Boiler isn't happy, service engineer says it's because our flow rate from the mains is only 4 or 5l/m instead of the 8 or 9 we should be getting. I suspect Thames Water will do fuck all about this.
He suggested a booster pump for the boiler supply, but warned that as it would draw from the mains the cold supply to the shower etc would be reduced so the mixing at the shower could be out of wack. Just looked into whole-flat boosting but it looks like we'd need a tank... sounds expensive.

Anyone have experience of this?
