Hot Water Radiator

The hot water radiator is copper pipe that is iteratively bent perpendicularly to create a heating surface of maximum area. The pipes follow the ridged lines. Through valves present at the bottom, water enters and exits. The pipes of copper are bent backward and forward ten to twenty times covering a maximum surface in order to give more heat. Large radiators have many such bents as they have a huge surface area that heats the full room in the building.
The hot water that is pumped inside the radiators from the main heating boiler passes through the copper pipes, heats the outer surface and ultimately warms the room. A screw valve located at the bottom of each radiator helps in temperature control.
