What is an RV Water Heater? 

RV water heater is a recreational vehicle water heater, which is designed to provide hot water for various purposes while you're traveling or camping in your RV. 

RV water heaters are notably smaller in capacity compared to those found in conventional homes. While a typical home water heater can hold 40 to 50 gallons of water, RV water heaters are much more compact, typically ranging from 6 to 10 gallons in size. Nevertheless, the fundamental principle of heating water remains the same in both RV and home appliances. 

There are two primary methods for heating water with an RV water heater:

  1. Gas: These water heaters require manual ignition of the pilot light, which can be accomplished using a long match or striker. Some models feature automatic ignition, allowing you to ignite the heater with a simple switch inside your RV.
  2. Electric: Electric water heaters in RVs operate when you have access to a 120-volt power source, often referred to as shore power, or when you run a generator. An electric thermostat regulates whether power is supplied to heat the electric element.

Some generators offer electric and gas modes, which can be used separately or in combination to accelerate the water heating process.
