Our current boiler is 1990 Glowworm Hideaway, CF60, chimney flue,
which may need replacing in near future. It is installed in kitchen,
using the original as-built lined brick chimney. There are no
convenient outside walls on which to fit a wall-hung, balanced-flue
boiler, nor drains for outlet from a condensing boiler. I understand,
Glowworm do not make this or a similar model any longer, and I was
wondering if anyone had recommendations for a suitable replacement, in
the same location. Any advice would be appreciated, thank you.

Could a flue be installed down the chimney? Most manf show flue specs on the
installer web pages. (Mine can be up to 23 metres long)

Condensate should be possible somehow in a kitchen - have you considered
every possible solution?

Have you considered locating it in roofspace?

Why? If it's working, leave it alone. If it isn't - well you'd
wouldn't be talking about "near future".

It's unlikely that you'll get payback on a replacement boiler. And
spares are probably available.

Well all new boilers are condensing now and all are blown gas and
domestic sizes are room sealed. The flue can go out vertically or
horizontally, some boilers have separate (non concentric) air inlets
and combustion gas outlets. The max. length I have seen was three
meters. I suppose these could be installed in a chimney, they would
need to go right up to the roof. Probably the chimney would need
considerable knocking about even if feasable.
You might have to consider resiting your boiler, I have even seen them
in the roof space. This means more lots more expense as the flow and
return pipework would have to be rerouted also gas and cold water.

My old cast-iron Glowworm back boiler was 30 years old when we moved.
In that time it had never broken down. Last year's winter quarter took
£200 of gas, 40 percent of the annual total.

To replace it made no economic sense, and no practical sense either,
as the space it left could not be used for anything else, and finding
space for a new boiler in a small semi would have been problematic.

I suggest you determine the availability of spare parts for your
current boiler and consider keeping it, having it serviced by someone
who, unlike BG, will not persuade you to have it changed.

A possible replacement could be the Baxi condensing back-boiler, the
flue for which would run up your current chimney, but I've no
experience of these.

Thank-you all for replies and advice. It seems, that any replacement
would be balanced flue, as CF no longer made, which would be a
problem, due to distance from outside walls. I think I shall get it
serviced soon by local heating engineer, see what his opinion is.

I do not think you understood the thread. You can fit another boiler in
the same position as the Hideaway - on the back wall of the fireplace.
It will be room sealed which is a bonus as the drafty outside the air
vent can be sealed up.

The boiler exhaust can be extended up the chimney using cheap high
temperature domestic waste pipe. The air intake can be at ground level
or another plastic pipe run up the flue. A link to Keston was given who
specialise in this sort of thing was given.

As one thread highlighted, a condensate pump was linked to. If you have
an adjacent drain then there is no problem. The pressure discharge can
be fed into a HepVo trap and taken to the drain as well.

Also, as been suggested, a loft installation of an Avanataplus 35C or
39C combi is a nice out of the way installation, meaning the chimney can
be sealed off. I would suggest this option if the mais water pressure
and flow is fine.

If no alternative then the Baxi Bermuda is an option. Baxi were crap,
but since the Dutch have taken over the quality is rising.

Take no notice about fixing it and replacing it makes no economic sense.
You will save 40% on your heating bills by changing over to a proper
boiler. Go figure.

I have figured and a modern boiler makes no economic sense
40% off my gas bill might be £250 pa. Knock annual service costs of
modern boilers and it will take longer than that new boiler will last to
break even.
30 year old cast iron for me until such time as I can no longer buy the
odd parts it needs such as a thermocouple every few years.
