Can any think what the problem here might be.... underfloor heating pipes not warming up. Am I correct in expecting the polyplumb 12mm plastic piping to feel warm when the boiler water is <70 degrees C? Or at least the metal compression joints should be feeling warm/hot?
Background: purchased a house with polyplumb underfloor heating pipes in the kitchen, I sussed out there was leakage so I took the tiles up and repaired screw damage with metal compression joints. Now when I turn the valves marked R and F (Return & Feed?) I know there is water flowing through, but its cold even when the boiler is on heat mode. The only controls are two screw valves (on the R and F pipes) and a radiator control knob (although the turning knob has come off). The R and F pipes are roasting hot, but water in the plastic underfloor pipes is cold (I determined this by opening one of the compression valves I put in to repair the leaks - to bleed out any air out).
Keen to get to the bottom of the issue before screening and tiling back over!
What am I missing here? Is the radiator control valve being absent the problem (I assume when the heat setting dial is missing, the valve is fully open)?
