If you have a well-fitted modern boiler, from a reputable company, it is less likely to cause issues, but of you have an older one or a cheaper one then you should pay attention to how it works and if the heating in your home is at a constant temperature. If you feel that it is a little colder than usual, then you may need to contact a boiler repair London service such as City Gas Services to help assess your problem. Here are some tips on what causes boiler problems, and how you can solve them.

Water leaking 

The thing with water leaking from your boiler is that at first these leaks can be very small. This problem can have a large number of causes, starting from loose connections inside the boiler, to broken parts. Water leaking leads to a loss of pressure in your boiler, so checking the temperature a good idea, and if you see that it drops below 0.5, or rises upper than 2, you should take into consideration calling a qualified heating engineer.


Pressure loss

A boiler works at its optimum level when the water pressure is constant. This issue appears when the expansion vessel has a problem or by water leaking. If you have a modern one, you can fix the pressure by adding some water in it, but if the problem is not solved by adding water then you should ask a trained engineer to help you with it.


Pilot light problems

If the pilot light is igniting, you should consult the manufacturer’s instructions. Sometimes, the main reason for this problem is a faulty thermocouple or damaged seals. If the problem is at your thermostat, try increasing the level of the boiler higher than the room temperature. The age of the thermostat can affect the accuracy of the temperature settings, and only a professional can clean it.


Noisy boiler

The causes of boiler noise can be divided into mechanical and chemical factors. Some of the mechanical factors are: the system design, the thermostat, some flow rate settings, or casting faults. In these cases, from incorrectly fitted pipes can result a system imbalance, or an incorrect flow rate can lead to kittling. Foaming and deposits are the chemical factors of boiler noises. The overheating in the foaming system can be produced by different things like suspended solids, contaminants or excessive residual flux. The deposits which cause boiler noise are corrosion debris or some thin lime scale deposits.


Other boiler problems

Sometimes, it happens to have a hot radiator at the bottom and cold at the top. Its causes may be due to rust in the pipes or to a buildup of air. Other times, the boiler just turns off, and its reasons are numerous, as air in the system, faulty pump, thermostat issues or low water pressure.


When having boiler issues check if the water, gas, oil or electricity feeds are switched on. If it’s cold inside, check if your condensate pipe is frozen, and reset your boiler by turning it off. Leave it for some minutes and turn it back again. Check the thermostat clocks from time to time, and adjust its settings  if the clocks go backwards and forwards. After trying these troubleshooting tips and the issues persist, you have to book a repair for your heating device.
