Solar Thermal Hot Water Service

 

Solar Hot Water ServiceKeeping your Solar Thermal Hot Water System well serviced is a vital key to maintaining good efficiency of your system and maximising your investment. Neglecting your system from servicing will hinder your financial return and potentially lead to failing parts and costly repairs.

 

  • Solar thermal heating systems are relatively low maintenance systems unlike a boiler or car and do need as frequent servicing although should not be neglected from a clean and visual check every 18 months. The only moving part is the pump which is a relatively low cost item. The electronic controllers sometimes fail and these are also reasonably inexpensive.
  • Keep an eye on your system. The main thing to watch out for is fluid leaks – especially the antifreeze which smells rather strong. If there is a leak contact a service engineer.
  • Make sure your solar  thermal system is doing what you expect. If the weather is sunny and your hot water cylinder is cold you may wish to look a bit deeper – unless of course you have just enjoyed a deep, relaxing bath!
  • Similarly if the pump is running but the solar pipework is cold you may have an airlock which your service engineer can sort out for you.
  • One thing you may wish to look at from time to time (say once a month) is the pressure of the system which should between 1 and 2 bar – although it can drop as low as 0.5 bar in cold weather as the fluid contracts and as high as 3 or 4 bar if the system gets very hot. This is nothing to worry about but if the system falls below 0.5 or above 5 bar and stays there, contact a service engineer.
  • The antifreeze in your system will degrade over time and need replacing on average every 3 years. However bear in mind that the antifreeze is designed to cope with temperatures as low as -28C; the coldest temperature ever recorded in the UK is -27C and that was before climate change. So the system should be fine for at least 3 years.
  • If you want peace of mind, service engineers like us will perform a clean and visual health check every 18 months and a full service every 3 years to check everything is working as it should and your system is generating maximum hot water to give you the best return possible from your investment.
  • Something that is overlooked is keeping the collectors clean from dust particles, moss, debris and general dirt. A regular clean can improve the efficiency of your collectors by up to 20%.

If you have any questions about your system or would like to book in a service and/or clean and visual health check please do not hesitate to call us.
