Fitting a new gas boiler

[Guest]

Folks,

My wife, two kids and I live in the UK in an end terraced house. We're
due to have our central heating system revamped. Three bedrooms will be
getting their own radiators, along with one large one in the living
room, another small one in a hallway and another towel rack/rad in the
bathroom.

I would like to get the most energy efficient condensing boiler I can
(88%), but my gas-man tells me that there is no suitable space on an
outside wall. Our current boiler is in a cupboard in the centre of the
house...upstairs. It's impracticle to have a condensing boiler as the
flue, he tells me, would have to be almost 20 feet long to come out the
roof. This means that I'd have to settle for something 10% less
efficient, which should cost me an extra £50 to £100 a year in gas.

Anyone have any similar experience with heating upgrades? Are there
options we're overlooking?

Move the boiler into the loft?

=====================
Get a second opinion.

It would be a very unusual house that couldn't provide a space somewhere for
almost any type of boiler you choose. Do a 'google' search for condensing
boilers and note the different sizes and then look around your house for
possible locations - upstairs, downstairs, cellar and as suggested by other
poster, in the loft. |If you've still got hot and cold water tanks then you
can have them removed (permanently) and the space can be used to fit your
new boiler.

There is a type that was made in North America, a Lennox Hydra-pulse I
believe it is called, that uses a combustion chamber arranged like a pulse
jet engine. A friend of mine has had the forced air version for about 15
years. I don't know if the boilers are still being manufactured.

The "power vent" varietys, which use an exhaust blower are quite popular,
both for hydronic heating systems and for domestic hot water.
I should think that something similar must be available in the U.K.

This is not an unusual situation, think of how it works in flats where there
have to be long flues. There will be a number (not many mind you) of
condensing boilers that have a long flued option that may let you have the
boiler exactly where it is now. Here's a couple to get you started on your
search:
Keston Celsius 25 - inlet & exhaust use 50mm mupvc (plastic) drainpipe of
up to 15m (I think) so it can be very easily accommodated but not easily
bent if you are trying to put in down a chimney with a dogleg ;-). Guide
price 675 + vat (at a discounter).
Eco Homtec EC25 (I think) - a high quality german boiler with loads of nice
features, many long flueing options, but a bit expensive at 1200 ish + vat +
prob 200 for the flue.

Get googling for details of these & come back if you have any questions.

Have also seen multiple Aristons in a flat complex & am pretty sure they
were a condensers.

Only regulations are that you have easy access, lights, and floorboarding

around the boiler.

I am not even sure that these are regulations. It is just that no sensible
heating engineer will work without them.

For **** sake, this is about as interesting as misc.rural.

>My wife is convinced that's against fire regulations when I suggested
the loft to her initially!

It's completely within regulations. I had the same doubts when I
first read about boilers in attics on NGs, but I asked my plumber
about it and he had absolutely no problem with it. We haven't moved
ours into the attic yet, but we probably will in the near future.

Go to:
uk.d-i-y
And ask there. They are clued up on UK systems. Best not to cross post.

Pulsed burners. Are they noisy in domestic usage.

Condensing boilers will be virtually mandatory in the UK after April 2005.
The minimum efficiency is rising to 86% minimum and only condensers can
reach this.

PVC venting can usualy go 20ft. Look into 93- 99% efficient boilers.
Yes there is a 99% unit made. Dont put it in the loft if it ever
freezes. 3" PVC is cool to touch and safe. You are talking Natural gas
or Propane I assume.

There is when it's on the wrong Newsgroup!
It's "Off Topic" of certain newsgroups.
I've trimmed enviornment.conversation from NGs.
Now up your flue and I hope you get your boiler working.

Of course there isn't. Do you mean to say you read every message on
every newsgroup you are subscribed to?

Er, no you haven't, because this is where I am reading the thread!

Now up your flue and I hope you get your boiler working.

My boiler is working perfectly, thank you. But then I'm not trying to
install a new one. It was someone else who was asking for advice on the
subject, which you would have known if you had read every message, as
you implied you did
