Homes with boiler heating systems in Centennial are less common than forced-air setups, but the ones that exist tend to be in older properties where the original hydronic system has been running for decades. Hot water boilers that have been maintained can last 25 to 30 years. Steam systems can last even longer. But age brings its own problems: zone valves fail, circulation pumps wear out, pressure relief valves start weeping, and thermocouple and control components degrade. WireNut’s technicians understand these systems and how to diagnose them correctly.

For homes where the boiler has reached the end of its useful life, our heating replacement team handles complete system evaluation and replacement options. For overall HVAC concerns beyond the boiler, our HVAC maintenance service covers the full system. See all Centennial HVAC services we offer.

• Boiler not heating diagnosed to find whether the cause is a pilot or ignition failure, a thermocouple issue, a gas valve problem, or a circulation failure.
• Zone valve repair and replacement for hydronic systems where one or more zones are not heating despite the boiler operating.
• Circulation pump service for systems where hot water is not moving through the distribution system effectively due to a pump failure or air lock.
• Pressure issues including low pressure causing the system to lock out and high pressure causing the relief valve to discharge.
• Boiler replacement for systems that have reached end of life or have experienced a failure that makes replacement the more cost-effective path.

Here are the boiler repair and service calls our Centennial technicians handle most often.

Why Is My Boiler Losing Pressure in My Centennial Home?

A hot water boiler that repeatedly loses pressure is losing water from the system somewhere. Common causes include a weeping pressure relief valve that is discharging small amounts of water, a leak at a fitting or zone valve in the distribution piping, a failing expansion tank that is no longer maintaining correct system pressure, or an internal boiler leak. A boiler that needs water added frequently is telling you there is a leak, and finding the source is the first step. WireNut can diagnose and repair pressure loss issues in Centennial boiler systems.

Low pressure itself causes the boiler to lock out on its low-pressure safety control. If your boiler is shutting off and showing a low-pressure fault, manually adding water to bring pressure back into the normal range will restore operation temporarily, but the underlying leak needs to be found and repaired to prevent the problem from recurring.

How Long Do Boilers Last in Centennial Homes?

A well-maintained hot water boiler can last 25 to 30 years. Steam boilers can last longer with proper maintenance. The most important factor in boiler longevity is annual service that includes checking and adjusting pressure settings, testing safety controls, inspecting the heat exchanger, and addressing small leaks before they become significant failures. Centennial homes with boilers that have been serviced regularly often have systems that are still performing well at 20 to 25 years.

When a boiler does reach the end of its useful life, replacement with a modern high-efficiency unit offers significant energy savings over older, lower-efficiency systems. WireNut can assess your boiler’s condition and give you an honest picture of where it stands in its service life.
