Underfloor heating installation advice

[andys26]

Hi all first time posting here and I apologise if this has already been covered but I am looking for some advice on an underfloor heating system.
It's a 3 zone wet ufh system with Heatmiser (UH4) wiring centre and 3 heatmiser WiFi hardwired Neostats
The wiring centre is installed with power to it but nothing else wired up to it. The sparky doesn't usually do UFH systems so has given me the details of someone who will. I have spoken to the guy and he's not free for another 4 weeks and it's pretty dam cold in the house ATM . Just wondering if this is something I can do but have a few questions before I dive in.
We have a Worcester Green star Heatslave 2 combi-boiler controlled by a Hive system I wired in last year. This controls the radiators upstairs which all have Hive TRVs on, so I can control them all individually. It also controls the hot water system too
First question is will one port valve on the flow to the UFH system be sufficient for this setup? The UFH system has been installed where an old radiator used to be, if that makes any difference
Second question
When I run the boiler enable to the boiler from the UFH is it best to just wire this into the switched live that the Hive also uses, or would it be better to wire the Hive system directly into the wiring centre and wire the wiring centre directly into the boiler?

Has it been connected to the pipework before or after the radiator zone valve? If it's after then it'll only ever work when the radiators are on. I'd suggest you probably want to ditch the Heatmiser stats and go with Hive to control it otherwise you have two systems potentially fighting each other.

I haven't actually installed the Port valve yet so I can put it wherever it needs to go potentially.
Can you setup Hive to control different zones in the UFH system?
If I wanted to use the Heatmiser stats I'm guessing I would have to install two zone valves?
Not sure I can return the stats now so would like to use them if I can

Not sure if it's worth mentioning too but I've got electric actuators also on each individual zone on the UFH manifold

If you have two zone valves you can run the systems independently, (need two thermostats) I find this useful this time of year I leave my floor on 24/7 (low) the house rads programmed to come on and off as needed.

Awesome ok that makes sense to me. I think that may be the best route to make things simple

Also just a thought but if I have electric actuators on each zone with an individual thermostat for each zone/room. Would I need a two port valve on the flow pipe into the UFH system or would the electric actuators effectively be like independent valves on each zone on the manifold?
Just wondering if it's overkill to have a two port valve and electric actuators all together?

Beyond my knowledge, best wait for the plumbers to come along to advise more.
