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?

    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.

    There are some complications - especially where the ground is used to cool air in the summer - you get a lot of condensation in the pipe - so not only is some means of drainage required, but also some means of preventing mould growth - one way of doing that I gather is to use a pipe with a small amount of silver incorporated into the plastic.

    heat ex changers may be the safer way to avoid mould spores in the house air. of course if the duct you draw air from is shared with cables running warm, it may not be such a great idea in summer.
