	The system has been losing pressure regularly, causing hot water to fail, and as part of the monitoring we have added a pressure sensor to the main system to investigate.		The system has been losing pressure regularly, causing hot water to fail, and as part of the monitoring we have added a pressure sensor to the main system to investigate.

			A Grundfos RPS sensor was used, providing both static pressure and temperature signals. It was fitted near the top of Thermal Store 1.

	As soon as data became available the reason became clear... the expansion vessel is not functioning, and pressures climb by around a bar during reheat cycles, then drop. On the first heat up following a top-up, water is discharged with nowhere else to go, and then when the store cools at all, pressure drop significantly.

			The following graph shows heat pump output temperature in orange and system pressure in blue.

			The ability to plot multiple historical metrics side by side is a great advantage in fault finding.
