Isn't a flat plate heat exchanger dispensed with on the intergas Combi. I think dhw gathers heat on the primary heat exchanger?We fit them at work, only fault I had was on one, and the fan was stuck which I freed up, but it then made a racket, got them out under warranty. Only a few things I don’t like about them: the expansion vessel is at the back (boiler off the wall to change), aesthetics, and after heating has been on when you open the hot tap comes out extremely hot, so have to run for about 30 seconds or so.

Maybe need an anti scald valve?
Sounds like "undertrained" is a very apt name for you... you shouldn't get the extremely hot water you describe unless the boiler is being set up to ridiculously high, inefficient flow temperatures. Fit it properly with decent controls and it's not an issueYes I think it does, I mentioned TMVs to bosses, but a TMV on every outlet?

That's just madness. They won't even condense with an 80°C flow temperature - it's just too high so you end up chucking a load of heat out of the flue. 70 is plenty usuallyYes it is, that’s why I chose it. I think my “training” has been poorly delivered and that’s why I joined this forum (perhaps I’m also a bit thick). When these boilers are setup, usually by a contractor or fitters, they set them up on usually the max ratings, so I think 80 for heating and 65 for dhw.
Not a DIY job I'm afraid - in common with most other makes of boiler, the case forms the safety room seal and as such should only be removed and replaced by a Gas Safe Engineer capable of carrying out the regulatory 26.9 checks on completion. DIYers should not be removing it to do anything at all.The Intergas Rapid has the expansion vessel on the front swinging out on a hinge. A DIY job to replace.
