What a difference to my heating. House so much warmer. Only issue is that my bath runs a lot slower than it did but still glad I replaced old boiler.

Excellent and friendly staff. Slightly disappointed with finishing off work. Looks a bit messy. Maybe it was that my expectations were not managed. Other than that, very happy.
