Hi every one. i got bit problem with my Ecotech 824, When i open a hot water tap half way water is hot but when i open the tap full then water is just warm or cold. Central heating working fine. any help Please.
Has the dial on the boiler for hot water been turned down? http://www.vaillantspareparts.co.uk/Vaillant ecoTEC plus 824 user manual.pdf
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.
