Im looking for a 24h CH heating timer programmer, that has separate water
and heating timer settings.
To be specific I want the water only to come on at a set time in the
morning, and then the heating only to come on at a set time in the evening.
CH is a Y plan.
Cant seem to find one that will do this.

They nearly all do this, so long as they have "independent" mode:

Thanks
two channel is the term I should have been looking for
Do you know if these come with a decent wiring diagram?
I will be replacing a Honeywall st772 timer

One way of achieving what you want to do is to use a programmable thermostat
on the heating side. Then set set your original timer with HW on 'Timed' and
CH on 'Constant'. The *actual* timing for the heating is done by the
programmable stat - and can be completely different from the HW times. It
also means that you can have different room temperatures at different times
of the day should you so wish.

I haven't seen a new programmer not capable of this in the last 20 years,
apart from the mechanical ones.

Are you *sure*? Most programmers I have come across have only got *one*
timer. Whilst they provide independent *control* for HW and CH - such that
each can be either Off, Timed, or On constantly - if both are set to Timed,
they both come on at the *same* time. The OP wants one with independent
*timers* for HW and CH.

I don't doubt that such timers exist. I just haven't seen one on my travels.

The Horstmann CentaurPlus C27 will do what the OP wants. You can set
separate times for CH and HW.

Pity I can't get it to work as a replacement for my Landis & Gyr RWB2 -
see the 'Horstmann CentaurPlus C27 replacement for Landis & Gyr RWB2:
wiring problem' thread below if you can help.

I have had one of these for 3 or 4 years:
http://www.thermsaver.co.uk/heating_controls/qe2.html

It has separate and fully independent time programs for DHW and CH. It also
come with helpful wiring diagrams for different setups.

I haven't fully researched this, but every timer I considered was able
to control the HW and CH independently, but are often shipped with
them locked together for those whose system requires the HW to be on
for the CH to work.

But there's a world of difference between *switching* independently and
*timing* independently!

Locking together only really applies to gravity HW systems, thus ensuring
that the boiler fires when you select just CH. But even when not locked
together, most programmers don't provide independent timing programmes for
CH and HW. A few do, as has been reported here, but it's not too common.

The Grasslin TOWERCHRON QE1/QE2 I mentioned earlier can be set up for
either gravity of fully pumped and, as I said, offers fully independent
timing.

I was really looking for a 24H timer to achieve this, as due to my work
shift patterns I have to reprogram the timer settings every 4 days.
so that I have hot water to shower when I get up,
im not in the house long enough at the getting up time to warrant running
the CH.
and a warm house to come home to.
As you correctly say there are lots of programmers such as
http://www.discountedheating.co.uk/s...mers_1105.html
which control the water and CH but NOT independently.

which control the water and CH but NOT independently.

I fitted a Honeywell ST6400C....does just that. Here's the user

What I mean is this. If they've only got one timer, you can still have
independent control of CH and HW to the extent that you can have (say) HW
Timed and CH Off, or HW on continuously and CH Timed (or any other
combination of Off/Timed/Continuous.

What you *can't* have is CH and HW *both* timed but coming on at *different*
times from each other. For that, you need the programmer to have *two*
independent timers - as indeed some - but by no means all - do.

I *know* that - which is why I was warning the OP that simply having
*independent* control of CH and HW wasn't enough! Some of the earlier
replies implied that *any* programmer which had separate switches for CH and
HW would do - which is untrue.

dunno. I have *three independent* settings for up to *THREE on/off periods
per day EACH plus one hour override or 'advance to go ' settings on all
THREE channels. Or disable any or all channels.

Honeywell I think.

Never missed a beat it hasn't.
Unlike the MV it drives...
