RV tankless water heater pros and cons

If you are living in an RV, long hot showers may seem like an unimaginable luxury, but they don't have to be. Tankless water heaters are a practical way to provide your water taps with an infinite supply of on-demand warm water.

Tankless water heaters are simple to mount and refit. Without any recovery time, they'll allow you to get uninterrupted hot water. And you're not going to waste propane heating water in a tank that will never be used.

The key reason hikers prefer a tankless heating system over the standard version is that when you're at a full-service camping ground, you get limitless warm water. For big families or full-time travelers, this is perfect.

You do not have to restrict your water usage with a tankless water heater to save hot water.

With a tankless heater, you get hot water on-demand. That ensures that in a tank that might never be used, you will not have to spend money heating up water. You also don't have to wait for hours between each person taking a shower to warm up the water again.

A benefit as well as a drawback, can be the opportunity to pre-set the temperature of the water. Many campers like the ease of always ensuring their water would be set to their level of comfort in the shower or sink. However, if people in your family prefer various degrees of heat, it can be a hassle.

RV tankless water heater Pros:

Like I said, having unlimited hot water is the most actual benefit.

If you have three or more people with a standard 6-gallon water heater in an RV, then you've eventually run out of hot water for either dishes or showers. For RVing, this might not be a quite as big deal as it is when you have a tankless household water heater.

But if you're worried about being careful with money, you'll see some benefits using a tankless model.

If your propane is stingy, then you'll be glad to know that a tankless system uses less gas than a tank system. Since it only utilizes the propane tank when it uses hot water, it can last much longer.

If you use electricity, then this applies as well. With a tankless, you can use less power because it won't fire a water tank when you don't use it.

If a leak is caused by some unlikely occasion, there is minimal damage as there are no gallons of freshwater dripping out of it.

Yeah, there are a lot of DSI or direct ignition heaters out there to give the RV owners calm by not providing an illuminated pilot light for heating water.

However, electrical ignition is used by the newest versions of tankless water heaters, so no pilot light is required at all.

You can set the temperature of your water to whatever you want. If you think your desired temperature is 105°F, you can have a precise temperature in seconds.

RV tankless water heater Cons:

Tankless water heaters each have a minimal trigger for flow. In other terms, the heat exchanger won't turn on if the water flow is too low. That means that you won't have any hot water.

Most of those RV tankless water heaters are not really that big, and you'll get only 2 or 3 gallons per minute. This won't be a concern because water use is usually not very high in an RV, but if you need a few fixtures operating simultaneously, this may be a deal killer.
