The hot water to my bathroom, which goes the the sink and bath is supplied from a vented hot water cylinder. The cold water is supplied from the cold water tank. I already have a manual bath mixer shower, which I want to replace with a thermostatic bath mixer shower. I also want to increase the pressure of the shower. Can I simply install a twin impeller pump next the hot water cylinder and pump both the existing cold and hot water supply to the bathroom, ie the it would supply the sink, bath and WC as well as the shower. this would avoid any addtional pluming in the bathroom.
