Bleeding a baseboard heater is the process of releasing trapped air from the system, which can improve the heater’s efficiency and performance. Air can become trapped in the system when the heater is first filled with water, or when air leaks into the system over time. If there is too much air in the system, the heater will not be able to circulate water properly, which will reduce its ability to heat the room. Bleeding the heater will release the trapped air and allow the water to circulate freely, restoring the heater’s efficiency.
There are a few different ways to bleed a baseboard heater. One common method is to use a radiator key. A radiator key is a small tool that can be inserted into the bleed valve on the heater. When the bleed valve is opened, air will escape from the system. Another method of bleeding a baseboard heater is to use a flat-head screwdriver. A flat-head screwdriver can be inserted into the bleed valve and turned to open it. Once the bleed valve is open, air will escape from the system.
