My husband has recently installed a new 8.5 kw electric shower (shower force). we previously had a 8.5 kw shower - gainsborough, i think.
we have a worcester combi boiler.
the shower is plumbed in correctly as there is water running from it, the standby light comes on so there is electicity going to it, however when on the water remains cold. no hot water at all.
Any ideas what the problem might be. Any advice would be really appreciated.[/b]
