You should consider a combi first. They make some fabulous models
now.

I'm sure there are but I still don't want one :-)

Having paid particular attention to boiler posts over recent months,
the
problems encountered seem to relate to the complexity of control and
electronics in the modern condensing units, rather than whether they
include the hot water generating "combi" element.

Depends also on what flow you want. It's easy to get high flow in the
average house from a storage system to fill say a bath quickly - until
of
course that store runs out. But that's why storage cylinders are the
size
they are. And a fast recovery type will re-heat in the time it takes for
a
leisurely bath.
No domestic combi will match this flow at the same temperature, and
those
which get closest ain't cheap. There's also the problem that in many
parts
of the country water pressure is low in an attempt to combat mains
leaks.
This can reduce the potential of any combi system even further.
See the heating FAQ - it gives chapter and verse.

These are exactly the reasons why I don't want a combi.

But that was tripe.

Everyone I know who has been sold one on the basis of the benefits has
been dissapointed. Mainly because of dissapointing flow.

Then get a highflow combi. Do a search on this group for Alpha CD50 a few
satisfied users. who will confirm the flowrates. They will a bath as fast
as any storage system and no tanks or cylinders.

Can you run a power shower with that?

Ah he missed lots out. If you do have dire water mains pressure, this
usually improves when a new 25mm plastic mains pipe is fitted, then fit a
loft tank and heat bank. Heat banks are superb for mixing different heat
sources and ideal for solar. Have a pump on the tank to heat bank line to
give high pressure water at "all" taps. When the mains is updated in the
road then you can strip out the tanks and pumps and go direct from the
mains. Have an integrated heat bank running the CH from it. It is the
best solution and gives great scope and flexibility for the future too.

I suspect all rather more expensive than the £419 tank that I am going to
have fitted.
