Supreme Solar Water Heater 300 L

The Supreme Solar Water Heater 300 L is a larger option that can accommodate the needs of families of 5-6 people. It has all the same features as the 200 L model, including a stainless steel inner tank, a powder-coated outer tank, and a 5-year warranty on the tank. The bigger size allows you to store more hot water, so you'll have a larger reserve for showers and baths. However, it will also be slightly more expensive than the 200 L model.
