I've just been watching a Youtube video of a heating engineer fitting a 125 litre high recovery cylinder.
At one point in the video, he seems to be saying that if you run the coil on these cylinders at a high temperature, you will often end up with excessive stratification. So, the NTC sensor might be set to 60C, but the water from the taps coming from the top of the tank is dangerously hot at over 70C. Is this to be expected?
