Hi,
Hoping someone can help.
Have recently moved into new house with a glowworm Ultracom 18Hxi boiler/
Issue I have is the hot water is not getting to temperature of 60C set on cylinder stat - the cylinder stat is new, I measured the tank temperature with a temp probe on my multimeter and it reads around 50C and if I move the stat to 50C the boiler and pump turn off as expected.
So, with just the HW turned on at the timer the pump runs continuously for hours as I guess the HW stat is constantly calling for heat, but tank never gets to 60C...
The boiler is set to 75C, I notice when it fires up it only burns for say 30 seconds, quickly hits 75C on the display and turns off however measuring the inlet and outlet pipe temps it doesn't seem to be 75C.
If I turn the CH on as well at same time the boiler burns for much longer and the temp display on it climbs much slower.
Any ideas? Is this a boiler issue?
The system has been powerflushed as well and its had a new 3 way valve as that wasn't working correctly either. Tried pump (also new) set on 1 and 2 same issue.
Thanks!
