Re: low pressure, no electricity hot water

INSULATION – lots of it. Store hot water from previous day sun heating. Remember the more mass volume in round tanks the better.

Although it is a nuisance also consider using a rocket stove to preheat stored water to higher temps. Yes it does mean getting up earlier than the guests but isn’t that the nature of being in the service/hospitality business?

If you store the water in roof tanks a rocket stove on same level puts it outside the building thus less fire hazard and a chimney is no problem. Circulating water horizontalluy will be a thermo syphon so no pumping involved.
