My hot water supply from our Altherma unit is fine but our shower is almost cold.
Is it possible that the filter on the hot water inlet he's become blocked - they do recommend cleaning every 12 months and our has been there for five years.
I have found an instruction to do this HERE but cannot work out how the "Filter blanking cap" comes off?
Many thanks in advance
