Hi

First post here and lurking for a while...…….

Just finalising plans for our kitchen and dining extension and looking at getting a wet UFH heating across the whole of the ground floor.

It is 1930s semi and it is a big area to cover and we are looking to put Karndean down as well....now I am getting a bit confused as to what and how the UFH should. I am 99% sure that the old part of the house has a suspended timber floor.

How would I go about having UFH across the whole ground floor and ensuring its level as well between old and new parts of the house? I have been looking at something called the JK UFH system and also Nu-Heat and Polypipe.

Also any issues with having the manifold in the garage as its cold in there.....this is where the boiler is and will be after the build.

Any helpers.....??

As Equus says.

I’m just about to do similar with existing suspended timber, existing solid and a new solid extension.

I called NuHeat and provided them with my plans they did all the calculations for me on what products I need across the different floor types and costs. It’s actually very simple when you get into it.
Thanks Gary - any idea what the height increase would be on the existing timber floor?

Also, just so I am not confuding things......I would need some insulation in between the joists, fit the flooring back?, install the UFH (nu-heat or similar), screed on top, plywood and then karndean flooring......is that correct???
