Bad Wet Underfloor Install - Help Needed

[DIY_Webby]

Help please. I've had wet underfloor in my new extension put in by a builder and plumber who (unbelievable) don't know anything about it and have asked me what to do. Don't worry they won't be getting near it again. I have two zones (1 pipe for one zone and 2 pipes for the other zone) that have are connected to a mainfold which have flow controls and electric actuators. The pump and actuators are connected to a Hive multi zone which go to a gas boiler (not combi).

My concern and help is needed that there is no mixer or pressure values. The mixer is a concern as the full heat of the hot water that goes to radiators and hot water will go underfloor (not efficient at current gas prices). secondly do I really need pressure values?

Can I just add a mixer and what's recommend for this set up?

Many thanks

which boiler do you have some can control this, but not many, you will probably need a blending valve

I hope the electrics is intended to be temporary…or couldn’t they afford clips either…

Is that actually UFH pipe or just some kind of speedfit pipe?
