Central Heating Systems
|
It is important
when choosing the type of boiler to be installed that you choose
the correct one. This section briefly outline the advantages and
disadvantages of common heating systems |
|
Back Boilers
This was a very
common way of providing heating and hot water. With a boiler
being situated behind a gas fire and using the existing chimney
as part of the flue. Using just gravity to heat the water and a
circulation pump to heat the radiators Probably one of the most
reliable boilers, however, not very efficient! Not the quickest
way of providing heating and hot water but these boilers
generally last for over 20 years
Conventional
Boilers
A boiler normally
mounted on the wall working very much the same as a back
boiler. However, in newer installations a valve was used
to mean that you could use your heating and hot water
independently. Still
extremely reliable but if you require regular amounts of hot
water not the best choice as once the cylinder is empty you have
to wait for it to heat up again. (In older tanks about an hour
but new ones approximately 25 minutes).
Combination (Combi)
Boilers
Just like its name
these boilers combine heating and hot water all in one. No tanks
and instantaneous hot water. This type of boiler will provide
bath after bath full of hot water but it is important to
remember that in the summer when your heating is off there may
be a short delay in getting hot water to a tap as the boiler has
to heat up before the water can. Early Combi boilers were not
very reliable but as with everything the newer one are very
good |

Warm Air Heating
This type of
heating is rarely installed now as the efficiency and
performance is not as good as a wet central heating system. The principal behind it is that cool air is
drawn into the appliance and the heated and blown out with a
fan. They normally have a separate appliance within them to heat
hot water with a similar method to a back boiler.
From April 2005
all installations will have to be condensing, with very few
exceptions. Click here for more

Boiler/Radiator size
| It is important
that the size of boiler and radiators are correct for the job
they are doing. There are methods for calculating this However
it is not ok to just add on radiator if you have an extension as
the boiler may not be “man” enough to cope with the extra output
required. |
