Just installed a new Triton T300si (one of those with a remote heating
pack).

Its delivering barely over 2.5l/min on half heat setting = just about warm
enough for a shower. Pathetic by any measure.

Its a replacement for an old knackered 8.5Kw... but the one delivered
approximately TWICE the flow rate (certainly comfortable) at the same
temperature setting.

There is NO problem with the plumbing or water pressure on the input (with
the mains pressure at full the water is almost exploding out the taps in
the
same bathroom)

Could anything else be up? wiring???? Or is it really just that crap?
(flow/temp charts in manual seem to show much better performance but its
difficult to get an exact measure of output temperature to be sure)

thanks in advance.



is the input temp very cold?
