Comment on Why don’t we use radiators as heat sinks in the summer and pump cold water through them?

Energy transfer is proportional to the difference in temperature between the 2 things (delta T), their contact surface area (in this case the length of the radiator and the size of the fins), and time. If you want a room to change temperature quickly and with radiators that don’t take up an entire wall then you need the water temperature to be very different from the room temperature.
