Vokera Boiler Pressure Gauge

[accupro]

Recently when running the hot water the pressure gauge for the heating starts to wildly fluctuate back and forth accompanied by a strange noise from the boiler.

In addition it tends to loose complete pressure over 3 days. I have had the pipes checked out and there is nowhere that that amount of water is noticeable. Besides these two things the boiler its self seems to work fine.

Is this a problem and if so what might it be?

Expansion vessel fault or connection blocked.Release system pressure and check the exp vessel precharge.Model of boiler would help.

It is a Linea 735

If you havethe MI's you should be ok to check exp vessel pressures.You really need a foot pump with an accurats gauge.

I don't have the MIs and when Scottish Gas serviced the boiler recently I was told it was a pipe problem and nothing wrong with the boiler.

I think I will get them back out and save myself some time and effort.

Many thanks
