  1. Another common reason for radiators to be cold is air getting trapped in it. Most radiators come with a small air release valves, usually on the site opposite from where the main valve is. They are easiest to operate with a simple, tiny, cheap specialized tool the size of a bike lock key — which you most likely don’t have, but a pair of needle-nose pliers will do in a pinch. Open the valve, and air comes out. Be careful, though: when all the air has been released, water starts coming out, and water that has been circulating in a hot water heating system for years is FILTHY. Have a rag handy to catch the spray.

  2. Before fiddling with your radiators, you really should consult with your landlord first (if you have one). An acquaintance of mine had tenants who broke his radiator and the tenants had to pay for the repairs. Had they asked him to fix it, he would have himself, and if that didn’t work, he would have called a company. It would not be fun to have to pay hundreds of euros to fix something if you break it, especially when it would be your landlord’s responsibility to fix it in the first place.
