Steam heating is one of the oldest heating technologies, and upright metal steam radiators positioned along walls in older homes are common. They can provide consistent, comfortable heat.
Steam radiators need some simple maintenance to work properly and efficiently. In addition, a radiator can wrap or create a groove in the floor. If that happens, the radiator may tilt, causing it to make loud banging noises. Plus, steam radiators on exterior walls can radiate some heat to the outdoors, and limit your ability to position furniture around the room.
