Shaun knows our climate. 1" irrigation coils that were used to aid in pool heating.
The pool has 2" circulation lines, so I ran 600' in two parallel 300' lengths of 1" dia black coils up on the roof. Gained quite a few degrees in the sunshine. Taking it all down as there are new shingles and eaves being installed before fall gets to far out of hand. Possibly will reinstall them at ground level, or maybe not at all.
And sure, it looks big, but don't forget, everything is metric up here so it's really quite small, har.
Flew the drone nice and slow to give the illusion of large tracts of land Bruce.
