How Do Boilers Work?

Boilers are known for their reliability and ability to maintain a steady, comfortable indoor temperature.

Fueled by natural gas or propane, they use a closed-loop system to heat and distribute water. The hot water moves through pipes to baseboards or radiators throughout a home.

Boiler Installation & Replacement

Boilers are a consistent heating source that is great for Northern Virginia homes. They typically last for 15 years before you need a heating replacement.

Benefits of upgrading to a new boiler include:

  • Enhanced energy efficiency: Modern boilers are designed to consume less energy, making them more energy- and cost-efficient.
  • Improved system performance: Newer boilers come with advanced features that improve the performance and functionality of your unit, resulting in better heating control and distribution.
  • Enhanced safety: Newer boiler models adhere to updated safety standards, offering improved safety for your home.

Trust Len The Plumber for a seamless installation process. We’ll answer all your questions and ensure your new boiler is installed according to manufacturer specifications.

Boiler Maintenance

Ensure optimal boiler performance and longevity with preventative tune-ups. Heating maintenance enhances the efficiency, reliability, and safety of your boiler.

Common boiler maintenance tasks include:

  • Checking for leaks: Addressing leaks promptly can prevent water damage and system inefficiencies.
  • Cleaning the burner and heat exchanger: Regular cleaning ensures optimal combustion and heat transfer.
  • Analyzing the flue: Adjustments may be needed to optimize fuel efficiency and minimize emissions.
  • Inspecting the pressure relief valve: This valve is crucial for releasing excess pressure and preventing damage to the boiler.
  • Bleeding radiators: If your system uses radiators, bleeding them periodically releases trapped air, improving water circulation and heat distribution.
  • Testing safety controls: We’ll verify the operation of safety controls, such as the pressure relief valve, high-limit control, and flame safeguard controls.
  • Checking thermostat calibration: We’ll ensure the thermostat is calibrated correctly to maintain accurate temperature control.
  • Inspecting the pilot light: If your boiler has a pilot light, we’ll ensure the flame is steady and blue.

Frequently Asked Questions

What’s the difference between a boiler and a furnace?

A boiler heats water that is then distributed through radiators or baseboards.

A furnace generates warm air, which is then circulated through air ducts.

What are boiler efficiency ratings?

AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a boiler converts energy into heat for your home.

For example, an AFUE of 90% indicates that 90% of the fuel’s energy warms your home, while the remaining 10% is lost through combustion.

  • Older, low-efficiency boilers have 56% to 70% AFUE.
  • Mid-efficiency boilers have 81% to 83% AFUE.
  • High-efficiency boilers have 90% to 98.5% AFUE.

What is boiler kettling, and how do I stop it?

Boiler kettling is the sound of whistling, popping, and bubbling sounds from an older boiler.

This problem often results from leaks, overheating, and limescale buildup inside the boiler.
