Campsite Showers Water Heating. For Chris P.

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?

  • So Zoom, there is no one fits all answer. You can only try judging the likely usage for say 90%+ of the time to start to compare. Then try the different options either on their own or in combination and then judge against cost and efficiency. Like you said the customer has jumped the gun and bought a generator, was this wise. Given that he has then can the immersion heater be used or tweaked for a realistic outcome? Is propane viable? then all the water/gas bye laws and good practice not to mention Sam & Elahi considerations etc etc .

    Bet you wished you never got involved

  • Do you know ebee, I am getting to the stage where I am about to walk away. There is no way I would ever consider connecting up the dilapidated shower block. It is currently a run down death trap.

  • Well Zoom you can hold yer head up that you tried to solve your customers problems rather than just give standard rapid options and opinions and then scarper like many would have done in short time.
