In the spring we dug the water line deeper, motorized the pump, installed a new 2Kw Whirlwind (which is up to this day), purchased a 50-year-old Delco light plant as a back-up, moved the wood stove into the basement, installed a direct thermosyphon solar direct hot water (DHW) system (yes, in northern Wisconsin), planted a huge garden, and I went to town and got a job designing energy saving retrofits for seniors on SSI for a year.

Besides the pump, there are only six parts in the system: 1) a pressure gauge (0-60psi) will let you know the closed loop has not lost its charge of antifreeze; 2) a solar expansion tank allows the solar solution to expand as it heats; 3) a check valve above the tank to prevent thermosyphoning at night; 4) a pressure relief valve; 5) a hose valve at the lowest point for filling and draining; 6) a bypass valve around the check valve to allow the heat to thermosyphon back to the roof collector at night, to prevent the tank from overheating if you are away.
