Sample data 9:09 PM Hot water 65°C Start 5 min. MIN/MAX measuring Delta T (T1-T2) 9:15 PM Max 2.5, Min 1.6, T1-T2 1.0 Instantaneous reading T1 57.5°C, and T2 56.1°C, Delta T 1.4°C Ambient 22°C The point is: This T1-T2 MIN/MAX range over 5 min. sample did not change significantly when the T2 was by itself, or tied to the cold water pipe, or tied with cold water running through the cold water pipe. It did not change when the hot water temperature rose or fell. - Jed
