    I've installed a few and i've never had any issues with them. It's a great system.

    As far as I am aware you can pipe it as a four pipe or a two pipe system by blanking off the pipes that arent needed. It is a great system as it is one of the only boilers that actually condenses, I have had one in my house for the last three years and have had no issue with it at all. Has anyone ever had a issue with them?

    You can only use the weather compensation on the 4 pipe configuration. You can pipe them 2 pipe but you can't use the outside stat, if so when hot water is on only on a mild spring day or in the summer it wont heat the cylinder.

    All the new boilers condense.

    This thread is ancient :-)
