Things to consider before buying the best RV Tankless Water Heater

Tank or Tankless

The most important question looming over this entire process is whether you should go tank or tankless. As previously stated, there are advantages and disadvantages to falling on either side of this debate. Tank-based models, for example, will get the job done while costing substantially less than a tankless model upfront. However, these types are larger and take up more room, and they do not provide the technological upgrades that a tankless unit would.

If you go the tankless route, you won’t have to worry with the tank, but you’ll also have a constant supply of hot water. These devices heat your water instantly and only when you need it. Tank-based devices, on the other hand, allow the water inside the tank to lose heat, which means they are constantly working to reheat the water. It is also important to remember that tankless units will wind up costing less in energy bills because they only heat the water when it is needed.

Given this knowledge, it’s simple to understand why RV owners are opting for tankless units. However, the initial cost is much higher, and installation is a little more involved than with a normal tank-based water heater. Overall, both tank and tankless models will do the job, but knowing which one best fits your needs will make your selection much easier. So, please take the time to consider all of the advantages of both and pick which side you prefer.

Water Capacity

Is there a large number of persons aboard your RV? Will you be taking several showers every day? If this is the case, you’ll need a water heater that can produce adequate hot water. With this in mind, it’s critical to evaluate the water capacity of the models you’re evaluating.

Most water heaters have a 6-gallon capacity, however for families traveling together, these typical units will not suffice. If you’re traveling with your family, search for a water heater with a 10-gallon or even a 16-gallon capacity.If you can’t find a large enough unit to meet your family’s hot water needs, you may always reduce your hot water use by taking shorter showers, turning off the faucet after each dish, and using other water-saving practices.

Heating Capacity

The heat output of your water heater is measured in BTUs, which stand for British Thermal Units. The higher the BTU rating, the more efficient the water heater will be in providing hot water.

In other words, looking for the water heater with the largest BTU figure that fits within your budget isn’t the worst way to take in your quest. However, if you do utilize this strategy, make sure that this high BTU model also meets all of your other requirements.

Power Source

Another key factor to consider is the power supply provided by your chosen unit. In this situation, you have three options: battery-powered, electric-powered, and propane-powered.

Determine which of the three can provide you with the most benefits. However, because of its portability, many RV owners prefer battery-powered and propane units. Electric ones, on the other hand, must be fully integrated every time.

Size

Understanding the size you require will make selecting the proper water heater much easier. If you don’t, you might become one of the hundreds of individuals who go online and complain about buying a water heater that doesn’t fit into the spot where their old heater was.

With this in mind, it is critical that you determine the dimensions of your old heater before purchasing a new one. This ensures you never acquire a device that won’t fit into your RV’s setup; so, it’s vital to be careful and know the measurements you’re searching for in your new heater. If you want to acquire the finest tankless water heater for RV, you should know that some models can manage many appliances at once, while others can only handle one faucet at a time. As a result, you must determine how much hot water you will use and if a larger or smaller unit is required.

Ease of Installation

The installation process for these products will have a considerable impact on whether or not you have a positive experience with the product you purchase. I mean, what’s the purpose of getting it if you can’t get it to work in the first place?

Read the customer reviews to avoid purchasing a water heater that you cannot install yourself. These reviews will give you the lowdown on how tough the installation was and whether or not the product is worth purchasing.

You should also be aware that most manufacturers will provide an expert installation add-on, allowing a professional to conduct the installation for you. However, this add-on is extremely pricey, therefore owners on a tight budget should look for a model that they can simply install themselves.
