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?
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.
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)....
