If you put dry clothes over a radiator (or leave them on after they've dried), does it reduce the heat given out by the radiator? And if so where does that heat energy go? Told you it was random
heat energy is partially stored in the washing and the rest is lost thru convection to the colder areas of the room.
the amount of heat lost through convecton is also directly linked to whether you used powder or liquitabs to do your washing
I'm afraid Dek isn't quite right since the excess heat energy isn't stored in the clothes. It's true that the room is colder however. If you put clothes on a radiator you're essentially insulating your homes heating system. Less heat escapes into the room so the water in the radiator cools less and travels back to the boiler at a warmer temperature. The boiler then doesn't need to work as hard to warm the water up to the initial temperature. That's where the energy saving is.
