Replace hot water cylinder

Current hot water cylinder about 100Litre. Need to replace to a larger cylinder to suit about 4 people. Wondering if it is possible to fit the cylinder in the ceiling space? Please quote ceiling installation (if possible) and straight replacing the cylinder where it is at the moment. The space for it at the moment is pretty tight and I was told that it can fit a 180L cylinder. And would like to install some sort of fan in the bathroom. Thank you.
