A radiator is a heat exchanger that transfers thermal energy to warm a space. In HVAC systems, radiators typically distribute heat from a boiler or heat pump by circulating hot water or steam through the unit, which then radiates heat into the room.

Radiators in residential buildings provide steady heat in winter by circulating hot water from a central boiler.
Bleed radiators annually to remove trapped air and maintain efficient heating.
“Bleed radiators annually to remove trapped air and maintain efficient heating.”
Radiators were introduced in the mid-19th century and have evolved into modern, efficient designs.
Why is my radiator cold at the top?
Air is likely trapped and the radiator needs bleeding.
Can I install a radiator myself?
Installation should be handled by a professional to ensure proper sizing and safe connections.
Do radiators work with heat pumps?
Yes, but system design must account for lower water temperatures in heat pump systems.
