If you’ve been camping long enough, you’d know that we’ve come a long way from the uncomfortable and primitive days of roughing it. Thanks to high-tech gear and accessories, campers can sleep in the great outdoors while enjoying some luxuries from home.

This also means you don’t have to forego a nice, warm shower just because you’re outdoors. That is if you have an electric water heater for camping.

In this article, we’ve rounded up great electric-powered water heaters for camping showers. We also answered your most pressing questions about this amazing technology in the FAQ section, so stick around.

How does an electric water heater for camping work?

Water heaters for camping in the market can generally be categorized into two: propane-fueled water heaters and those that are powered by electricity.

They work in the same way: cold water passes through the shower unit, almost instantly heating it by the time it reaches the showerhead or faucet. The difference lies in the power source.

While tankless propane water heaters rely on, well, propane and either D cell batteries or electricity to ignite, an electric water heater for camping typically needs a 120-volt shore power (or 240 volts in rare cases), or a camping generator.

Electric water heaters use a fairly substantial amount of electricity (about 12 amps or 1,400 watts). That’s why most campers still prefer the more economical propane water heaters. However, if you’re traveling on an RV or camper van, electric water heaters make a lot of sense.

How do you choose the best electric water heater for camping?

Aside from pricing, the first thing to consider when choosing an electric water heater for RV is the size of the unit relevant to the space you have in your RV.

Depending on how much space you can spare, you should also decide whether to get a tank model or a tankless one. Mini tanks won’t take a lot of space but their small capacity will also mean your usage will be limited. If you plan to take showers with it, don’t go lower than a 6-gallon tank volume.

If you wish to linger in the shower, choose tankless electric water heaters like EcoSmart ECO 11. It requires less space and needs water as needed.

Other considerations include energy efficiency, flow rate (but this is also dependent on your showerhead), temperature range, quality of the materials, and built-in safety features. Having overheat and anti-freeze protection is always a plus.

Which is better for camping: propane or electric water heaters?

It depends.

If you’re after portability, propane water heaters are more ideal since they don’t have to be plugged in. But if you’ll be staying in a place where there is shore power, electric water heaters will make sense.

As for fuel costs and energy, propane water heaters are also more efficient. A propane tank can last you a long time, while electric water heaters consume a substantial amount of power. To offset this, you can use an alternator charger to heat the water while the RV or camper van is running.

How else can I heat my shower while camping?

Besides traditional water heater units powered by either propane or electricity, you can also consider immersion heaters like GESAIL. These portable items are great if you already have the necessary accessories for shower systems: the showerhead, pump, bucket for your water, and your tent shower.

Can I leave my water heater on?

Unlike propane water heaters, it’s safe to leave your electric water heaters running. But it’s much better to turn it off between uses to save energy. If you’re running it on battery, you don’t want it to drain your power.

In addition, you have to make sure to not leave the heater on while the tank runs empty (if you’re using a tank system). When the unit heats in the absence of water, you risk burning the unit and your RV.

Are electric water heaters for camping safe?

Electric water heaters are generally safe. They produce no carbon monoxide and pose no threat of combustion or explosion. But, if not installed or maintained properly, they can also be dangerous.

If an electric water heater’s thermostat fails, the water can become too hot and severely burn you. It can also cause a fire hazard. Additionally, since it involves electricity, damaged units can also pose a risk of electrocution.

To avoid dangers like these, check the instructions from the manufacturer and ensure proper maintenance of the unit.
