Boost 5 hrs - Possibly the best feature of Green Gen2 When you choose the boost 5 hrs, on the first night the offpeak will come in for 5 hours. If your hot water reaches cut off temp before midday the designated allowance will reduce by 12.5% each night until it finds the perfect setting for your families needs. If the hot water system misses cut off that day due to cloudy weather or extra use then next time off peak is available it will heat until cut off temp is reached.
