How do Radiators work?
  • The heat source heats up the water in the boiler.
  • From there, the water travels to the radiators and transfers its heat to the radiator material, which is usually metal, a good conductor of heat.
  • The radiator then transfers its heat to the air, and that’s where convection comes into play. Thermal convection is based on the natural law that hot air rises and cold air drops.
  • As the radiator warms the air around it, that warmed air rises and flows into the room.
  • At the same time, the cold room air drops to the floor and is drawn toward the bottom of the radiator, where it becomes heated.
  • This hot-and-cold rotation naturally heats the room without the need for circulation fans or other mechanical means.
  • All standard hot water radiators have an inflow pipe and an outflow pipe, and many have some kind of temperature control for adjusting the flow of hot water through the radiator and thus the heat it puts out.
  • Radiators require a flow temperature of around 80°C flow and 70°C return.
  • Feel comfort by controlling the temperature of each radiator with a Thermostatic Head.
