Top Tips

  • Solar fluid should be changed every 3 to 5 years otherwise the system will start to lose protection from the corrosion inhibitors. The fluid can become acidic causing pitting and pin holes and the antifreeze effectiveness is reduced.
  • Check the system pressure gauge every month. It shouldn’t drop below 0.5bar. This is the number one indication that there is a problem with your system.
  • At the end of March March, change the boiler hot water timing to just once per day (from 16:00 to 17:00) and on the next sunny day turn the boiler off to confirm that the solar system is actually heating the water.
