I've got a loop of 475' of 1/2" (375 and about another hundred through three flat panel collectors,in parallel). There's about 14 elbows in the loop.
How big of a motor and what type would get the glycol flowing fast enough to warm my concrete floor without being too big or heavy or expensive or noisy or power-consuming?
I know my little Watts 500-800 1/25 hp. will hardly move the glycol at all.
Should I be considering a 3 speed pump to help adjust the temp of the glycol.(i.e. not letting it boil, or be to cold to do any good)
