That is, to make the pipe colder rather than hotter. You surround a hot water pipe with an ice pack. You put the TC mounted on the pipe ~20 cm downstream from the ice pack. You compare this TC to the water temperature. Is this a reasonable simulation? How far should the TC be from the ice pack, given the conductivity of copper? In my kitchen, you would look for a temperature difference between the pipe and fluid significantly greater than 1°C. Naturally, you would look for the 1°C difference again, before applying the ice pack. The ice pack is ~60°C colder than the pipe and water. - Jed
