Hi
I've had a single storey extension built with underfloor heating (about 35m2)
The plumber assured me that the UFH would have it's own "zone", but from my understanding of reading about Y-plan, S-plan etc this isn't the case based on the design of my system.
Previously I had a Y-plan (sealed) system which fed either the radiators or the hot water cylinder.
When the underfloor part was added a new 2-port valve was installed on the feed from the boiler as per the image below:
Do I need another 2-port value before the 3-port?
Or should it be converted to an S-plan? If so, does that 'just' mean adding 2x 2-port values for the radiators/cylinder in place of the 3-port valve?
I'm going to speak to the plumber, just rather have some basic knowledge before I do!
Thanks
