A bit of background first...
We've had no-end of trouble since our Isar HE24 combi was installed around 2 years ago. A few weeks back British Gas finally got to the bottom of the problem (the big problem we had was intermittent hot water). It seems the root cause was that the system wasn't flushed out before the combi was installed.
BG have now flushed the system and we have a good flow of hot water now. However, some rads appear luke warm whereas others heat up fine. They've been bled which doesn't appear to have helped.
The rads in question weren't great before the flush but now appear to be worse.
All ideas/suggestions welcome.
Thanks.
