Sorry to start another "Which combi" thread but my choices appear to be
limited by the width of the casing. At 400mm it seems to boil (sorry) down
to the Vokera Compact 24, Ariston Microcombi 23, or Ariston Microgenus 23.
My current boiler is a similar spec to these, and is quite adequate, so I
won't be considering a higher output. Much as I'd like a condenser, the
budget won't quite run to it and I'm slightly put off by the fact that our
biggest local trade outlet (6 permanent counter staff) doesn't stock a
single condensing boiler.

Does Fred Dibnah shop there?

Did I read somewhere that Ariston have a
2 year guarantee? Any other reasons
to go for one or the other?
Thanks in advance.

I have a Microgenus, the more powerful model. So far it is fine after 20
months. A bit noisy, but it is in a solid cupboard in the bathroom so noise
is not an issue. The Microgenus is well specced, it even comes with a
built-in filling loop. It has a reduced gas rate for CH to reduce cycling
and a built-in two minute anti-cycle function. Run a Honeywell CM67
stat/programmer (or equiv) which also has an anti-cycle function, they work
well. It has a two year guarantee and a 5 year guarantee on the plate heat
exchanger. It is easy to fit. I was talking to the Aniston service agents,
their service guys rate the Microgenus and say it is quite reliable. Parts
are easy to replace

Look at the Worcester-Bosch Junior combi. That has a v small casing too and
v simple inside with no 3-way valve. I would probably go for the Junior if
buying today. No matter what combi you fit, fit a phosphor de-scaler to the
cold feed and replace the cartridge once a year. You should do this on any
water system.
