Radiator
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.

FAQ
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.
