I have a direct unvented water cylinder and recently needed a new element due to horrific limescale, I have a scale manager fitted and the suppliers tell me that if it wasn't doing it's job correctly the 2 tubes either side of the element (which I assume to be thermostat housings) would also be scaled. The logic here eludes me, I would be grateful if someone could explain if they would be scaled or not. I seem to be unable to attach a picture of the element, Many thanks
