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
