potterton lynx 2 boiler problems

[Tlcon]

Hi I am new to this but am desperate
I have an old potterton lynx 2 combi boiler that firstly is losing pressure daily around 0.3 bar also the hot water lasts around 30 secs before going cold heating when pressure is up works fine

Please help

U need to find out why its losing pressure - is the prv leaking ?

pressure release valve if this is drained to outside then I think so not loads though

Get the prv sorted then - you are going to get continual probs if you don't

This is probably happening because the expansion vessel is flat as well. Any decent engineer will know how to fix that.
