My current set up of a free standing gas boiler, Baxi Boston, which provides
hot water and central heating is now 11 years old.
It is prone to breakdown and it takes nearly a week to get my insurance to
provide an engineer to attend only to say "it is an older boiler we do not
carry all the parts". This means a further delay while the parts are sent
I am thinking of changing to a newer version however I would like to stay
with the conventional system with a tank in the loft ect. I have a power
shower which I believe you can not have with a combi.
I am not sure what is available in the conventional boilers and due to where
my current boiler is situated in the kitchen I would not be able to have a
drain outlet for a condensing boiler. I would be grateful for any advise and
recommendations on boilers as my search on the net is somewhat confusing and
the number of breakdown complaints does not give me any pointers to the best
I note what you say about sticking with a conventional boiler John - but I
would suggest you reconsider. My old Baxi boiler was over 25 years old and
despite remaining reliable I wanted to change. I'd always been 'anti' combis
because I knew of so many people who had them and did nothing but complain
about unreliablity and them taking an hour to fill a bath.
After a lot of hard research and soul searching, my wife and I made the
decision to go for a modern combi ( a Worcester Bosch 30CDi) . We had the
new boiler installed three months ago and are 100% satisfied with it.
For a start we have been able to get rid of the water tanks in the loft
(both the tanks for feeding the hot water cyliner and for feeding the
central heating system). The hot water cylinder has gone - and also the
airing cupboard it was in - enabling us to install an offset quadrant shower
cubicle in the bathroom where the airing cupboard used to be.
We had a 'power shower' over the bath before, but the new shower which is
fed directly from the cold mains and from the combi hot supply is superb.
Because the hot water supply is now at mains pressure it doesn't need a pump
and so you have the benefit of a power shower flow, without the need for a
noisy pump. I did have concerns about whether the pressure from the combi
would be enough for the shower - but it's great.
It perhaps takes a few minutes longer to fill a bath than it did before -
but certainly no longer and it's no inconvenience.
The radiators heat up much more rapidly from cold now - because the boiler
is only required to heat up the radiators and not a tank full of hot water
at the same time (a tank full that you may not use as well!!)
You say that because your boiler is in the kitchen there would be no drain
outlet for the condensate from a condensing boiler - but the condensate can
be fed directly into the drain from your sink - it does not have to empty
into an outside drain.
Of course the decision is yours - but unless you can demonstrate that a
condensing boiler is out of the question, you are required by law to have
one installed. I am now a complete convert to the benefits of combis and
have no regrets at all about switching. We now a more efficient central
heating system. Cheaper hot water because the boiler only heats the water
that is required - not a whole tank full. More space in the loft now that
all the tanks have gone - and more space in the bathroom now that the hot
water cylinder and airing cupboard have gone.
Have a think about it!
the reasoning and benefits do look very sound and I am aware of most of
I have converted my bathroom and we no longer have a bath only a very large
shower area.That is a plus I suppose.
Your comments about reliability was one of the issues raised when I have
spoken to friends on their boilers.
However I am happy to say at this moment in time after a visit and repair my
boiler man said the boiler is sound and will last for a couple of more
years. So the decision is on hold!! However I will file the information you
Once again thank you for your excellent reply
