50kVA diesel three phase generator supply.
Assume two male and two female showers, or are they all uni-sex these days?
I propose to suggest a large hot water tank for hot water storage, (thanks Simon Barker & Broadgage) then have three (say 1kW or 1.5kW or 2kW} immersion heaters if available, to heat the water. This will provide a balanced limited load to assist the generator in starting willingly. A single water thermostat controlling a three phase contactor to control the immersion heaters, to switch them all on or off at the same time. Perhaps a second maually re-settable "safety" hot water thermostat to cut off it the water becomes too hot.
The hot water storage tank can have a coil for thermal solar panel water heating.
So, what capacity of tank will I need?
What will the heat recovery time be?
What types of showers and shower pump(s)?
If available where can such an insulated tank be obtained?
What about hot water temperature safety at the shower heads?
Other?
