Experiences
„We've been using the heater for about a year with five Trina 450 W panels and were able to leave our oil heating almost completely off all summer.“
„On the second sunny day, my 180-litre hot water tank was already heated to 65 °C. Exactly as I wanted.“
„Our gas heating costs were high. Now, in the summer months, it's switched off completely in our two-person household.“
