Fault Finding & Repair Service
Sometimes, regardless of the care you take, things can go wrong with your solar thermal system. In these situations you can get in touch with us knowing that, with our local offices in the South East and our wealth of experience and knowledge of solar thermal hot water systems we will be able to get to you quickly to locate the problem and resolve it so that your system is back up and running as swiftly as possible.
Common problems we deal with:
- Faulty pumps
- Control unit and sensors failing
- Air locks / blockages with the pipework
- Leaking components ( pipework, expansion vessels)
- Leaking hot water cylinders
- Storm damage
- Loss of pressure
- Panels being removed and reinstalled due to reroofing
We unfortunately cannot help with Thermodynamic systems
Health Check & Antifreeze Change
All solar hot water systems use antifreeze as it's heat exchange liquid to protect it from freezing in the colder months. This liquid degrades over time and should be changed every few years so we recommend a Full Health Check every four
years to review the system and check the quality of the liquid to ensure it is working as it should to protect your panels from low temperatures in the winter. During our 4 yearly assessment we will:
- Inspect the solar array for any damage or material failure (if access is available otherwise from ground level visual assessment)
- Inspect any visual pipework and insulation
- Check the performance of all system valves and controls
- Check the circulation of the system
- Test the quality of the anti-freeze liquid
- Drain down and dispose of old fluid where necessary
- Supply new anti-freeze and recommission where necessary
Taking care of your Solar Thermal System
It is important that you give your solar thermal system an occasional inspection yourself to check for any obvious issues,
and arrange regular check ups to ensure that your system continues to work at its maximum efficiency and getting
you the most out of your investment.
Keep Them Clean. The variability of The Great British Weather is such that dirt and dust are not likely to build up on your solar panels, making them pretty much self-cleaning, but it is worth keeping an eye just to make sure that there is no build up of grime that can reduce the effectiveness of the panels.
Look out for Over Hanging Trees. Keep an eye out for any infringing greenery that has sprouted up and may be overshadowing your roof and blocking the precious sunlight from your panels. (Make sure that you check with the necessary authority before you start lopping down trees!).
Cast an occasional eye over the system. Every now and again do a quick visual check to make sure there are no
obvious faults. That there are no leaks around the joints (antifreeze has a distinctive pungent smell), that the pressure is as it should be, the fan comes on when it is supposed to, there are no obvious cracks or damage etc.

Service and Repressurise Solar Thermal System. “I cannot fault the standard of service from this company. In my first telephone enquiry, all of the options were clearly explained and once I had made my decision I was contacted the following day to arrange an engineer visit. The engineer arrived on the day and at the time promised, and carried out the required work efficiently and professionally. He then explained the work he had carried out. I cannot recommend this company highly enough.”
