Mechanical Tasks - Maintenance tasks - Unit / water and heating system

  • Check with the water supply turned off and the hot water taps open, check the expansion vessel charge pressure and top up as necessary

  • Check with the water supply turned on, open the temperature relief valve and then the expansion valve to check the unrestricted discharge into the tundish?

  • Check valves for freedom of movement and confirm that the water stops and both valves reseat correctly. Check at a full bore discharge from either valve that there is no back up or discharges over the tundish

  • Check that the correct outlet pressure is being maintained by the pressure reducing valve by recording the pressure at the terminal fitting or the tapping provided on the combination inlet valve.

  • Clean flow regulators (or restrictor/aerators) on each terminal fitting tap/shower as applicable. Check for correct flow rate at terminal fittings

  • If necessary descale the heat exchangers immersion/heaters in hard water areas

  • Check and clean the Boiler Buddy

  • Open the primary/heating system safety valve and check that it discharges safely

  • Drop the primary/heating system pressure to zero - check and if necessary top up the air side of the expansion vessel (1.5bar)

  • Check and if necessary top up the concentration of the heating system Inhibitor (Alphi 11 - 25% minimum)

  • Re-establish the primary/heating system pressure (1.5bar) and disconnect the filling loop

  • Check the primary/heating system pressure does not rise above 2.5 bar and the safety valve does not drip when the system is at full

  • Check and release any air from the primary/heating systems

Electrical Tasks / Checks:

  • Visually Inspect, checking for the presence of supplementary bonding and that it is being maintained

  • Check correct rating and type of fuse is fitted on the electrical supply

  • Check for the correct operation and temperature setting of the thermostats

  • Check the operation of the motorised valves

MAINTENANCE TASKS - OUTDOOR UNIT:

  • Visually for signs of oil leaks which may indicate a refrigerant leak (check for leaks if necessary)

  • Check integrity of water pipe work and lagging

  • Check all electrical connections including mains isolator

  • Check unit operation voltage and record

  • Remedial Work Required:

CYCLICAL SERVICE - DOMESTIC UNVENTED HOT WATER STORAGE VESSEL INSPECTION CHECKS:

  • Operating Temperature and Temperature Relief Valve or Operating temperature and pressure of combined temperature and pressure relief valve (Indirect heating vessel): (bar/C)

  • Discharge Pipework (D1) - Relief Valve to Tundish:

  • Check Length of D1

  • Is the tundish installed within the same location as the hot water storage vessel?

  • Is the tundish visible?

  • Is automatic means of identifying discharge installed?

Discharge Pipework (D2) - tundish to point of termination

  • Normal size of D2: (mm or Inches)

  • Pipework material: (Copper / Steel / Plastic)

  • Does pipework have a minimum vertical length of 300mm from tundish?

  • Does the pipework fall continuously to the point of termination?

  • Method of termination?

  • Method of termination satisfactory?
