Hi folks,
We recently had a 30m2 extension added to our house, we had a local plumber install UFH into this, along with new boiler and radiators - all the work was done by this plumber.
We've had issues with the UFH not getting up to temperature (flow temp is only around 25c and room takes 5+ hours to go from 18c to 19c). I've tried several times to get our plumber to come back and fix this but he's getting increasingly shifty which has me worried.
I'm looking for some advice on if what he's done is correct, and if not, what needs to be done to fix it, I am also getting a different plumber to inspect the work and give their view. Onto the questions:
1. The system is currently Y Plan with a 3 port valve - my understanding is this should have been converted to S Plan as part of the UFH to allow it to be controlled independently?
2. The flow/return for the UFH have been connected via a T from the flow/return to the boiler, but this has been done before the main system pump - my understanding is the T should be done after the main pump?
3. If 1 and 2 have been done incorrectly, is this likely to be the cause of the UFH not heating up correctly?
