Warm water on tap post soft

[Lightspeed]

we have just ripped out an over large insulated hot water cylinder, which I am keeping with the plan to reuse it as the reservoir of a thermo-syphoned solar water heater.

Rge collector will be like Mortblanc's frirnd's: Coiled garden hose mounted on stout roofing board and painted mat black. For improved efficiency, the board id backed with Kingspan type roofing insulation, and polycarbonate clear glaxing is mounted over the collector coil. The plan is for the collector(s) will be mounted at near-ground level, aligned for most reliable strong sun exposure.

Our objective for the system is for a low visual profile, non seasonal installation that will collect enough hot water for a few times each week throughout the warm side of the equinoxl

has anyone on here already done this?
