Is it possible to control the heat booster supply by predictive piloting based on weather forecasts?

Edited

Yes, predictive control of the heat booster supply of a solar hot water tank is possible based on short-term weather forecasts. 

 

To do this, two conditions must be met:

  • To know precisely the daily consumption profile of domestic hot water (DHW), in order to generate a relevant piloting 

  • Calculate the amount of solar energy to come thanks to weather forecasts that are increasingly accurate and detailed.

 

Such solutions are currently under development.

 

How is the electric heating element for the water tank controlled? Via the controller? Is it necessary to have different modes of operation for peak/off-peak hours?
