When we turn on the faucet to wash our hands, do the dishes, or take a lovely, warm shower, we take hot water for granted.

But while we’re camping, we rapidly develop a fondness for—or a profound need for—immediately accessible hot water.

This is where the RV tankless water heater comes into play.

Let’s look at this miraculous device that gives everyone, whether they are connected to the grid or not, the power of ready-to-use hot water.

How Do Tankless Water Heaters Work in RVs?

A standalone appliance known as an RV tankless water heater provides hot water quickly and only when you need it.

If you’re linked up to municipal water, you may have an endless supply of immediate, on-demand hot water from a single source, but if you’re boondocking, your options are obviously limited by the capacity of your water tank.

This compact, more effective heater heats water as it passes through it.

A tankless device only warms the water when you turn on the faucet, as opposed to a tank storage water heater, which continuously heats the water stored in the tank.

Since it doesn’t hold any water, utilizing hot water in your RV will save you both room and gasoline.

What Are the Prices of RV Tankless Water Heaters?

Some versions call for the purchase of extra components, such as access doors.

Depending on the size and capacity of the water heater you’re upgrading, you’ll need a certain kind of door.

The good news is that because installation is quite simple, there shouldn’t be any extra labor expenditures.

The majority of heaters are compatible with current electric switches and operate on propane.

Advantages Of A Tankless Water Heater For RVs

The lack of waiting for the water to heat up is one of the main advantages.

(In reality, there is a little delay, but it doesn’t last long.) Additionally, tankless water heaters use less energy.

Instead of heating six to ten gallons at a time, you just heat the water you really need.

Less propane or electricity is used in this.

Additionally, you won’t have to pay to heat water that you don’t use.

Additionally, you don’t have to wait for the water to be warmed after another person’s shower.

With an RV tankless water heater, there is no need for what is known as “recovery time.”

Additionally, a tankless water heater’s water won’t abruptly become cold and scald you.

As long as there is a water source, it remains heated.

You may keep showering till you’re wrinkled and red if you’re in a full-service campground where you’re connected to water.

Tankless water heaters are also more space-efficient.

Some are just about half as big as the conventional water heaters they may quickly replace.

Because there isn’t a water tank, they are also much lighter.

In other words, using less fuel or diesel while towing may save money.

An Rv Tankless Water Heater’s Drawbacks

Despite the fact that the majority of customers like their RV tankless water heater, there are a few drawbacks you should be aware of.

They may be pricey, to start.

The cost may not be worthwhile for you if you don’t really appreciate having hot water available whenever you need it.

Second, propane fuels the on-demand heaters.

Even though they are energy-efficient, you should anticipate using gallons of propane each month.

Last but not least, despite RV tankless water heaters’ claims of being “instant” or “on-demand,” there is still a little delay before the hot water starts to flow.

When you open the faucet, you may anticipate a 10–20 second delay in the supply of hot water.

Most customers claim that this is merely something new users need to get used to and not a real drawback.

When Purchasing A Tankless Water Heater, What To Look For

Think about the kind of RVer who might benefit from a tankless water heater first.

An RV tankless water heater will be most useful to full-timers or families that travel often.

The likelihood of using a lot of hot water on demand is higher.

Before investing in a tankless water heater, you should think about the size of your present water heater.

Most must suit the space and are designed to replace the current water heater.

In addition, as we previously said, you will need to purchase the access door individually.

Therefore, before buying the door, carefully measure the length and breadth of your exterior compartment.

Finally, check the displays to be sure they are ones you can readily see and use.

Some are “user-friendly” and others are not!

The following was added by a person going by the username Jayhawkclint: “We have used tank and tankless heaters from Atwood and Suburban.

Our previous tankless had a 50k BTU and could provide hot water, but it was flow sensitive.

All other water heaters pale in comparison to this Furrion model.

It resembles a hot water shower at home in every way.
