No. They have re-circ of DHW draw-offs.

Then they're not an 'instant' heater. Which as you may not have noticed
starts and stops on water usage. If you're circulating hot water all the
time so it is instantly available, this is a form of storage system.

Perhaps among the other things
you desperately need to learn about is the
meaning of 'instant'.

Perhaps among the other things you desperately need to learn about is
not to comment on fields you know sweet FA about.

But I've just explained it for you? Was it too difficult for you to
understand? Or perhaps like Humpty Dumpty you expect words to mean what
you want them to?

Here is this Plowman giving you advise on CH..read on...

This what he wears, yes he does...he said... "Well, I got a rather flash
pair of DeWalt boots from TLC, so there.;-)"

Sad isn't it. Big yellow boots. Yes. big yellow boots.

Dear me, your needle has stuck - again. Can't you try and think up a few
new insults?

FWIW, for one who so avidly reads and quotes catalogues, haven't you ever
noticed the colour of DeWalt protective foot wear?
Or perhaps this indicates your lack of interest in such things - sitting
in your office all day dreaming?

He also attempts to give advise and criticise views on heating, yet he
said about his gas boier.......

"Mine managed over 10 years without being touched before it needed a
clean. 'Sooting up' once it starts, happens very quickly."

He didn't have his gas boiler serviced for over 10 years, and knows all
the answers in this field - he thinks.

I'd heard how people like you use a hacksaw for everything so decided to
save about 1000 quid in 'routine servicing'. Of course I'd never stint on
safety checks. But they don't make the same profit as ripping things apart
for no reason, do they?
