Solar hot water is an obvious inclusion in our sustainable renovation. We install a 250 litre storage system on the garage roof next to our photovoltaic panels. The system is gas boosted to ensure that even on cold winter days we will have piping hot water 24/7. The system will further reduce electricity consumption in the house and save hundreds of dollars per year.
