hot water and showers for campers

Introduction

  • whilst commercial caravan parks and some National Park camp grounds do offer hot water and hot showers, most camp grounds do not offer this and for those who are camping near their vehicles for more than a few days in the colder areas of Australia, a portable hot water system and shower may be desirable
  • the systems with built-in water heaters are very convenient but come at a not so insignificant size and weight which may just be too much for those in a car only.
  • NB. 1kg LPG propane provides 49MJ thus for most of these hot water burners, this equates to just under 2hrs of max. heat output per kg of LPG
  • this is to outline the various options and pros and cons of each

Portable gas hot water systems

  • these require propane gas to heat the water and depending upon the model, it may use cannister propane and/or connection to propane bottles
  • they generally include an automatic piezo burner starter which allows it to start as soon as you turn the pump on and you can generally select the output temperature
  • if not connected to a water mains (some will connect), you will need a 12V power supply and 12V water pump
  • water pump rates may vary from 2L/min to 8L/min depending upon model
  • others will require submersing the pump at the end of a supplied hose into a water container
  • most have shower heads which incorporate an on/off switch

    • tub can be emptied via drain hole or by turning on the pump and directing it outside
    • If the water does become too dirty or soapy, it can be drained and replaced, mid-shower, to rinse and continue showering. It is recommended to run fresh, non-soapy water, through the pump after each shower to avoid shortening the life of the pump.
