I boobed with my earlier cry for help.
I said that the existing boiler was floor-standing.
It wasn't.

The lighting was so poor then that I couldn't tell!

I have now had some professional advice and need to find a wall-mounted
heat-only 15KV boiler whose flue is at the back, not at the top.

Any suggestions?

Not aware of any that have the flue at the back these days. However I
can't see that matters so long as you get one that will fit in the
available vertical space.

(typically a flue emerges from the top straight into an elbow, and then
goes out directly through the wall - so rear exit but above the boiler)

Do you mean heat only, or would system be ok as well?

There's probably the odd ancient thing on ebay with rear flue, but I can't see them being any real use. It may be time to re-site.

I rather fancy the Ideal logic Heat 15 but cannot find a picture of the rear
to be confident.

No. I want to make it easier and less messy, so a direct replacement of a
heating-only boiler (plus keeping an airing cupboard as such) indicates a
heat-only jobby. I have found a couple. Just waiting for some extra data for
the second one.

Thanks for the replies.

Yup, there are heating only boiler out there. Vaillant do their 400
range of models for example, which include some that can work on a
vented system. (they are also quite small so may fit your requirement in
more ways than one)

Keep in mind that the heat lost from the case on a modern condenser is
very low - so you can't rely on the boiler to keep an airing cupboard
warm - you would likely need a small rad in there.

(also modern boilers are full of electronics, and hence will be more
reliable if not kept in a room with a high ambient temperature)

The 400 range also have a rear flue option which the OP wants.

The 400 series was completely revamped in 2015 and they now have a newer
aluminium heat exchanger rather than stainless steel. The stainless
steel heat exchanger in the older models had a very high pressure drop
and gave problems where pump sizing wasn't spot on, also they were more
susceptible to clog up especially when used on older systems. I believe
the new heat exchanger has much larger waterways.

Aluminium heat exchangers with aluminium fins in acidic flue gas are a
bad idea.

Why are they less likely to clog, apart from having to be replaced every
few years?

Ah, that's handy to know. I did have a look a the pictures of the 400
series but did not spot the rear flue one, but had a feeling they might
have done one since its a popular choice for people looking for a heat
only boiler replacement.

Domestic gas has to be phased out by about 2030 to meet climate change
targets so an electric boiler with high efficiency supply could be
sensible forward planning.

If that really is the case, it's about time our government did the forward
planning as there's not a cat in hell's chance our electricity supply and
distribution could cope with everywhere having electric heating by 2030.
My gas boiler is 30 kW and my electricity supply 24 kW max.

And what method are we going to use to generate all that extra electricity?

It depends of course on other assumptions and who is making them. Eg
the Committee on Climate Change see natural gas lingering on until 2050.
Others though think it'll need to be faster as the 2030 targets assume
growth in the use of carbon neutral gas (e.g. hydrogen or biomethane)
and electrification (including heat pumps).

It'll probably start with a ban on sales of new gas boilers. (Note to
self: see if shares in CET Ltd for sale.)

Politicians can promise anything will be done by 2030, it means nothing. I don't know why people take any notice of such claims. Looking at the facts it seems more than a little unlikely.

A lot can happen in the next 10 years, technology wise. I'd agree,
though, that somebody is going to have to start thinking it through.

For now, homes could certainly have better insulation and use what
heating they have more efficiently. New homes could be looking at things
like heat pumps. And some folk could always put on a jumper ;-)

I feel we won't have to be concerned about 2030 and climate change,
don't know why.

An electric boiler driven from a gas power station will always be less
efficient than a gas boiler.

An electric heat pump might be reasonable, but you really need UFH with it.

To be fair, National Grid last year[1] reckoned there will still be 7
million gas boilers in 2050 (instead of 25 million in a "steady state")
on the "2 degree" model. So you have a good chance - unless of course
you are in an area where there's a compulsory switch to - say - hydrogen
