I am always amazed at the ineptitude of so many installers!
Yesterday, I saw a 637 beautyfully fitted with 28 mm gas and heating pipes! But all in a house with a heat loss and radiators of just 12 kW.
All under a BG service contract but the earth bond went 2 m and stopped there. The unvented seems to have an orange EXV.
