Use a radiator key, 1/4-in. 12-point socket, or a flat screwdriver (depending on your valve type) and slowly turn the valve counterclockwise until water starts dripping out. This will release trapped air and let hot water into the cold fins. While you’re at it, you should repeat the process with your other radiators.


If only some of your hot water radiators, hot water heating convector units, or hot water baseboard heating sections are not getting hot and the radiator valve is open, see AIRBOUND HEAT SYSTEM REPAIR by WATER FEED VALVE (hot water heat) or if a steam radiator valve is open but the radiator is still cold, the steam vent may not be working.

Hot-water radiators are one of the most common heat distribution systems in newer homes, second only to forced-air systems. They are typically a baseboard-type radiator or an upright design that resembles steam radiators. The most common problem in hot-water systems is unwanted air in the system.


The valve gradually closes as the temperature of the surrounding area increases, limiting the amount of hot water entering the radiator. The replacement of a manual heating control with a Thermostatic Radiator Valve has been estimated to save at least 280 kilograms of CO2 per year.
