Hi,
I've recently had an extension built and with it underfloor heating installed. This has been installed in its own zone and the existing rads have been zoned off too.
The problem is that since this has been done the rads are not as balanced as they used to be so I've been working on rebalancing just the rads (with UFH off) but the by-pass seems to be triggering even though every rad is fully open.
The actual return pipe from the rads is cold'ish but the other side of what looks like a bypass valve is hot. It seems the boiler is looping around the bypass value rather than pushing the heat to the rads.
I think the bypass value, which looks like a tap without a head, is a bypass valve but can't find any images on the net to convince me!
EDIT > Actually - it looks like a gate valve like item 63209 on www.screwfix.com.
Interestingly my boiler has an auto bypass so perhaps I can just take it out?
Any ideas?
Thanks,
Dan
