But the gains are terrific.

So you claim. However, claiming that
capital costs are lower is simply
false. The capital costs are over double.

For what you gain it is not. Putting a new boiler on an old systems adds
little value.

They run out though. No waiting for
showers with a combi eiether. Ever
used one?

Yes. You have to wait much longer,
as you have to wait for the combi to fire
up and get up to speed, unless you have
one with built in storage.

Are you having a laugh? You have to wait for the cold lag to empty in
adraw-off in a storage system.

And "two" high pressure showers can
be running all day. Can't get
that with a storage system.

Of course you can, if the boiler you choose
has sufficient output (and the
cylinder has sufficient input) to cover the
showers, then a storage system
would also not run out.

The boiler would have to be as big as the combined two combi's outputs, as
when the stored water depletes you will be running on boiler output.

It is NOT. You require zone valves,
which take up space and the control
wiring and knowledge to do it to boot.

It's hardly rocket science to wire up
S-Plan systems. The wiring is
exceptionally simple.

The wiring is NOT simple, especially to the uninitiated. The valves tale up
space and are another thing to go wrong which is expense.

It is NOT. See above.

It is extremely simple.

It ios NOT. see above.

In the US many are going over to
multi-points that output 200,000 plus
BTUs/hr. On-demand hot water is regarded
as much superior to stored water.
Bosch, Takagi and Rinnai are the big players.
Two combi's is roughly the same output.
The largest output multi-point in the world is a Takagi.

Don't talk rot.

You haven't a clue. You have been taking Andy Hall pills.

They have crappy direct electric
and gas heaters that have
the efficiency of a lit fart. They have
very few instantaneous gas heaters
actually installed, although 24kW
instantaneous electric heating is common
enough, with the obvious limitations thereof.

You still haven't a clue. Tankless on-demand (instantaneous, multi-point in
the UK), is increasing market share in the USA. Want 50 litres/min for 2
hours on end? Get a Takagi multi-point at 380,00 BTU/hr.
