Exactly sweetie, I *don't* have a hot water cylinder, hot
water is supplied on demand by being heated as the cold
water flows through the boiler. If it flows flowly enough to
be heated to a useful temparture, it's flowing too slowly
for a decent shower. If it's flowing fast enough for a decent
shower, it's flowing through the boiler too fast for it to be
heated up, escpecially now that the cold supply arrives
at 8 degrees since the snow stared. This is why I hate
non-stored hot water systems.

That's the first time I've heard of a 'combi' system.

with luck, it will be the last as well.

spawn of the devil.

A combi is to what we used to call a 'geyser' as a wimnd turbione is to
a traditional windmill.

I.e. a really crap idea dressed up in modern clothes and sold on the
basis that it actually does something useful after all.

The only 'combi' I have used that really worked for hot water, was the
one my sister had in germany. It lived in the basement and was the size
of a family car. That actually could produce a hot shower.
