Hi all,
I'd like to install an automatic bypass valve on my central heating system. It's a pressurised system using a Worcester Greenstar 27 CDI combi boiler. I have a few questions:
1) Apart from the obvious (that it should be between the feed and return pipes of the CH) are there any recommendations (i.e. minimum distance from the boiler etc.) where to position it?
2) Does anyone know the minimum flow requirement of my boiler? I managed to find the characteristics of the built in pump, but I'm still missing this information. That'd help me figure out the pressure setting of the bypass valve.
3) Any suggestions which bypass valve to use? Their prices vary wildly between £8.35 (Zilmet from JTM) and £46 (Honeywell from Screwfix)?
Thanks in advance.
