Many thanks!Yes leave at those settings you mentioned above. Note if the rads struggle to get to temperature during extreme weather you may need to increase the flow temperature knob a bit but all these things should be considered during design stage. I’m not a fan of Worcester boilers personally but your system is installed now.
Most of us engineers on here are happy to help if possible. Myself and John here are passionate about what we do and if we can help and educate a little we will.
Really appreciate your input and John's!
As said, I know more from you guys online then the so called gas engineer I paid thousands of pounds!
