Residential boilers are a great way to heat your home. However, as with any major appliance in your home, problems will occur over time and you will need to know how to properly troubleshoot those problems. Residential oil fired boilers will have different maintenance and troubleshooting needs than gas fired boilers in residential settings.
A fuel oil fired (or oil fired) system will require regular attention to the fuel filter and blower which can be higher maintenance than gas fired boilers. Residential boiler troubleshooting essentially comes down to understanding how your boiler system works and knowing the warning signs of when things are not operating properly. Knowing how residential boilers work can seem like an intimidating task to the uninitiated, especially if you are familiar with forced air heating systems. However, the basic principals are mostly the same but instead of warm air moving through your home, you have warm water moving through pipes.
While there are certainly more parts to a residential boiler when compared to a forced air furnace, that doesn’t necessarily make them that much more complicated. In fact, the majority of problems with most residential boiler systems can be traced to the expansion tank, the water circulator pumps or the thermostat and zone valves.
In fact, one of the most common problems with a residential boiler isn’t a part failure at all. If too much air builds up in your system the pipes will become noisy and inefficient. However, all boiler systems will have a bleeder (or pressure release) valve which can be opened to release excess air from your boiler system. Be sure when you open the release valve you wear protective gear to prevent injury. One popular brand that is durable is Carhartt clothing.
In the end, you do not need to be an expert when it comes to your residential boiler system. If you have problems that you do not understand or cannot fix yourself, call a local service technician to take a look at your system and get it running at peak efficiency.
