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.

I had a Redring electronic that had two cookers in it and one broke
