Vaillant system set-up help

[James89]

Hello, I’m hoping someone can help as I’m getting differing advice every time I speak to Vaillant;

We are refurbishing a property and installing a Vaillant Ecotec Plus 630 system boiler with a Megaflo cylinder.

We are creating 4-zones:
Downstairs rads
Upstairs rads
Bathroom underfloor heating
Bathroom towel rails

The plan is to use SensoComfort with SensoNet VR922 Net Gateway to have weather compensation and use via the app.

The downstairs and upstairs rads are to be individually controlled via 2x SensoComfort wired panels.

Vaillant advise that SensoComfort and electric thermostats can’t be used for the towel rail or underfloor heating zones due to being a damp/wet environment. Instead they have suggested simply using VR70 and a VR71 wiring centre to add the zones without thermostats/temperature control.

All the rads could have manual TRV’s, and the towel rails could have TRV’s.

They also advise that with this setup future upgrades to smart Ambisense TRV’s would require ALL rads on a zone to have the smart TRV’s, and they can’t be individually upgraded.

Is anyone able to help with designing this system setup in the best/most cost effective way?

Thanks in advance

I would look at Evohome (or other similar systems) for system control. In my view Ambisense is expensive and no where near the capabilities / flexibility if the competition.

If you are considering Open Therm, moving away from Vaillant control systems will be a bigger challenge

Take a look at Viessmann boilers and controls they are far more flexible, Valliant make solid reliable boilers but have a tendency to make their controls over complicated . Kop
