OpenTherm with Multiple nests on underfloor heating

[picasso]

Using opentherm ?

 

[Dan Robinson]

Mine works great with UFH radiators and an unvented cylinder. But what would I know. I'm only a manufacturers part swapper.

Mine too with Evohome and Opentherm on 6 zones.... Mixed UFH and rads


Well until I put my Intergas in anyway

Ok then, is there a specific UFH controller that can modulate right down to 40-50 degs flow when the only call for heat but still have intelligence to override the flow temp when there is a call for heat for DHW when required?

 

[Dan Robinson]

Evohome.

For the second time

OP, what is your boiler make and model?

 

[Nick Slatter]

Ideal logic heat 18

Evohome is too expensive. Nest has more technology for less. £939 v £600 for a 3 zone set-up.

I'll live with no opentherm and have a much better UI and slicker app.

 

[Dan Robinson]

Evohome is too expensive.

Because it does what you want. I bet you own an Apple/iPhone.

More concerned with what stuff look slike than how it works. What you don't realise is that you shouldn't be monkeying around with the settings anyway. It matters not a schit how slick the app is because you should only be interacting with it when you go away on holiday.

And it isn't £900 for a 3 zone system if you're comparing like for like technology.

I just think that if you are going to put something on your wall and integrate it as part of the building then appearance is a factor.

Regardless of this fact, the Nest still has more advanced tech than the others. Geofencing for example is not as good as local presence detection, especially when there is more than one person in the household.

Only if you don't know how heating systems and compensated controls work.

Using opentherm ?

Yes

I never feel the need to "once in a blue moon" feck about with my heating settings using my phone
It's tech for tech sake.
My house and heating system was built to my spec and it just works.
I might be doing it wrong or something

 

[Nick Slatter]

So what system do you have?

I hope you mean it works well rather than 'only' just works sham.

That is what the set up is at son's place.
