Common Types Of Boilers Faults
Boiler systems usually experience issues
during autumn, when they are forced to work
harder after the more relaxed season of
summer.
To get the most out of a boiler it is advisable
to fire it up every so often during the summer.
This will lower the chances of the system
breaking down when turned on in the winter.
But, there is usually not much to be
concerned about, if an issue does come up.
Fortunately, most problems that relate to a
central heating system are easy or cheap to
fix. However, when something more serious
arises, it is best to contact a heating engineer
or plumbing mechanic to provide the most
effective and quickest solution to the problem.

The Thermostat Controls Stop Working
In some cases, the homeowner has forgotten
to switch on their thermostat. The
temperature should always be set between 17
to 20 degrees centigrade as this is
recommended as a good temperature range.
If the radiator fails to heat up, the next step is
to check the programmers to make sure the
HW (hot water) and CH (central heating)
setting is on.
From here, the next step involves checking
whether electricity is supplying the system.
This also includes checking on the heating
fuse as it might have blown. If this is not the
problem, there might be an issue with the
motorised diverter valve. This part controls
hot water flow. Turning it off and then turning
it back on again may solve this issue.

The Thermostat Controls Stop Working
Finally, if this does not solve the issue the
pump may have broken down. This is the
device that pumps the heated water from a
flow pipe so that it can flow into the radiators
and the taps.
Mechanical failure and blockage are two of
the most common problems with this part. If
the pump is clogged it will require an intensive
clean to get rid of the dirt that has
accumulated inside.
Trapped air can also cause the pump to stop
working. There is a very small nut that will
help to release any excess air. As soon as
any water starts to flow out while releasing
the trapped air, the nut can then be closed
again. From here, the device can be tested
again to determine whether it is working.

The Radiator Only Warms Up At The Bottom
This issue is actually common and is easy to
fix. The solution involves bleeding the
radiator. The pump needs to be switched off
to stop air from getting inside the system. Use
a bucket under the radiator.
On one side of the radiator on the top is a
brass square nut that can be opened with a
radiator key by turning the nut in an anti-
clockwise direction. This will allow any hot air
inside the radiator to escape. As this
happens, any dirty water will flow into the
bucket. These radiator keys are easy to find in
most hardware stores.
This tool is essential for bleeding a radiator.
After bleeding the radiator, the valve must be
closed properly to check that there are no
leaks.

Sludge In The Heating System
This commonly occurs due to a build-up of debris
inside the radiator. This build-up must be flushed
out, by taking the radiator off the wall and then
flushing it out with fast running water. If this step
does not solve the issue, the pump may be
broken, a pipe might be blocked, or the heating
system is poorly designed.

Strange Noises Coming From The Heating System
Kettling is the common name used for a
sound that a boiler makes. If the boiler starts
making this noise the first time that the pilot
light is ignited, it may be caused by trapped
air.
The excess air can be vented out of the air-
bleed screw. If this fails to solve the problem,
check whether enough water is reaching the
boiler tank.
These problems can also come about due to
a build-up of sludge. Flushing the system is
the best way to solve this problem. If the
system is pressurised, make sure the setting
is at the correct level

The Overflow Doesn't Stop
With a system or traditional boiler, the water
tank situated in the loft will feed water to the
heating system. If the ball-cock is jammed, it
will create an overflow problem. When it
comes to immersion tanks, only an expert
plumber should be handling these issues.

The Heating System Pressure Drops Dramatically
The pressure gauge needs to be checked
when dealing with this problem. There are
many reasons why this problem occurs from
excess air inside the system after bleeding
out the radiator to water leakages.
After a maintenance service, the system
needs to be topped up with water, if there is a
noticeable pressure drop.
Expert engineers who have extensive
experience installing central heating systems
in Lonon suggest using the filling loop to add
more water. For those that are not sure about
handling this task, it is always better to hire a
professional to successfully complete the job.

The Heating System Pressure Drops Dramatically
When central heating systems break
down due to a boiler defect, this can turn
into a very costly affair. Losing hot water
during the winter months is not a pleasant
experience. If you are faced with a
problem, contact our company at
Emergency Plumber, solve your problem
as fast as possible.
Central heating is one of the essential
parts of any home to keep the home
comfortable and warm, especially during
the coldest months of winter. Here is
more information explaining what costs
are included to install new central heating
and boiler systems in residential homes.
