A central gas heating system works by equally distributing heat through ducts that are connected to the vents, providing a centralized heating effect. Over time, faulty installation or general wear and tear can cause these heating systems to develop some problems. To make sure that your unit will continue proper functioning in the years to come, read on to learn about common problems so you can fix or avoid them.
The Equipment Fails to Start
This is the most common problem regarding central gas heating systems. According to experts and heating system manufacturers, this problem is caused by the malfunctioning of pilot lights. On the other hand, the failure of pilot lights to open could mean a timer failure on your system or the heater’s thermostat may have registered a temperature that is far below the required temperature to make the heater start.
Problems with the Pipe Lines
It is important to replace any damaged pipes in your central heating system. Do this by turning off the unit and checking along the pipe lines for possible damages. These water pipes get damaged because of poor insulation, so that freezing temperatures cause damage to them. This may cause a significant drop in the boiler pressure, which eventually leads to some leaks in your pipe line.
Noise Created by Radiators
There are two main reasons why your radiator may get noisy or make unusual sounds. First, if the radiator makes noises similar to knocking, it is possible that the pipes of the equipment might have caught trapped air. This can be easily fixed by performing a “bleed” or by opening the valve to make the trapped air come out of the pipes. Another cause for noisy radiators could be the insufficiency of water in your central gas system’s tank. You may have to perform frequent check ups to make sure the tank is full to prevent these unwanted and irritating noises.
Heat Distributed is not Equal
Again, there are two causes which lead to uneven heat distribution from your central gas heating system. First, this may be due to a sludge which may have formed below the heating unit. This can be fixed by flushing the sludge with water to let it out of the pipe. If the heat distributed is still not equal, then a poorly installed circulating pump or a pipe which is blocked might be causing the problem. In this regard, you will need the assistance of a professional to fix your problem.
Problems with the Boiler
A central gas heating system as we all know runs through boilers and heaters. When pressure levels of the boiler go down significantly, this could cause damage to your boiler. The cause of this pressure drop is due to water leaks which are small but were not given the proper attention. Also, another possible cause might be the removal of trapped air from the radiator. These small problems when not attended to could damage your unit over time. This can be fixed by manually adding some water in the filling loop of the boiler.
