Discuss Should UFH be nearly scalding at floor with Vinyl (LVT)? in the Water Underfloor Heating Installations area at PlumbersForums.net

Hi All.

I'm pretty sure the answer to the above is "no".

I've recently had UFH installed, with a mixture of porcelain (kitchen) and LVT (lounge). I have a mixture of neoStat wall stats but no floor probes. (I was never advised to get such). The UFH in lounge is sitting in Polypipe Boards and in scree in kitchen.

Now that we actually (post-heatwave) need the UFH, we've noticed that the LVT is "spongy" and almost too hot to stand on.

I assume this means the temperature is way too high? That, or there isn't enough substrate between pipes and LVT.

What's the best way to address this while ensuring performance (i.e. that it's still hot enough to warm the tiled areas). Should I ask the installer to reduce the temperature? Should I insist on lifting things up and fitting floor probes (which sounds painful)?

Many thanks in advance.
