Completely clueless underfloor heating

[Abbiel123]

I live in a property where underfloor heating was already installed by a previous owner. No manual was left, not even sure of the model/setup of our system (other than the fact that it’s a wet system linked to my boiler/central heating system & I can see these pipes behind a cupboard). It is definitely over 6 years old as the owner I purchased from said it was already here when she purchased, possibly a lot older??

Looking at this photo I believe it is a Unipipe system?

The heating is installed in 3 downstairs rooms/zones, it seems to work in the kitchen & bathroom but not in the living room & I’m not sure if I have to turn anything or bleed anything or if I just need to get a plumber to come in & take a look!!

Completely clueless!!

Have you got a thermostat on the wall in each of the zone / rooms?
Are they battery powered and are the batteries good?

Thanks for your comment.

Just the one digital thermostat linked to the central heating boiler.

All upstairs radiators working ok & downstairs radiators & other rooms ufh, it’s just the living room ufh that doesn’t seem to be getting warm.

looks like it could do with flushing through for starters, would get some one in that does under floor heating,
and not just any old plumber.
