How do Boilers Work?

Boilers are among the oldest home heating solutions. Safe, reliable, and energy-efficient, they’re the heart and soul of your radiant heating system, and many combination boilers are also configured to provide hot water for cooking, cleaning, bathing, and other needs.

They’re the closed, steel pressure vessels that are designed to provide the hot water for your hydronic heating system. They can be fueled by gas (natural or propane), electricity, and in some instances, coal. Steam boilers are designed to convert water to steam, while hot water boilers stop the heating just before the water boils. If you have a steam model, it will transfer heat through the radiator, while a hot water version will transfer it via boiler tubes. 

This process is energy-efficient, ensures even heat distribution, and can improve indoor air quality. Moreover, boilers are among the longest-lasting home heating systems, with many lasting 30+ years, and require minimal maintenance and repairs.  

Boiler Installation & Replacement

A properly installed and maintained system can last 30+ years. That’s why we take great care to ensure every detail of the installation process is thoroughly addressed and accounted for. Our technicians will help you select the optimal size for your needs and will prepare the installation site to accept your new boiler. In most cases, the installation process takes around half a day to complete. Installation time depends on installation requirements, any special system needs, the complexity of the system, and other factors that we’ll examine when providing you with an estimated timeline. 

Our technicians will install your boiler, calibrate the unit, and test the system to ensure everything is working properly. We can also help you determine whether it’s time to replace your aging unit with a newer, more energy-efficient system. Common signs you need a replacement include inconsistent/uneven heating, yellow pilot lights, rust/corrosion, and increasingly frequent and/or costly repairs. 

We offer free estimates and financing options so you can secure the boiler you need right away without the risk of sudden failure or potentially catastrophic malfunction. 

Same-Day Boiler Repairs

We offer 24/7 emergency service and can respond to and resolve any problem with your system. Prompt boiler repairs are essential for ensuring your comfort and safety and we recommend scheduling service at the first sign of trouble.

Common indicators that repairs are required include rust-colored water, yellow pilot lights, carbon monoxide alarms, leaks, low water pressure, inconsistent heating, and odd sounds during operation.

Trusted Boiler Maintenance

Staying current on maintenance is essential for preserving the energy efficiency, safety, and longevity of your boiler. Our maintenance services are customized to meet the needs of your specific system. We service all brands and will thoroughly inspect, test, clean, and calibrate your unit to deliver optimal performance. 

Common maintenance tasks our technicians perform include checking condensate temperature and water pH levels, checking the pilot light assembly, testing the low water cut-off valve, testing safety valves, inspecting hydronic piping, checking flue gas vents for leakage, calibrating controls, and more. In most cases, these tasks take one to two hours to complete.
