Boiler breakdowns are normally expensive inconveniences, and by some sort of coincidences, most of them normally occur during winter when they are needed the most. In as much as there are certain boiler problems which can be addressed without the need to call boiler repair technicians, there are some that are extremely technical in nature, and which you will be compelled to call a qualified professional if you don’t want to risk the life of the boiler as well as yours. From drips and leaks to weird noises, boilers are always prone to all manner of issues, and here is a brief discussion to some of the most common ones-:
- No hot water or heat in the boiler
A number of things can be responsible for the lack of heat or hot water in the boiler with the usual culprits being failure of the motorized valves, low level of water, problems with the thermostat, and a broken diaphragm and airlocks. If the boiler is not working, then you should start by checking the thermostat or the boiler pressure. If you suspect that the problem has been occasioned by a broken diaphragm, then a replacement will be necessary and only qualified boiler repair technicians can do this. Be sure to call them in good time.
- Boiler leaking or dripping
For leak and water drips from the boiler, you need to determine the exact point where the leak or the drip is taking place. However, never attempt to fix the leak on your own. The likely causes of leaks and drips are broken internal components such as pressure and seal valves. If the leak is from the pressure valve, this is an indication that the boiler pressure is too high and reducing it will be highly recommended. Of course, you can’t do that on your own, and you will have to call qualified technicians to have a look at it.
- Strange gurgling, whistling or banging noises
Such strange noises are common occurrences in the boilers, but they should never be taken lightly. Sometimes they are due to low water pressure and at other times, they could be an indication of imminent pump failure, especially if you are using an older unit. Depending on the type of noise being produced, you should be able to tell the actual cause, but if you are unable to do this, then you should call the experts to have a look at it.
- Boiler losing pressure
If the boiler’s pressure gauge is below 1, then this is an indication of a problem with the pressure components. Either the pressure release valve needs to be replaced or there is water leak in the system. You should check the unit to see if you can notice visible leaks and locate them, but if that’s not possible, then the best thing to do would be to call your boiler repair technicians for the right fix.
- Boiler switching itself off
There could be several reasons for this, including a problem with the thermostat, poor water flow due to closed valves, low water pressure, or failure of the pump to circulate water in the entire system. Whatever the reason, you are highly advised to call a qualified technician to have a look at it.
