Solar heater location and pump question

[pettinej]

Yes I had thought of painting as well.

My main concern is the pump. Will I be putting a strain on it or should I purchase a bigger one. (more HP)

"Strain" is not really an issue with a pump. As long as it has enough head to initial get water flowing through the panels you really should not have a problem. I would not pre-buy a bigger pump. Try the one you have and you can always upgrade it if need be. To install a bigger pump if not needed will just cost you money for a pump and higher electric bills.

Thank you. I appreciate the quick response.
