Would anyone like to chime in. I recently made an MOT spot welder for 18650 nickel strips. I can reliably weld 0.2mm nickel. Although I do need a slit if I’m doing nickel nickel (stacking for more amps)....
OK this is interesting, but also differs. If I have read correctly, you’re circulating the water in the system as a whole.
I’m also using a solar setup, but I’m using a serpentine coil running a separate coolant liquid. The coolant is used since winter goes from -10 to minimim -20 degrees celsius.
Hmm, the heater element being controller disregarding your will is a bit of a bummer.
Thanks for clarifying, so you are indeed circulating the water itself, it’s not a separate line used as a heater. In this case you really are at the mercy of either your pump, pipe length, ambient temperature, insulation and/or sun intensity.
Have you monitored the temperature at the panel on the roof itself? Also, what type of insulation are you running on those pipes?
