How to Bleed Air from a Baseboard Heating System

Baseboard heating systems are a common way to heat homes, but they can become inefficient if they become air-locked. When air gets trapped in the system, it prevents the water from flowing freely, which can lead to cold spots and uneven heating. Bleeding the air from the system is a simple process that can help to improve your home’s heating efficiency.

In this article, we will discuss what air-lock is, why it happens, and how to bleed air from a baseboard heating system. We will also provide tips for preventing air-locks in the future.

What is an Air-Lock?

An air-lock is a blockage that occurs when air gets trapped in a pipe or system. In a baseboard heating system, air-locks can occur in the supply lines, the return lines, or the radiator itself. When air gets trapped in the system, it prevents the water from flowing freely, which can lead to cold spots and uneven heating.

Why Does Air Get Trapped in a Baseboard Heating System?

There are a few reasons why air can get trapped in a baseboard heating system.

• The system is not properly installed. If the system is not installed correctly, there may be gaps or leaks that allow air to enter the system.
• The system is not properly maintained. If the system is not maintained regularly, the sediment and debris can build up and block the flow of water.
• The system is old. As a baseboard heating system ages, the seals and gaskets can wear out, which can allow air to leak into the system.

How to Bleed Air from a Baseboard Heating System

Bleeding air from a baseboard heating system is a simple process that can be done by following these steps:

1. Turn off the main water supply to the system.
2. Locate the air bleed valves on the baseboards. The air bleed valves are usually located at the top of the baseboards.
3. Open the air bleed valves by turning them counterclockwise.
4. Allow the water to flow out of the valves until it runs clear.
5. Close the air bleed valves by turning them clockwise.
6. Turn on the main water supply to the system.

Tips for Preventing Air-Locks in the Future

There are a few things you can do to prevent air-locks in your baseboard heating system.
