In the process of trying to have a ASHP installed after complete refurbishment (actually ended up demolishing most of my 1920's house). I've installed UFH throughout and plan was to maximise efficiency by using the low temp features of a Heat Pump. I have an preferred MCS installer but been having a few debates on the installation.
Points of debate are:
1. do I need a mixing valves for a low temp UFH design ?
2. should there be pumps on each of the (three) manifolds or only one pump for all manifolds?
3. and linked to question 2 above - Is a buffer tank the best/simplest option ?
Any other thoughts, suggestion, advice (see graphic) would be greatly appreciated and thanks for reading this.
Cheers Ash
