Before doing any repairing job to any machine or system first you have to understand how it functions- its working principle and how its parts or components interdepend upon each other.

Basically a boiler is a closed vessel in which water or any other fluid is heated. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, boiler-based power generation, including central heating, cooking, and sanitation.

Boilers are fueled in a few different ways. You could have a boiler that uses natural gas or propane, which is known as a gas-fired boiler. Some houses have boilers that are fueled with fuel-oil, and are called oil-fired boilers.

If you are looking for a boiler that will need the least amount of maintenance, your best bet is to have a gas-fired boiler. Boilers that are oil-fired need a lot more work, and you will probably find yourself needing boiler repair more often than if you have a gas-fired boiler.

A broken-down boiler can really be a disaster unfolding especially during winter. Thus if you don’t have the necessary qualification to a boiler repair make sure you have contacts of a professional technician at hand.

Common Problems with Boilers

1)A lack of heat is the most common boiler problem. Here are the causes of this problem.

i)The thermostat isn’t working properly

ii)The boiler has low water levels

iii)The boiler is not getting any power

iv)The pilot light or electronic burner ignition is not working properly

The following problem can be resolved by doing the following:

i)If the water level is low add enough water so that the level is half full.

ii)If you have a natural gas boiler, check to make sure the control valve is closed.

iii)If the pilot light is out, simply re-start it.

iv)Try resetting the thermostat to see if the heat comes on. If the thermostat is the old analog type you may need to replace it.

v)Inspect to see if it is a blown fuse, if so you can replace it yourself.

vi)If there is no pilot light, you will have to check the electronic ignition system.

vii)Make sure the thermostat is in heat mode and is set to the right temperature.

2)For the case of fuel fired boiler another problem that is experienced is a yellow or sooty flame instead of being blue in color in the combustion chamber.

3)Sudden dropping or rising of the pressure or if it remains too high for prolonged periods of time. This could be another clear indicator of a problem with your boiler.

4)Carbon monoxide poisoning resulting due to incomplete fuel combustion.

5)Fuel leakages. This results to energy wastage and more cost expenditures.

It is usually no problem to fix the simple problems on your own. When you have other issues that you can’t fix yourself, it is best to call in a professional in boiler repair.
