Hi all,
I have just moved into a four bed 1960s detached house and the heating is at the end of its life. I am planning to replace everything with a system boiler and an unvented hot water cylinder.
For the ground floor, I am torn between radiators and wet UFH. The floor is an existing concrete slab and I assume it has no insulation. I do not want to dig it up.
The finished floor will be a mix of LVT, engineered wood and tiles. I am looking at low profile overlay UFH systems with a thin insulation layer, for example Nuheat LowPro or Omni, that claim they can be fitted directly over the slab, I have a ceiling height of 2.43m.
Has anyone fitted insulated overlay UFH over an uninsulated slab with a gas boiler, and was it actually efficient in practice, or did you end up wishing you had gone with radiators instead?
Many Thanks, Ben
