Modern boilers are considered to be resilient appliances and can provide heating and hot water to a home for years.
But, all boilers feature advanced technology and complicated processes, which means that a boiler can encounter problems from time to time. Here’s a list of the possible reasons why your boiler is broken or not functioning properly.
Broken Diaphragm Valve
A diaphragm valve is used to regulate or stop the flow of liquid or gas in the heating system. A broken diaphragm valve is likely to cause your heating system to stop working.
Kettling is what happens when lime scale deposits build up on the heat exchanger. When this occurs, you’ll hear a rumbling sound, hence the name. The solution for this problem is a simple one. Either hiring a boiler technician to replace the heat exchanger or fitting a magnetic and electrolytic scale inhibitor.
Airlocks in boiler systems are common and disrupt the flow of water within the internal plumbing system.
Dripping or leaking can also result in your boiler system not working properly, or breaking down altogether. This can be caused by a range of issues with the boiler system. An experienced boiler technician will be able to identify the problem by observing the location of the dripping.
Motorized Valve Failure
The motorized valve can get clogged, leading to the failure of the valve. This often times, results in the heating system switching on when not needed, or vice versa. The motorized valve can be easily replaced by an experienced boiler technician.
Condensate pipe freezing of the boiler occurs if the pipe of the boiler system is located outdoors. When this happens, it blocks the water inside as a consequence. Fortunately, most modern boiler systems have special triggers that switch off the boiler when the water reaches a certain point to avoid any further damage to the boiler.
As is the case with many older boiler systems, the thermostat is usually one of the first components of a home’s heating system to break down and malfunction. The older the thermostat gets the less efficient it becomes in giving a precise reading of the temperature of the boiler. This may lead to the boiler system turning the heating off or on by itself, due to the thermostat’s misreading of the temperature levels of the home. In this case, it would be best to invest in a new thermostat that’s preferably more energy efficient.
One of the main indicators of this problem is that the boiler starts making gurgling or banging noises, due to either a build-up of air in the system or low pressure.
The best way to keep your boiler from breaking down unexpectedly is to keep it properly maintained all through the year. You can do this by having your boiler system regularly checked and serviced by qualified boiler technicians. This will not only ensure that your boiler is able to perform at optimum levels at all times, but will also decrease the chances of it breaking down, which could possibly lead to more expense.
