Where to buy ASHP manifold/pump/pipework

[Happy Valley]

Looking for recommendations please for better manufacturers/suppliers of manifolds - need two: a 7 zone and a 9 zone

 

Also who is best for MLCP pipework - need about 1300m

 

I may have a go at this myself when the time comes later this year.

I bought mine from Wunda and got good service/advice.

16 zones seems a lot - how have you worked that out ..?

 

And another for WundaTrade - manifolds and pumps are top notch, pipe is all much of a muchness. 
 

if you’re doing it yourself then buy the auto balancing actuators and save the grief of trying to sort it.

Thanks - the two manifolds were recommended by a well know supplier (not Wunda Trade). I thought it a little odd as we are only 160 sq m or about 130 sq m of required area for heating over two floors.

 

Also been recommended 150mm gaps using an 8.5kw ASHP. I can understand this particularly near large sliding doors where it will be slightly cooler. We have fairly good on U values  with a 180mm warm roof, ICF and stone/block work and a 250mm raft with 200mm of insulation above.
