Thermostatic shower/combi boiler temperature problem?
I need to somehow trick the shower into thinking it's never hot enough, so it shuts off the cold water going into the valve, and then i can just control the temperature using the water pressure going through the combi. Thought i could do that by removing the cartridge which has helped, but not enough. I have worked out the problem is definitely not to do with the boiler, as the hot water inlet on the shower valve is red hot, while the water is lukewarm.
The actual make of shower is not mentioned on the manual - it's a victorian style one from MFI.
