From photos I have of when the project was in progress looks like the pipe work is in the ceilings, plastic, then runs down the walls are metal. Thos...
Thanks Toodles.Here's probably a stupid question. I notice: (Grant panel) LWT on Grant panel (I think this never shows .5C rounded to nearest 1)...

Thanks Derek, I’ll see if can find an hour to do this tomorrow. With the cycling it might be hard to get this however, perhaps recordings every 10 min...
