Maintenance

Provided some simple maintenance is carried out, the expected life of a solar water heating system is in excess of 20 years and we have seen many examples to prove this.

Annual inspection (usually by owner)

Externally
Observed from ground (perhaps using binoculars)

  • that the glazing seals are weathertight and sound
  • that all insulation is firmly attached
  • that there is no evidence of serious corrosion or persistant condensation
  • that all covers, fixing screws etc are in place and the panel is secure
  • that any anti-bird wires are in place (if fitted)
  • that the panel sensor is secure in the pocket provided
  • that the automatic air vent (may be in loft) shows no leaks

Internally

  • that all air has been expelled from the system (none observed in flow-meter window or audible in pump)
  • that all insulation is firmly in place
  • that there is no damage to pipework
  • that there is no evidence of leaks
  • that the system is at the correct pressure (for sealed systems min 1 bar)
  • that electrical controls and operational indicators are working correctly (see separate DTC manual)
  • that the sensors are securely fixed and that all covers, fixing screws etc are present
  • that the pressure relief valve releases fluid when briefly twisted and shuts off after

A competent person should deal with any points arising from the above.

Five-yearly checks

  • The system should be completely drained and flushed, then refilled with new antifreeze/inhibitor.
  • Check all insulation, pipe work and correct operation of components.
