Are you sick of camping and using the navy showers? Would you want to enjoy the great outdoors and a long, warm shower at the same time? You might maybe think about replacing your conventional water heater with an RV tankless water heater.

Let’s start now!

How Do Tankless Water Heaters Work in RVs?

An on-demand solution for heating water is an RV tankless water heater.

Traditional water heaters store water in a tank, adding weight and taking up valuable room to your rig.

Instead of keeping warm water in a tank, an RV tankless water heater warms water via a heat exchanger as you need it.

Now, you can shower without worrying about running out of hot water while also saving weight and space!

What Benefits Can a Tankless Water Heater Offer?

The primary benefit of tankless heaters that people often consider is unlimited and immediate hot water.

You may use hot water for whatever long you choose.

Because the hot water doesn’t run out, you may take 20-minute showers if you wish.

This also means that you won’t have to wait for the water to reheat within the tank before giving your kids a hot shower.

No issue if you forgot to switch on the heating.

There is no need to wait—just switch it on and go into the shower.

Efficiency is another another benefit.

You may conserve gas since you don’t have to keep the heater on constantly to receive hot water right away.

When compared to a tanked option, these heaters are often quite effective in heating water.

They do not lose heat through the tank walls, which contributes to this in part.

Additionally, since they are tankless, they lighten the load on your RV.

When you travel, you don’t need to bring a tank of water with you since tankless units take up considerably less room.

They are also very simple to operate and need little upkeep.

You can take lengthy, hot showers in your RV if it has a tankless hot water heater.

What Are the Drawbacks of a Tankless Water Heater for an RV?

The cost of replacing your current water heater with an RV tankless water heater will be high.

Tankless water heaters use just propane for heating.

Since the majority of RV tanked heaters can heat with either electricity or propane, this might be a drawback if you are connected in and not paying for energy.

Fortunately, compared to a tanked unit, they often have extremely high propane efficiency.

Before the tankless water heater turns on, you must let the water flow for a while.

If you often camp out and attempt to preserve water, this is something to take into account.

Some versions are better suited for boondocking since they can operate at significantly lower flow rates.

The Six Best RV Tankless Water Heaters

These six tankless water heaters for RVs are lightweight and compact.

Although they come in a variety of sizes, the most of them have the same safety features.

Let’s analyze each one so you may choose the one that best suits your requirements.

#1. Truma AquaGo On-Demand Water Heater

About: A few years ago, the German business Truma made its American debut.

Both propane and 12V DC electricity are used to power this on-demand water heater.

Defining Features: The Truma AquaGo On-Demand water heater simply warms the water you need, in contrast to traditional water heaters that retain gallons of water in the tank at all times.

Additionally, it features a little tank that mixes and warms water beforehand so that it heats up rapidly when you need it.

If you want to save money on water or gas, the two modes are excellent.

The “comfort” mode is best for boondocking since it uses less water by preheating its tiny mixing tank.

Finally, because you only heat the water you need rather than a full tank, the Truma AquaGo On-Demand water heater reduces the overall weight of your RV.

Unfortunately, you will need to go to one of their facilities or request one of their mobile technicians to come to you in order to have a Truma specialist install it.
