1,2,3 or 4 bar

WATTY · 19 Nov 2006

I want to fit a twin impellor pump. There is 1 bathroom with overhead gravity shower over bath (not very powerful), 1 wet room with gravity fed shower and 1 shower room with gravity fed steam box and hand basin no toilet. Should the twin impellor pump be negative head? What is benefit? How to calculate correct bar needed? How to calculate maximum hot water usage?

When all 3 bathrooms in use, will hot water cylinder be able to cope with delivering hot water to all? What is the minimum capacity needed for cylinder?

Thanks
