UFH different floors.

[Screech20]

Hey guys!

I’m in the early stages of planning my rear extension and would like some advice on the wet underfloor heating.

The existing floors are suspended timber, and the extension will be solid.

I will be knocking the kitchen into the extension so would like to run UFH in both old and new.

I have read that it’s not advised to do this as they both need to run at different temperatures.

Is there a system that will allow for this or would it be a case of running 2 separate systems/manifolds?


Thanks!

My ground for is open plan living room and kitchen with one large zone of ufh. It works fine and is an overlay system.

And yes, it is a mix of original and extension.

Thanks, sounds promising.

I’ve researched and they’re so many different way of doing it.

It seems the best/most effective way is to screws over the timber floors.

Insulation between the joists, heating pies, screws over level with tops of joists, re-board, then floor covering...
