Not a problem

Heating times 9 am - 3 pm is the best depending on conditions

Without getting into the technical side of things I put 500 mtrs of 16 mm tubing on the same type of roof

First i put down 4 X 6 mm Hardi plank sheets ( just screwed them into every 2 nd roof sheeting spot where they skipped for the roof sheet fixing )

Then I ( well started , the Cambodians finished ) , laid the coil in an oval shape covering a 4.8 m X 2.4 mt area

I use it for my wading pool & divert some of the water from the outlets to a secondary small pump ( pond pump with 5 mtr head ) - this seemed to work best ( maybe friction as even the pool pump alone only to coil wasn't that good )

It gets hot

Might not be steep enough...

 

 

That is a system designed for temperate zone areas in much higher latitudes than the tropical zone we are in. It is significantly over engineered (so ridiculously expensive) for Thailand, it may well be capable of producing water at over 90 degrees centigrade.
