anybody using a domestic boiler and separate heat exchanger?
I can see there being inefficiency arguments but I think the indirect principle is the same as in the certikin genie.
But on the plus side there is a significant premium for engineers to service pool boilers and the warranty on domestic boilers is 10 years
