Unvented or pumped - which will give best shower?

[jimjam]

Hi All,

As per the topic title I'm trying to assess which will give the most powerful shower. An unvented system which would give mains pressure hot water or a standard gravity fed system with a seperate pump on the shower?

Assume that flow is sufficient (30litres per minute) and that pressure at the risgin main is good.

An un-vented cylinder assuming the mains can deliver.

Remember even quite pumps make a noise.
