Hi, just taken over a bungalow that has a conventional water cylinder downstairs, vented to a cold tank in the attic, and also it had a roof mounted solar hot water system with hot cylinders up there as well. A Drayton electric 3 way valve selects which cylinder system supplies the hot water for the whole house, selected by a switch in the downstairs cupboard.
Question is, can I fit a negative head shower pump in the attic after the three way valve to boost the downstairs shower, or is it essential to fit Surrey tank top outlets and take feed direct from top of cylinders???
If that is the case how will I select which tank to feed from, another Drayton 3 way valve maybe for shower pump hot feed only?
That valve would have to use same control as solar system.
Any advice appreciated
