I'm a novice with a choice to make between a Vaillant Turbomax 824e
or
a
Worcester Bosch 28i Junior combi (running 9 rads), and I'm wondering
whether
anyone has any comments on the Vaillant's 'Aquacomfort' feature
which
seems
to provide 'instant' hot water.

Is it the kind of feature which should influence my decision?

Sincere thanks for any advice, it's tough learning about these
things
from
zero!

This feature has been around most middle market+ combis for a
long while. All it means is that the innards are kept hot on standby
in
readiness for HW production. The feature is user selectable.

IME this means the boiler fires perhaps a couple of times an hour for
about 30 seconds each time.

A reasonable make like the W-B might well also have this feature.

I'm pretty sure the Junior won't do this - it's the type with some sort
of
combined primary heat exchanger for CH and DHW rather than a secondary
for
DHW. (Very nice build and simple inside: just a flow sensor switch in
the
cold inlet, no diverter valve etc. I've just hung one but not fired it
up
yet so we'll see how it flies .....)

I have heard a few good reports on this. How much do they cost? I know it
is
only a low flowrate model, but must be ideal for shower only flats; small
and simple.
