If anyone reading this has the above installation would they please post the present collector temperature or at anytime between say 2000 hrs and midnight, any night will do. Thanks.
I'm not at home atm but I reckon it was approx mid 20s as far as I remember
only seen this this morning 30 Chinese tubes into 200l temp at 8.45 pm top of cylinder 59* bottom 58* collector on roof 48* cloudy all day
So would say 24C be fairly typical around midnight?
mine was about that this morning raining hard here
