Keeping your boiler in top shape is crucial to its continued performance and efficiency. After all, the last thing you want is for it to malfunction all of a sudden, especially during the cold weather months. Understanding the most common issues surrounding this heating system helps you take the necessary steps to maintain or replace it before it breaks down.

Here, tankless cold climate water heater contractor McLay Services, Inc. discusses the reasons behind the most common boiler problems.

Thermostat malfunction. This might seem like a minor issue, but it can have major consequences for your boiler. Loose or disconnected electrical connections within the thermostat can prevent the heating system from turning on and off properly. This, in turn, leads to inconsistent temperature readings that affect the overall comfort of your living spaces.

Igniter or pilot light failure. Whether your boiler is powered by gas or oil, it relies on the pilot light to fire up the main burner. If it doesn’t stay lit or function properly when you need heating the most, your heating system will be rendered useless. Get in touch with your HVAC technician as soon as possible to have this critical component of your boiler inspected for any issues.

Limescale buildup. Mineral deposits inside your boiler, especially around the heat exchanger, will prevent it from performing efficiently. Unless addressed promptly, this accumulation can restrict the flow of water and even cause water to boil inside and turn to steam. Call your plumber promptly before this can lead to serious problems.

Water leaks. Leaks are quite common in a problematic boiler and are a sign of an issue inside the heating system. Heavy wear and tear and old age lead to loose joints and stress cracks. Some crucial components, including the pressure relief valve, may also start to malfunction. At the first sign of a leak, contact a boiler expert.
