Well it's simple: ALL
Good for my pump problem, I went to L.Merlin see Guinard pumps.
The Dorinox models did not really inspire confidence. So I fell back on a Kietis 4000 (660W) model from Guinard:
She seemed much stronger than the Dorinox (and as it will be quite solicitée ...)
It is mounted and is much quieter than the previous model (yet the Kietis has only 2 cells while the other had 4, probably a sign of the previous model's wear) and the buffer finally begins to heat up. (very slowly there was no sun since the repair)!
Good news regulation (a simple comparator: T ° high panel and T ° buffer) still works (after 20 ans for 20 years again!) ...
Next step: install a simple PM230 on the pump power supply history to see how much time it works per year and what consumption and cos phi she has ...
