Gentleman-

The input cold water supply is about 13C
At full heat (around 43C on the same thermo) it produces about 2.25litre/min

The 2.25 figure seems to be about half what one might expect with a 9.5kw
system

Any advice much appreciated!



It can't be running at 9.5kW and have that throughput.

Unless there's a significant leak
