Why Are Radiators Noisy?
The clanking or banging is a result of the pipes rubbing against surrounding surfaces as they contract and expand in response to heat changes. When they heat up, radiators are scorching hot to the touch. Most radiators include a top covering or a full-length metal radiator cover for safety. The cover can still heat up, but it also serves as a reminder that the unit underneath is hot. In most vintage homes and apartment buildings, the radiator is located near a window. Today, radiators are still admired by many for their vintage beauty and as a remnant of the past.
