24 KW combi or system boiler ????
Has the pump been checked? The fast temperature rise could be due to a faulty pump, which could be the reason for the very hot pump. In any case the pump is installed incorrectly as the shaft should always be horizontal, not vertical as in your pics. The installer should have drawn this to your attention.He isolated the C/H circuit & found restriction in boiler or coil.Temp rises fast on boiler 49 degrees cent to 74 degrees in 40 seconds 9Been told this could be blockage in the heat exchanger )
The casing on the C/H circ pump gets that hot I cant hold my fingers on it.
This is only true if they are one-direction TRVs. If they are modern bi-directional TRVs it doesn't matter which end they go. Look on the metal body of the TRV for one or two arrows. If there is only one arrow the TRV must be installed so the arrow shows direction of flow (towards rad on the flow - hotter pipe, away from rad on return - cooler pipe). It there are two arrows at 90 degrees, it's a bidirectional TRV and can go on either end.2 rads have TRV's at wrong end.
Instead of moving it to the other end, the TRV just needs to be turned on its side, swapping over the inlet and outlet. Having the control horizontal is theoretically better as it does not get influenced by the heat rising from the pipe.The TRV's only have one arrow and the 2 that are wrong point into the rad but they are on the return side.
Consider it done ...
u got a blockage of somesort in ur system mate
Suspect pumpIt is very hot.I can not keep my hand on it.
Try running a magnet over the pipework near the pump, if it sticks then theres a good chance theres a blockage. Prime candidate is where the cold feed from the F & E enters the syatem or neutral point as its more commonly known.
