This heating key is specially optimized for venting radiators. It is perfect for precisely opening and closing the small vent valve on the side of radiators. This allows air trapped in the system to be released in a controlled manner until water follows.
It is the ideal tool when a heater no longer heats up properly or makes gurgling noises. By venting, the hot water is distributed evenly again, which noticeably saves energy and heating costs.
