Does anyone here have any experience of these German boilers, the Which best-buy for 2017? We need a new boiler and one installer has recommended one but we've never heard of them, some of the on-line reviews are good.
There are some old posts, 8 years ago or so, but wondered if there were any more current opinions.
We've had one for 18 months or so. No problems at all and our gas bills have fallen as it's a condensing boiler (as opposed to the old one that wasn't).
