We have a newly installed seperate shower cubicle with a new (grohe) thermostatic mixer shower installed but have found that the shower is ice cold. We have a worcester combi boiler - less than 2 years old. Whatever we do to it, the is no sign of any draw of hot water and no change in the temp from ice cold.
Our cold water pressure is very high, the hot obviously not so high. We have a basic mixer shower head on the bath and that functions fine, quite good pressure at an appropriate shower temperature. The bathroom was installed by the builder, I don't think a plumber was involved (tho I could be wrong about that).
We have just had our bathroom overhauled (converted from toilet / bathroom to one larger room) in our small 3 bed semi. Previously we had a cheap electric shower over the bath which only took a cold water feed.
What could be wrong? Is it possible that it has been connected to two cold feeds? Is there any way to verify this? Is there a more likely alternative?
I am quite distraught at the possability of having to (or getting someone else to) tear the shower / tiles etc out :(
