General   (General discussion, talk about anything.)

Tom. I have in the past posted that a few years back, five of my friends happened to be plumbers, and although they installed combies for others, they had eschewed combies in their own homes. (Two boilers)

I never quizzed them about why they had chosen to do this, but I am pretty certain that one thing they would have said is that when it goes wrong, can throw in a replacement pump/valve or whatever, and up and running again at minimal cost.

You have previously told me that combies have improved a lot, which of course I do accept.

I wish they were still around, so I could ask if they would still choose such an option today.
