The radiator heating and cooling system’s simple heat exchanger absorbs the heat energy from the air during the day and gives that heat back to the air at night. To put it this way, whenever the water is cooler then the air it cools and when it’s warmer it heats.
The radiator worked in a very simple but profound way.
Materials Needed for an Radiator Heating and Cooling System
In the picture is the radiator heating and cooling system in action. The red circles are marking the same point. Note, the filter is somehow upside down, it just happened that way :). We usually had the radiator running from midday when the greenhouse warmed up, until early morning when the water cooled down.
Enjoyed the project?
