I’ve been looking at some of the data coming from my EcoDan system.
Something you can see here just looking at the tank temp maroon line at the top (chart is last 24 hours of time). At around midnight the HW temp falls to about 40 degrees which triggers the pump to bring it back up to 50. The temp then falls back across late night / early morning. Given I know no one is going to use the HW until 7am, is heating up at midnight a waste? It seems like that intially, but then you have to factor in that the tank temp would still fall further if not reheated at midnight.
Wondering if I could / should stop the HW heating up at midnight? (Of course if I had a nighttime elec tariff this could be a better strategy)
