Am looking to keep my higher temp water in/near to the thermal store. So I'm thinking of having an ufh pump and mixing valve in the boiler room.

I presume I will need 2pumps?

Will it work to then run in 22pipe to my ufh manifolds?

How would this affect wiring?

Are motorised 2port valves needed? Is so where?

Thanks]]> Ufh.

22 pipe may be a bit small depending on the flow rates you need, your UFH design should state the required flow rates. From these you can also work out the size of the pump you need.]]>
