System Goals
Exchange Solar heat to aquarium water.
Efficiency
Heat transfer is limited by the thermal conductivity of the pipe (PEH ~0.5 W/m K good for plastics).
Is high-pressure system ideal or is a low-pressure gravity system possible using black gutter(s) etc.?
Can water be mixed directly or is thermal mixing a bigger problem?
Can temperature be managed by pump control?
