At present I have a Baxi Combi instant 105e. I'm thinking of replacing this with, possibly a Baxi 105HE. Apart from the obvious need for the condensate drain, would the new boiler fit as a direct replacement for the 105e?
I have no idea, the chances are that the connections will be in the same order.
You could do worse than to look through the BoilerChoice FAQ.
Thanks Ed.
I don't think they use the same jig so there will be some adjustment to match the pipes exactly to the new jig. This will be fiddly rather than difficult.
Why are you changing?
They certainly look similar, but I can't put my hands on the installation manual for the old one.
The old one is showing signs of its age, also the condensing one should be a bit more efficient.
Are the installation handbooks downloadable from the manufacturer? that may give a clue.
