If the sun is not shining, it is night time, or it is just plain cold AND you still want to take a warm shower, this might be for you.  These water heaters are relatively inexpensive costing around $125.  We have tested these with Road Shower 4, and they work well.  They do take some time to set up and space in your vehicle.  If you buy it from Amazon and you don’t like it, you can send it right back.

The Eccotemp L5 Portable Tankless Water Heater is the original and best-selling portable water heater on the market today. You get instant, endless hot water wherever you are. The Eccotemp L5 Portable Tankless Water Heater is perfect for campsites, cabins or simply around the house. Wash your car, wash your boat, take a hot shower, or even wash your horse. You can add the Eccotemp L5 Portable Water Heater to a pressure washer for an even better cleaning. This model includes an electronic ignition powered by 2 “D” cell batteries making it great for off grid or other areas where electricity is not readily available. The ideal operating range for the Eccotemp L5 Portable Tankless Water Heater is 20~80 PSI.

Since the Road Shower 4 will pressurize to 65 PSI and will usually have more than 20 PSI, it works well with the Eccotemp.  We have tested this unit.  It is about the size of a small brief case.  It is a little large, but can fit in most SUV’s or vans that are equipped with camping gear.  It needs propane. For us, a large 40 lb propane tank is too big to carry in our vehicle. So we use a small green propane bottle that we carry for our stove.  See adapter below.

To use it, hang it vertically from your cross bars or roof rack.   Connect your Road Shower hose to the inlet.  Connect the included shower sprayer and hose to the outlet. Connect your propane tank to the propane inlet using included hoses and adapters.  Insert 2 D-cell batteries. Turn the water on. Turn the burner knob and water knob to Max.  Press the on/off button to on.  You should hear a clicking sound that means the gas has ignited.  The water will be warm instantly.  If you have some sun and the water starts off a little warmer than the water can get hotter from the unit.  If the water is not quite hot enough, turn down the water flow. The slower the flow the hotter the water gets.

I recommend buying one of these adapters so you can use your small green bottle propane tanks meant for your stove.  You can get around 4 showers from one of these small tanks. Cost $9.

These are nice for when it is cold and/or you are in a campground and need privacy.  Cost around $32 on Amazon. They fold into a circle. Once you get the hang of it, they can be set up in about 1 minute, and taken down in 1 minute.
