Strange one today, storage heater was roasting hot at the top but cooler at the bottom. Tested all elements, was getting 23 ohms for each of them so elements are fine, but client complaining that it’s not as warm as it used to be. The charge control clicks on and off when turning, could it be that the charge controller isn’t working as it should and not letting it heat up enough? Fitted a few heaters but limited experience of fault finding on them any help would be appreciated
