Dodge These Boiler Problems with Seasonal Maintenance

There are a wide variety of advantages to using a boiler to heat your home and keep warm through even the coldest of winters, and now is the perfect time to start thinking about maintenance for this system.

Boilers do need fewer repairs than other heating systems such as furnaces and heat pumps, since they require a small number of mechanical parts, however that does not make them immune to problems. Keep reading to learn about some of the more common issues that your boiler can run into without proper preventive maintenance.

Failed Circulator Pump

Despite the fact that your boiler has fewer mechanical components than a furnace or heat pump, a circulator pump is one its most important parts. With natural wear and tear over the years, this pump starts to decline. Its purpose is to move hot water from the tank to send through the pipes to terminal points within your home. So if it breaks, it would need prompt repairs or replacement.

Of course, preventive maintenance allows our technicians to take a look at this component and others to ensure it is functioning well. And if it’s not or it’s showing signs of wear, we can give you proper warning.

Expansion Tank Issue

Take note of what your boiler’s water tank looks like. You’ll notice a small cylindrical tank attached to a pressure gauge near the top. This component is your expansion tank, and its job is to maintain water pressure inside the boiler to help prevent the pressure from spiking.

However, if the membrane in the expansion tank breaks, your tank will be in danger of too-high water pressure, which can lead to a number of other problems.


Leaks are among the most common problems that boilers and water tanks run into. This may occur due to old pipes or even a poorly soldered connection, and lead to extensive water damage in your home. Plus it can lead to your boiler losing its heating capability. If you suspect you are experiencing a leak, be sure to call for immediate repairs.
