Radiator
A heat exchanger that transfers heat from hot water or steam to room air through convection and radiation. Common types include cast iron, steel panel, and baseboard-style radiators. Typical connection sizes are 1/2" to 3/4" for residential hydronic systems. Radiators rely on proper air bleeding for efficient heat output.
