The Pros and Cons of Combi Boilers
Today’s modern Combi boilers are probably the most most popular kind of new boilers being fitted today
Combination boilers
or "combi boilers" have
become more and more
popular in the UK over the
past few years
with over 70% of homes
choosing to install a combi
boiler, over regular hot
water or system boilers.
What is
a Combi Boiler?
Combi boilers are essentially a high
efficiency water heater and central
heating unit,
which means that they can heat
your home and provide hot water
without the need for a separate
water tank.
They tend to be more compact than
other central heating systems, as they
combine these two household
functions into one appliance
(hence the name "combi boiler").
Who Should
Consider
a Combi Boiler?
Due to their small size and ability to heat
water on demand, combi boilers are most
suited to homes with limited space,
or for couples or small families.
It is possible to purchase an oil-fired
combi boiler, however,
gas and LPG models are more common.
The Benefits
of a Combi Boiler
There are a number of great features
hat have made combi boilers the most
popular boiler type across the UK.
In general, combi boilers are:
More Efficient
Combi boilers are highly efficient when
compared to older boiler models. In fact,
replacing your boiler with a newer combi
boiler could help youto save up to £600 a
year on your heating bills.
Cheaper
Combi boilers are far less complex than
traditional heating systems, which means
that installations tend to be cheaper.
Faster
With no water tank to heat up, combi
boilers can provide an unlimited supply
of hot water on demand. No waiting time!
More Compact
No need for a separate tanks in the airing
cupboard or loft, combi boiler systems
take up much less space than
conventional heating systems.
with no risk of freezing pipes
Showering
High pressure showers without the need
for mechanical power showers.
Install anywhere
Because of the huge number flueing
options Combis can be sited almost
anywhere in the house,
i.e. loft, airing cupboard, garage etc.
Less Likely to Suffer from
Pressure Issues
Combi boiler systems do not tend to suffer
from air locks or low pressure, as the hot
water is taken directly from the mains.
The Disadvantages
of a Combi Boiler
Despite the popularity of combi boilers,
there are several issues that you should
bear in mind when considering replacing
your boiler.
Dependant on Mains
Pressure
To ensure that your combi boiler is
working properly, you need good
mains pressure.
Limited Use
With most combi boilers it is not possible
to run more than one shower or bath at a
time, or to turn on the hot tap while
showering. This may be an issue if you
live in a large house with a number of
bathrooms and en suites, or with lots
of people.
No Immersion Heater
As there is no water tank, if your combi
boiler breaks down then you will be left
without hot water as well as central
heating
(unless you install an electric shower).
No Power Shower
While a Combi will provide a high
pressure Shower commensurate
with your water pressure, existing
Power Showers are unlikely to be
compatible with a Combi Boiler
