Hi, I have just updated my dhw circuit to include a 2 port motorised valve, a automatic bypass valve and a cylinder stat, previously my hot water was controlled by boiler water temp.
Whilst waiting for electrician to change wiring I had 2 port valve set to manual and all was ok, since getting wiring changed to s plan and swtching the 2 port valve to auto I have noticed a bubbling type of noise when I have the dhw switched on, if I turn on the central heating the other 2 port valve opens and noise fades away,does anyone have any suggestions ?
Thanks in advance
