Went to a job yesterday, cust says UFH stopped working. I cant see that it ever worked.
20m2 conservatory single loop from a blended manifold. He says it had 100mm kingspan in, 120m 16mm uponor and 130mm of CONCRETE over the top of it. It had a flow temp of approx 45deg. Also he said he always had it set to timed on off.
The blender that was being used was just a standard undersink blender 15mm 18lm tmv3 ( i think this should be ok but never saw one used before) what you think?
Im tempted to alter the manifold too as at present the mix port on the blender also goes to the return of the boiler and flow of the UFH circuit.
The pump is setup so that it sucks through ufh return but then mixes with the blended water and the boiler return which doesnt seem right. Ill draw a pic in a min.
Now in my opinion the setup itself will never have worked. I have suggested he needs a higher flow temp (not sure on the max on the tmv3 and to use a setback programmer, but even then its gonna take forever to heatup.
What would you suggest the min flow temp should be and also what is the heating output of 120m of 16mm?
I cant find any charts
Cheers Gareth
