Combi,
or combination boilers to give them their full name, are often an
excellent solution to the demands of a small or medium sized central
heating system or property. The name combi, or combination boiler, comes
from the fact that the appliance combines both the production of domestic
hot water and central heating in a single unit. This has many benefits,
particularly where space is at a premium. Space is saved because the combi
boiler effectively replaces the traditional boiler, hot water cylinder,
cold water tank, feed and expansion cistern, pump and control valves. Many
modern combi boilers will fit within a kitchen cabinet, and all modern
combies have comprehensive and flexible flue systems to allow the boiler
to be fitted away from external walls. Often we flue the boiler vertically
through the roof.
Domestic
hot water supply from a combination boiler is very convenient, because the
water is heated instantaneously, on demand. This means that water is only
heated when required, and there is never a tank of water heated, but not
used, as in more traditional hot water systems. Because of the immediate
nature of the hot water production, combi boilers are ideal in situations
where hot water may only be needed intermittently, or at odd hours of the
day and night, or possibly in properties which are not occupied all the
time, for example holiday homes. Most combies provide a similar amount of
heat output for central heating, usually between 24 and 30 kilowatts, but
vary greatly in their heat output for heating hot water. As a general
rule, the greater the heat output of the boiler for hot water, the higher
the flow rate of hot water. The larger wall hung combi boilers will give
in the region of 16 litres a minute of hot water, this will easily supply
two good showers. It is important though that the incoming cold water
mains supply can provide sufficient pressure and flow for the boiler.
As most
combi boilers will give an output of between 24 and 30 kilowatts for
central heating, they will heat most average sized domestic properties.
This could be as big as a five bedroom detached home, depending upon the
overall size of the building, and as many as 20 radiators, again depending
upon the size of the radiators. If you are in any doubt about the
ability of a boiler to heat your home, or the size of boiler you require,
please contact us. We would be delighted to help with technical advice, or
