Help! 
I have a Suprima boiler ( always tempramental )which yesterday would not let me turn the CH off at the control panel. Today, I can only get the CH to work by calling for HW. If the HW reaches temperature, the radiators go off. Incidentally, if I use the main house thermostat to try and warm the house up whilst the HW is NOT on, there is a nasty clacking noise from one of those little boxes in the airing cupboard ( 2 little boxes with an l.e.d. on it ). Any advice is greatefully received. Thanks.
