I thought I’d try some of what we’ll be doing at St Columba’s, but from the relative comfort of my own home – and potentially answering some questions at the same time. Here’s the set-up.
Question one: How much does the taping affect the readings of waterproof DS18’s on the (metal) surface of radiators? Of course we want maximal contact, metal on metal – but the sensor is round, and the radiator is flat. I’ve insulated one sensor with some curtain blackout lining, which is known as a reasonable thermal insulator. The question is whether it reads higher than the sensor next to it at peak, and how much it slows down the sensor response.
Question two: Is the lounge radiator behaving as expected? The work room is fine; the radiator is probably a bit bigger for the space, and it doesn’t have a big bay window or as big a fireplace, but still, it doesn’t seem right. I say “work room”, but it’s really just the room where we do just about everything, because it’s warm. Our demonstration of the principle of adaptive thermal comfort would be complete if we just moved some comfortable chairs into the work room and were done with it. Alas, they won’t fit through the door, and the one we bought from Lewis’ mysteriously vanished from the van on delivery day.
No answers yet, by the way. We’re waiting for the heating to go on and off again. There’s also the question of how to tape so that the sensors reliably stay on warm metal, at least for me – but I know Iain already has that one sorted.
