Hello everyone,
to save energy, I want to preferentially heat the whirlpool when the photovoltaic system is supplying power. This is no problem with a potential-free switchable socket, which I can control from my system. At the same time, I also want to prevent the temperature from dropping below 36 degrees if the photovoltaic system does not provide enough energy for an extended period. This could be done with a water temperature sensor that initiates a potential-free signal when the set temperature is undershot. The idea now is to use a socket with 2 potential-free switching contacts that supply power when either enough energy comes from the photovoltaic system or the water temperature falls below 36 degrees. Overheating is prevented by the built-in control of the whirlpool. The power rating of the whirlpool is a pleasingly low 1400W. I have not yet measured the heat loss overnight in summer.
With another potential-free contact, I switch on the heating element in the domestic hot water heat pump. This raises the temperature in the storage tank by up to 10°k to 63 °C (alternatively the heat pump with a lower maximum value). In combination, the whirlpool would have priority over the domestic hot water heat pump.
What do you think of the idea? Who knows a suitable socket? Who has a better idea?
