“First things first: they are not Engineers, they’re Technicians ”
if you over simplify what it is they do perhaps.
ill let them have the title heating engineer having seen what some of them can do…..(some of it involves more calcs and design work than the stuff i do as an engineer)
much like a kwikfit fitter is a part fitter not a mechanic – a mecahnic fixes things he doesnt just replace consumables.there are extremes at both ends of the title.
4-500 quid for a heat exchanger – how expensive was your boiler – a replacement wont be much more unless its a monster im sure – glow worm aint a premium brand are they ?
i dont buy the bomb proof part – more like cash cow thats easy to fix 😉
