Campsite Showers Water Heating. For Chris P.

Zoomup

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?

    It seems like a ridiculous idea to me.

    My starting point would be to consider a solar thermal heating system.

    A few years back on a campsite in Spain I noticed a small hill mound had been built to lay a hosepipe type thingy at say 45 degrees from flat , the hose was as big as a fireman`s hose and i assumed they trickled water thru it in the sunshine to heat it up. crude but maybe it worked some

    I watched one of the Grand Designs TV shows, I cannot remember where it was, I think it was Australia, the house had a very long driveway and the services had to be dug in alongside it, so they buried a 100 mm plastic pipe in the same trench.

    So, there's several hundred metres of buried pipe and the air for the ventilation system is brought into the house through it and arrives at ground temperature, which means it is cooled in the summer and warmed in the winter saving on the cost of running the air conditioning that provides cooling and heating.

    So simple.

    That does indeed work. Even my small diameter garden hose gets the internal water very hot if left in the sun for an hour or two.

    At other than our recent weather we a probably a good deal cooler than Spain (or parts of it) but yes I can see how it works here too, every little helps. the Spanish one I saw was black too. 

    Well maybe a mixture of all these things might make a considerable difference in these times of high fuel bills
