Really appreciate all the helpI think it might be a good idea to get a g3 qualified engineer in to check the controls etc on your cylinder.
I have to leave now but will try and see how you get on later. Good luck.
The water is heated through the boiler (plus we have an immersion heater)
My message above was not accurate. What I meant to say was that the water leaving the tank (after being heated via the boiler) is 37C. When I check just the hot supply (isolate the cold) at the kitchen sink it’s at 16C making me think that the cold has mixed with the hot before it gets to the kitchen.
Sorry for my sloppy message
What’s the circulation temperature of the pipework from the boiler to the cylinder coil? It sounds like the first issue to sort out is why your hot water is only body temperature in the cylinder. I’d want to get the cylinder temperature to 65° or more before messing around with pipework, taps, valves & showers. It’s also worth checking your temperature equipment. 37° is body temperature: does the hot water from the top of the cylinder feel about the same temperature as your hand? It might seem like a daft thing to check but that temperature from the cylinder is surprisingly low.
