With this prolonged spell of warm weather, the ground through which the mains water flows has warmed up considerably. I have noticed that the ‘cold water’ is now tepid and decided to check the temperature; our main is flowing in at ~26.5 degrees C. this morning. This may go some way to explain how our daily DHW energy requirement has dropped to ~ 2.3 kWh when normally in the summer, it would be ~3 - 3.5 kWh per day. (This is using the Sunamp Thermino Epv 210 and servicing the needs of two persons.)  Regards, Toodles.
