It's been lightly raining here all day today. Just checked my main inverter and it's produced a whopping 2.65 KWh for the day. On a clear day this time of year I'd expect to see a tad over 30 Kwh. That's what you have to look out for as I'm sure you well know. Some time back a mates brother worked for Dux. They were looking to take the water up to about 90oC. The reason was having the water hotter meant the tanks effectively were larger while actually being smaller to fit in apartments and the like without taking as much space. When used with the mixing valves there was effectively more " Useable" hot water. I don't know if they ever went with that or it got dropped.
