Hi, is there any way I can boost the whole hot water feed. My pressure isn't great at the moment and I want to install a new shower. My cold water runs off the mains, but is there a pump I could use on the hot water only?
The normal shower pump have both hot and cold inlet/outlet. Could I possibly use one of these without using the other?
You can't fit a mixer shower by using mains water for the cold and water from a cylinder and header tank for the hot. Both feeds must be at equal pressure. If you don't have a combi, then the hot will come from the cylinder and the cold should come from the header tank and then fit a twin impeller pump.
