Lesson 4
Radiators as Heat Exchangers
Work out what a radiator really gives out at your water temperatures, and why turning the flow down to 55°C roughly halves it.

Predict
Lena’s boiler sends water to her lounge radiator at 75°C and it comes back at 65°C. She turns the flow down so it goes out at 55°C and comes back at 45°C. The room is at 20°C. Compared with before, the radiator now gives out…
