I bought a house with one of those expensive and "efficient" radiant cover heaters in the masters bedroom. It's electric. However, it is so loud when heating up (or cooling down) with metal expansion that it prevents us from sleeping. It's like someone is banging on the heater with a spoon every 2 seconds!

Is my heater garbage or it can be arranged? Any recommandations on that particular case?
Thank you very much.
