I have a Worcester Bosch boiler Greenstar 37CDi that is about 8 years old.
I have noticed that our radiators get very hot. So I have turned down the temperature to it's lowest level - but the radiators remain very hot. In fact it appears that the temperature control is having absolutely no effect whatsoever. The attached picture shows the situation. The boiler was serviced about 6 months ago and I have been observing this problem for about 4 weeks. I have tried resetting it, as well as turning it off completely.
I don't know if it is relevant, but even with the hot water temperature turned right up, our hot water is only *just* hot enough for a bath or shower. It has been this way since the boiler was installed.
I would appreciate any help or advice, as I can't really afford to call out a heating engineer at the moment.
