Your choice of boiler
depends on where it’s being installed. Different sized establishments
all have different needs – and suit different boilers. Whenever
we give you a quote we will always recommend the specific machine
that is best suited to your individual requirements. Here, though,
is an overall guide to the different types of boilers that are available:
Combination boilers
Combination boilers, as the name suggests, combine most of the components
of a conventional system i.e. boiler, cylinder, pump, control valves
and thermostats. Together, these are housed in one unit (The Combi).

| |
The
technology involved with this type boiler has improved at
a dramatic rate over
the last five years.
Where, not so long ago, a combi would only produce nine litres
of hot water per minute at 35°. Nowadays they can produce
up to
eighteen litres a minute at 35°. This is why they now
account for most new boilers found in the UK today.
In general, combination boilers best suit flats
and small houses. |

Conventional
boilers
A conventional system (as opposed to a combi system) is one where
a cold water storage tank, a hot water storage cylinder,
a heat only boiler and separate controls are installed to provide
primarily a greater volume of hot water.
|
|
| |
This
type of system is more suitable
for larger houses with two or more
bathrooms where hot water demand
at several taps is likely to be
simultaneous.

Condensation
systems
From April 2005 everyone’s had to fit condensing boilers as
part of the Kyoto agreement. This is good newnews for the environment
since it has reduced carbon dioxide emissions by 15%. (Incidentally,
all our fleet vans run on LPG – another environmentally friendly
measure).
Installers, such us here at MJC Plumbing, follow official CORGI
guidelines to decide whether a installing condensing boiler is suitable
– there are still some exceptions (around 5%).
Condensing boilers all produce steam**. It’s not harmful,
but will cool into a liquid; around 0.5 to 1 litre an hour. You
can dispose of this in a number of ways: via sink waste, soil pipes
or an outside gulley. We will recommend which is best for you. We’ll
also help you decide if, and where, the flue ought to be situated.
** Don’t understand what is the matter here – don’t
they produce steam? If not, what happens? |
