An Example Of Jerry’s Wiring
We found what was wrong with the heating this morning. Jerry or more possibly a tenant, has bypassed the controls and wired the underfloor heating valves permanently open.
In other words, they have been set to give someone a good boiling.

As the picture shows, it wasn’t even wired up properly. Note that the junction box was just screwed around the jumble of wires.
With the valves permanently open, the temperature will of course just rise and rise, as the individual zone controls can’t switch the water off.
Note for safety reasons, I’ve swirched the whole system off, using the big red knob on the right. Once boiled, twice shy.

I guessed you must have had a fault something like that. Looking at the pipes at the right, Jerry’s plumbing doesn’t look much better.
Hope the controls work better now.

We’ve not fixed it yet. I suspect there might be other faults. After all it could well be, that the wiring has got burned out and the bypass was to get it going again.

[…] This would certainly explain the very dodgy and crude wiring in the heating manifold. […]
