What do we do on a unvented cylinder service?

Whats involved in an unvented cylinder service?

The most important thing for us is checking the system is safe to use.

On a unvented cylinder service we carry out the following:

  • Strip out line strainer and clean - this stop any incoming debris coming into your system.
  • We checks for any signs of leaks - crusting around pipework shows previous leaks.
  • check and top up pressures in the expansion vessels / internal air gap (A very important part) -if you don't have the system serviced annually, this is the main reason for faults to happen on unvented cylinders.
  • check safety relief valves operating safely.
  • checking for installation errors (Happens all to often).
  • check hot water temperature corresponds to dual stat.
  • top up pressure on heating side (if applicable). 
  • check flow rates.
  • make sure electrics are safe and working correctly.
  • fill in the service log book.
If your hot water cylinder isn't serviced annually then you could actually be damaging the system and cause potential issues with the system.
