Best Camper Hot Water Heaters: Quick List

A camper hot water heater is a great luxury to have. While not a necessity, a camper water heater for a shower and sink does provide numerous benefits for campers who opt for using a camping hot water heater.  Some of the benefits include hot water’s ability to kill germs and better cut through dirt, grease, grime and oils while showering or cleaning dishes.  Below we review a number of different types of hot water heaters that can be used while camping and traveling in a camper, RV, or van.  Above is a quick list of our favorite picks for each type of camper hot water heaters.

The Best Hot Water Heater for Your Camper, RV or Van

Camplux Propane Gas Outdoor Portable Tankless Water Heater (2.11 GPM)

The Camplux Portable Propane model is the most versatile of the tankless water heaters for RV, Camper and van users.  This version connects to a propane line or tank and can be used both inside and outside.  It sets up in minutes, so for outdoor use, you can hang it outside your vehicle and attach to a tank and shower or rinse dishes with hot water right next to your vehicle.  If using indoors, make sure the water heater is well ventilated. One way to vent effectively is if a flue pipe is installed additionally (the flue pipe not included).  The ideal operating range for the 2.11 GPM Camplux portable tankless water heater is 3.0~110.0 PSI water pressure. For reference, a typical home water pressure is about 45-55PSI with water faucets reaching up to 80 PSI.  If you’re going to use a water basin rather than a water hook-up, we recommend using a water pump optimized for this unit.  The Camplux 12V Water Pump 65PSI DC 1.6GPM 6LPM, is your best option.
