During the summer it's great but as soon as the winter comes the water outside gets cold we have trouble, i have a tank in the loft for our condensing combi boiler, i tee'd of the mains supply to get to the shower. When we use the shower in the winter we have to have the dial right round to the highest hot setting to have a not very powerful shower.thank any idea Gary from Hornchurch Essex

are both the heating elements working fully do a ohms test on the elements to see if one is not performing fully.
you shouldn't need any electric shower on fully hot to use.
