Air Lock In Baseboard Heating - Quick Fix


Baseboard water heating is one of the more used methods of home heating. While there are many benefits to this type of home heating, one of the drawbacks to it is that it has a tendency to air lock. This article will go through the basics of why this happens and what you can do to relieve this problem.

How baseboard water heating works

Baseboard heating works by simply piping hot water through pipes and into rooms. The hot water is stored in a boiler system, generally in the basement of the house. Then, once the water is heated, it is pumped through the piping system with a high-pressure pump, circulating the water through the system and back to the boiler to rewarm it. Once the water reaches the room, it goes through a pipe within a baseboard radiator, which radiates the heat out and into your room. These baseboard heating systems are particularly good because they are at the lowest point of the room, allowing the hot air to rise and warm the whole room relatively equally.

How to recognize the symptoms of an air lock

Airlocks can be tricky things. An airlock is essentially air that has gotten trapped in your pipelines.  If left untreated, you can actually end up breaking your pipes. On the mild side, an airlock can cause your system to heat unevenly, leaving you with warm and cold spots in the house.

An airlock is diagnosed mostly through sound. The most common complaint when there is an airlock is that someone hears a loud gurgling in the pipes or the sound of water rushing. If the pipe was filled with water, you wouldn't hear anything. But the air in your pipe allows the water to jiggle around, which lets you hear the gurgle.

How to quickly fix an air lock

Fixing this is a relatively simple procedure. On each of your baseboard heaters, there should be an air-bleed valve. Find this bleed valve and prepare to open it. Before doing so, however, place a bowl or tray underneath the valve. If there is air in this part of the system, when you open the valve it will rush out, relieving the issue. If the air is not in that part of the system, however, water will come out of the valve instead. This is where the tray comes in handy to stop you having a puddle. If air comes out at first, bleed the air out until water starts to come out, then shut your valve. If water comes out, move on to the next section of baseboard heating until you find the right one.

There you have it, a quick diagnosis of the symptoms and fixes for airlocks in baseboard heating. Of course, if you are not able to find your valves, simply do not feel comfortable, or this does not solve your problem, contact your local plumber to take a look at your system.
