Radiators Not Heating Up After Draining System. our central heating system needed a good clean, so we drained the system, cleaned, placed in the solution. A thermostatic radiator valve (trv) controls the flow of hot water to a radiator and occasionally these can get stuck, meaning they can't open to allow the hot water in. my problems started when i drained the system down to replace my faulty honeywell zone valve. whenever i drain a central heating system and refill it and a radiator is not heating up, it’s guaranteed to be because of an airlock in. if it is just one radiator not heating up, then a stuck thermostatic radiator valve could be the culprit. i have filled the system back up from the header tank in the loft and added some inhibitor, bled all the radiators from. i've recently drained the ch system so that i could replace a damaged rad valve upstairs. you might want to leave one rad alone as a heating load to prevent the boiler possibly activating any overheat. the pipes which feed these two radiators go straight up to the celling and are running through the floor upstairs back.
