Hey again all I meant to upload these earlier but had problems doing it. a mate lent me his infrared camera and I was able to take pics of the flooring, even when the boards and carpet are in place it lets you see where hot pipes are. pretty useless when trying to find cold ones of course! The first one shows when I ran the hot water. the second one shows the odd amount of heat i am getting from next door (terrace), this was taken about 6 hours after all hot water and heating was off. the last one just shows the rad pipes doing there thing the last one shows up the joists in the ceiling of the first floor, i think it would only work here as its colder in the loft.
