Heat up time is based on raising the auxillary volume from 15ºC to 60ºC using the lower 3kW
immersion heater.
Boost Volume = 57 Litres
Heating times using solar primary circuit will be variable as they will depend on the amount of
solar radiation, sunshine hours, collector panel type, size and orientation.
