Many thanks 'artel' and 'marg6' for the reply in connection with my previous post. It makes sense what you both say but when the hot water is flowing through the shower head, there may be more cold water available from an onbard tank compared to an exterior water barrel but surely when the hot water tank is being replenished by cold water the hot water temperature slowly drops so it still only allows the same time showering whether it be one exterior water barrel or connected to a cold water mains supply.
Just trying to work this out to see if there is any benefit of having an onboard water tank because in respect of the above and having another tank to sterilise I can't really see much benefit of having one which is basically what the OP was asking.

I doubt if the water heater has the ability to heat that amount of water in such a short time. The main advantage as I see it is that with the two containers you have the ability to switch to the full one thus ensuring you have a shower without running out of water. Not necessarily a longer shower but a less inconvenienced one. As I said in my first post I find an onboard tank handy but it wouldn't be a deal breaker for me personally.
