Common Boiler Issues

Do you own a house? If so, there’s a high possibility that you’ve got a boiler. A boiler serves different purposes. Unfortunately, they also tend to malfunction for a range of reasons, just like any other equipment or appliance in your house.  

Having issues with your boiler can produce a nightmare and affect the overall comfort of your house. Today, we’re going to discuss some of the most common issues that your boiler may experience. If you encounter any of the issues mentioned below, make sure you hire a professional HVAC San Francisco technician to fix it right away.  

Blocked Pipes 

Oftentimes, the water inside the pipes of your boiler undergoes constant temperature changes. Because of this, it results in contraction and expansion. During the cold months, water inside the pipes might tend to cool and creates ice. This can clog the pipe. This stops the water flow and thus resulting in more issues.  

Low Water Pressure 

To guarantee a proper water flow in the pipework, the water pressure inside the boiler needs to be at an ideal level. It should also be regulated properly. Issues, where low or no water pressure is detected, are almost associated with malfunctioning valves or a current water leakage issue.  

Noisy Boilers 

This is perhaps one of the most common issues. This is particularly true for old boilers. Typically, they create gurgling, whistling, and rumbling sounds. You will hear this noise when the boiler is activated. Typically, the rumbling noise is caused by the buildup of sludge and lime scale on the heating element or heat exchanger.  

Leaking Pipes and Tanks 

If your boilers are leaking, it can result in a huge mess in your home. The common causes of pipe and boiler tank leakages include the boiler’s over-pressurization due to malfunctioning valves. Furthermore, weakened joints in the pipework might cause a minor increase in water pressure to burst the pipes.  

Failure to Heat Water 

Your boiler might fail to properly heat water. This is a popular issue that is associated commonly with a series of causes. A couple of the main reasons for failure in the boiler heater include damaged heating elements, problems with the thermostats, valve failure, damaged diaphragms, and much more.  

Boiler Not Powering Up 

If you’ve got a boiler that doesn’t power up, the first thing you’ve got to do is to examine the power supplies and other appliances in your house to see if they’re working. If other appliances are fine, inspect the fuse box to see if any switches have tripped or failed. If you still can’t find the reason, it’s ideal to hire a professional HVAC technician.  

Malfunctioning Pilot Light 

Outdated boilers might have a permanent pilot light that has to stay lit. You might have a malfunctioning thermocouple if the pilot light keeps on switching off. On the other hand, you might also have an accumulation of deposits.  

If you’re comfortable, you can try reigniting the pilot light on your own. However, you’ve got to ensure you follow the directions found in the manual of your boiler.
