Boxing in gas pipe

[Harry Bloomfield]

To add to what others have said, a friend of mine runs a gas company and he wouldn’t have a combi in his own house. He gets most of his guys’ work from combi callouts. Having said that, no doubt there are circs when a combi is a good choice, but I suspect plenty are installed when it isn’t.

Likely because - at a guess there are more combi's about than system or heat only boilers, but combi's do tend to be much more complex/ much more in the boiler's case, than other types and therefore much more to go wrong.

Agreed, and why is that? Often because combi is pushed by the installer when it's not the best choice.

Maybe a tankful of hot water in the roof space might be a worry,

Better to have the hot water cylinder in an airing cupboard to air your clothes.

I agree entirely.
