You have just popped my bubble. I assumed that a new one would be just as good. Don't they offer a 7 year warranty? I will take a look at the other options. Thanks.
My current Bosch Danesmoor is 20 years old and still running and burning well. It is regularly maintained and frequently requires minor parts. Obviously, it is costly to run because it is not condensing, and I expect that the parts will become hard to get at some stage. I want to replace it...
