Hi all
I am undertaking a major renovation of our home and planning to install wet UFH to all of downstairs.
Size is 50sqm with a recent extension adding approximately 15sqm on top of this.
My two choices are currently either an overlay system (18mm panels with 12mm pipe) from the likes of PolyPipe or to mill / channel out the existing concrete floor screed.
The advantage of the milling option is no additional floor height but the disadvantage seems to be zero insulation as the original solid floor has no insulation below.
I was recommended JK Underfloor heating which are a national company. Price wise, they are approximately £3k to mill out, lay the pipes (14mm) and fit a manifold. (This would then need to be connected by the heating engineer).
Does having 18mm of insulation (panels) on the floor provide any significant benefit? (Compared with simply inserting pipe into the existing screed)
Has anyone else decided between these two options?
In addition, I have been advised that my combi boiler can be used (with zone valves) but does anyone know if I need an extra pump at the UFH manifold (even though the combi is already pumped)?
