Underfloor Heating and Radiators combined.

[Gray0689]

They work best when set up correctly with correct flow and return temps
So your going to possibly fit a heat pump in future what will you connect it into

Lower return temps for a condencing boiler, so larger rads = lower return temp

I dont think it is throwing money away, exept vogel & noot are v. expensive!

You could have weather comp temp. adjusted rads on one mixer and underfloor on another

who's sonic?

An underfloor heating system can tolerate a 50c flow. I think commercial systems can go up to 60c.
So if the radiators are sized for a 50c flow then where is the problem?
At the end of the day I could just turn the boiler stat down to 50c and let it run direct from that surely?

Why the need for separate mixers to the ufh?

 

[ecowarm]

There is no need at all Nordio
just size according to flow temp you require

So lol

 

[Gray0689]

There is no need at all Nordio

Yes there is a need
What happens if someone turns heat output up?
You will shock the floor possible cracking tiles etc

The boiler stat would make no difference, only if someone fiddled with the controller for the mixer valve. That can be protected in the installer menu

Most ufh systems have an overheat stat on the manifold to cater for mixer valve failures etc. So I can fit one of those.
Or as I've already mentioned the floor screed sensor.

Thanks.

You said there was no need for a mixing valve on underfloor!!!
