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.
