  4. Hello, the valiant ecotec 824 is only capable of producing nine litres of hot water with a forty degree Celsius temperature rise per minute. Try measuring how much water you have coming out of a tap per minute with a weir cup or a plastic bucket. If you are only getting nine litres and its is still cold this would indicate a problem with either the plate to plate heat exchanger, the div valve or maybe a NTC sensor.
