Thanks, that helped a lot.
Found it at the top of the pipe ( ours was on the left side ).

you have to remove large white front panel and the stat is on the right hand side of the heat exchanger on one of the copper pipes the " red button " is about the same diameter as the lead in a pencil and is in the centre of the stat which itself is only about 20 mm diameter easy to find once you've found it good luck
