I changed the c/h thermister like you suggested, I checked burner pressure and it read 11mb, i thought it had cracked it but then realised that all settings were set to maximum, I changed the thermisters back, and still the burner pressure is 11mb. This means there has been a 3mb rise from the...

bump, any other suggestions im going back tomorrow

hi, £60 labour plus the head exchanger? if it included the head exchanger that sounds to cheat to be true. If it was the plate to plate head exchanger it could have been cleaned which would save a lot of money

a boiler needs to be fastened to a non combustible surface

has no modureg only 1 wiring harness with 4 wires ,like a multiplug

20mb

pcb checked and potentiometers have all been adjusted to max but will not achieve more than 8mb

if flow rate reduced we get hot water upto 60 degrees -so plate never considered as this was getting hot fine and maintaining its heat but burner pressure is just same when doing heating

yes voltage is as manufacturers instruction,according to manual if burner pressure cannot be achieved by potentiometer then can be adjusted on gas valve,on both parts burner pressure can be adjusted down but not up,no more than 8mb........with new gas valve not even allowing any gas through i...

no modulation is done through p.c.b

inlet pressure is 21mbar, working presure is 20mbar

yes definatley mid pos. valve ,possibly got some sediment on the flap that closes the heating port and allowing it to bypass. i am of course assuming that this has never done this in previous years when turning heating off and only runing hot water as this could be a design fault with the...

Glow worm compact 75e combination boiler. problem: the water is only just getting warm at every hot tap and shower unit, too cold to get a shower. flow rate reduced and hot water gets hot. burner pressure checked, 8mb burner pressure should be 14.7mb Solution: increase burner...

Vailliants are very good boilers, probably better than vokera in my opinion but vokera are still a very good boiler. we tend to still to fitting just vokera so we can stock quite a few parts for breakdowns. :) good luck choosing

we fit a lot of vokera boilers because we havn't had any problems with them and parts are reasonably priced, customer service isnt bad either.
