You wash vegetables in hot water?

Oh dear. First of all this is unnecessary. Secondly it begins the
cooking process earlier than necessary which results in many of the
vitamins in them being broken down.

Patronisme as you wish, but don't tell me that it's fun to wash your
veg at 5 or 6 degrees cold water. 10 or 15 is much better. In winter,
you cannot get this without a mix of water. If you wash veg for half
an hour in 5 degrees you will beg for a combi. At least everybody I
know with a combi does mix a bit of warm water to keep the fingers
from going numb. Assuming that I am washing veg in hot water is
deliberate misunderstanding, kind of serves my point really.

Even quite large combis can only deliver 15-20lpm of water at 40
degrees in the winter. THis is marginal for one shower, let alone
two.

You have obvioiusly never taken a shower in a combi system with decent
mains pressure to call it marginal. Hence, I recommend case closed,
keep your system and I will keep mine or rather I will have mine. Two
showers btw is not the issue. I do not question that combis have
problems serving two showers. Whether or not your tank system would do
it for me is not the issue because I will never want a house with more
than one shower, regardless of the number of children :-)
