The boiler is quite an important appliance in your home during cold weather. You only understand its value when it stops working properly. Unfortunately, a boiler can stop working for quite a number of reasons.
Some of the issues will require you to hire a professional but there are smaller issues too. You can deal with the most common problems yourself. No, you do not even have to be a student of science to be able to do repair boiler.
All you need is the manual of the boiler with you and some knowledge. You also have to observe the boiler quite carefully.
Let’s check out how to repair the boiler when it comes to the most common problems.
- Bleeding the Radiators and the tank.
A boiler may show inconsistency in its performance if there is too much air in the radiator. Furthermore, it will do the same in case of too much water in the tank. This means that the pressure in the boiler is too high.
You can fix this by bleeding the tank or the radiator- whichever has the problem. Find out which radiator isn’t warm when the boiler is turned on. Then, after identifying it, turn the central heating system off.
Use the radiator key on the valve and turn it anti-clockwise to let the air out. Once you hear no hissing sound and possibly water coming out you can turn the valve clockwise and stop. This should fix the problem.
- Dealing with low pressure.
You can re-pressurize your boiler n one way. If you can’t then you have to take it to a professional. If the reading of the pressure gauge is below 1 then your boiler needs more pressure.
Usually, at the bottom of the boiler, you will find its filling loop. Shut the boiler down and keep the end of the hoses connected to the valves. Then, open the valves to let water in and fill up the boiler.
Once the pressure gauge reaches 1.5 then you can stop and switch the boiler on.
- Clean the pipes and seals.
A mentionable cause of boiler issues is corrosion and buildup. If you are facing leaks and overheating or loud sounds then buildup might be the cause. In this case, you will have to clean the inside of the pipes, valves, and seals. This will clear their path fixing the issue.
- Reset the Boiler.
This is worth a try just like you would with a computer. If you are not sure if something is wrong with the boiler then just find the reset button. Press it for ten seconds and the boiler will normally start functioning again. If it does not then there may be other problems.
- The Thermostat.
If the reading on the thermostat is not correct despite the boiler working just fine it is faulty. You may have to change the batteries in it or replace it completely.
If the boiler is not heating water then the issues may be deeper. Airlocks, broken diaphragms are not things you can fix by yourself. Therefore, you have to leave the rest of the repairs to the experts.
