges will therefore apply.
Please feel free to contact with us by email or call 02380262690 to discuss any of your requirements.
