Ground Source Maintenance

After a good installation of your ground source heat pump there is very little if any maintenance needed. There is often a yearly visit necessary to keep the guarantee valid and various manufacturers have yearly checks that they require a record of.


  • Glycol check - this is carried out with a refractometer and gives a reading of the percentage of antifreeze in the system.
  • Field settings - Run through field settings to check they are all as per manufacturer’s instructions
  • Strainer cleaning - often there will be a strainer on Ground Source Heat Pumps to prevent dirt entering the machine, this dirt collects in a strainer and can affect flow rates of the heat pump, it is a good idea to clean this out once or twice a year.
  • Clean the coil 
  • Immersion - check current and if it is still performing the legionella cycle.
