Hi Everyone,
I hope this is the right forum for this question, I have had underfloor heating fitted and I want to know what effect changing the pump speed would have on the system? Its just that in the manual it says the Grundfoss pump is normally set to position 3, well mine is at 2 and I want to understand why, or what would be the effect if I change it to pos 3?
All advice very welcome,
SDM197.
