WHAT ARE THE MOST COMMON PROBLEMS
WITH COMBINATION BOILERS?
 |
No hot water
- rubber diaphragms perished in
diverter valves. |
|
No heating -
pumps either seized or burned out. |
|
Due to complex electronics on most
combination boilers,
PCB (printed circuit boards) fail and need
replacing. |
|
Fans
and air pressure switches
can also fail causing malfunction on the boiler's
firing sequence. |
WHAT ARE THE MOST COMMON PROBLEMS
WITH CONVENTIONAL (SYSTEM) BOILERS?
|
Pumps seizing up in summer when
not used, synchron motor in 3 way valves
burning out. |
|
Air locks in open vented systems can cause loud banging
pipes and air building up in radiators. |
| Pilot lights can
extinguish on older boilers as most new one have electronic ignition
which unfortunately they operate from a PCB
which can malfunction too. |
WHY DO MY RADIATORS HAVE COLD AREAS?
|
If your radiator is cold at the top
and hot at the bottom, this generally indicates that air is trapped at
the top of your radiator. Bleeding the radiators to release the air is a
simple procedure, which may resolve this problem quickly. However, if this
problem persists, we recommend you have your central heating checked by
us. |
|
If your radiator is cold at the
bottom and hot on the top, this usually indicates sludge build up in
the bottom of the radiator. To remedy this problem we recommend you seek
professional advice to identify the cause of the sludge first. This problem is
generally resolved by power
flushing the system to eliminate unwanted debris. |
