Looking for a combi for a 2 bed house, to be rented out. Gas man recommends
Halstead, but can't many positive comments via google, so any comments here?

Would be driving 5 rads and a shower in the bathroom and a sink in the
kitchen. Chap was on about 32kw unit, saying the flow is better than a 24,
but for such a small house, flow seemed be less of an issue as there are so
few devices which can draw hot water at the same time.

Cheers,
Matt

Is there a bath? If so a 24 would be pitiful. For just a shower it might
be ok so long as nothing else wants hot water at the same time.
Personally I would say 35kW is realistic minimum.

Can't go far wromg with a Bosch: Worcester Bosch in this case.

Any combi will give a reasonable shower. No combi will acquit itself very
well when you've got multiple demands for hot water. Even the biggest
combi is less than twice as powerful as the smallest: if you're fitting
out a larger, more upmarket house you'd want at least a storage combi and
possibly a full storage system. For a small, non-luxury house I'd fit a W-B
greenstar 24i junior and a thermostatic shower valve.

Just because you're paranoid doesn't mean they're not out to get you.

Another reason for getting a reliable one with good parts availability and
loads of engineers who know how to fix them.

Backup is certainly an argument in favour of stored-water systems, but for
a 2-bed house it's difficult to justify the space and expense.

We got a Halstead combi as part of a 'deal' (don't even ask) about 3-4
years ago. Apart from a slight leak in the diaphragm alst autumn it's been
reliable, simple and ... just there....

Yebbut even if you only have *1* device on i.e. a shower, then 24 to 32 kw
is going to make a big improvement. If you want to fill a bath, it will
make a big difference in the time it takes.

Bear in mind, with a combi you've no immersion heater back-up if the
boiler breaks. That means if it does break, you've got to fix it quickly
or have very unhappy tenants.

You can fit in in-line electric instant heater in the DHW outlet. Small and
cheap.

Go for a Broag 39C with outside temperature sensor.

Overpriced and 5 years out of date.

Any combi will give a reasonable shower. No combi will acquit itself very
well when you've got multiple demands for hot water.

You must get to know more about combis. An ATAG 51kW will do two bathrooms.

Even the biggest combi is less than twice as
powerful as the smallest:

More. Want a 72kW? MAN have one.

Out of date. Look at Broags. Cheaper and far better. Bang up to date.
Better still buy an ATAG or Atmos.

But only 7-10kW and require their own high-capacity circuit on the CU.

Better than nothing but not a complete supbstitute for a working combi.

Boiling a kettle is even cheaper - and just as effective.

It is only backup and will give you a shower and hot water. Some state they
can run two taps. They can but not on full flow. Many can use the old
immersion cable. The point is that a combi should not be dismissed as there
is no electric backup.

This is £116. As will be backup only a cheapish one is usually fine.

These are 9kW to 12 kW in-line instant water heaters. They can do a shower
and a tap or two. The shower, not great, but gets you wet and hot water
available, at a tap or two. Great for backup if a combi is down.

There are lots of other makes around.

Or why not that old bit of bellwire? Neither is remotely close to the spec!

If they can be run off 'an old immersion cable' then they are no more than
3 kW - so as I said makes more sense just to use an electric kettle.
And if you think 3kW will 'give you a shower' you know even less about
heating matters than anyone even guessed before.

May be - but not even a plant pot could get a hot shower from a 3kW
instant heater as you suggest. So **** off back into rehab 'till you learn
something about heating.

Interesting that both times you've snipped the relevant bit pointing out
your mistake and reposted your asserion that a 3kw feed is sufficient to run
a shower.

It seems to me that the definition of "a total plantpot" would probably
include the sort of loony who tells the world that a "9kW to 12 kW"
instant water heater can be operated when wired to "old immersion
cable".

That sort of advice is what we call "stupid".

Probably because the catalogues that he gets his info from don't do cable
sizes.
