vokera boiler compact 24 or 28?
if i turn off my vokera boiler completely,the pressure still seems to build up actuating the relief valve and venting hot water outside,why is this? the loop isnt attached,the flow control input off,is this a expansion vessel problem?heat exchanger?i had opend drain cock for central heating leaking water but kept pressure right,i also have a constant whistling from my bathroom tabs?can anyone help.when i close hot water tap pressure begins to rise again
