An installer should do a calculation to work out the water requirements for the property and the number of occupants.
Example - 3 bedrooms plus 1 = 4 times by 45(L) is 180L. So, if cylinder comes in 150L and 210L we would recommend 210L - round up. Better having more and not using it than not having enough.
(Number of bedrooms + 1 times by 45L = rough guide to what is needed). However installer must consider all water usage in property.
