What Is a Tankless Water Heater?

What To Look for in an RV On Demand Water Heater?
Cutting your dependence on a water tank can help you lower your cost and travel easier. Before making the switch, think about your actual water usage.
Larger families and regular RVers will get the most benefit from a tankless water heater. Most tankless units are made to able to fit in the space of the traditional heater.
Ease of use is also an important factor to look out for. Some tankless units are complicated and hard to operate. If you have a lot of small or elderly travelers, it is important to choose an RV tankless water heater that is user-friendly. You will also want to find a tankless unit that matches your power preferences.
Do you like to remain hooked up most of the time? If so, an electric model is ideal. For those that are most often on the road, a gas-powered unit is a better choice. Of course, you can also pick up a hybrid to get the best of both worlds.
Is Switching to a Tankless Water Heater in an RV Worth It?
Switching to tankless water heaters for your RV is worth it if you are in need of more space or increased fuel storage. It is also a great investment for those who spend a lot of time in their RVs or who live in them full time. Localized heating systems for your water will help reduce the amount you pay for your electricity.
However, for occasional RV users, the initial investment in a tankless heater may not cover the cost in savings alone.
The advantages of installing a tankless water heater in your RV are numerous. They have increased in popularity because they deliver a regular supply of hot water and use less energy as we mentioned.
One of the financial benefits of using a tankless water heater is that they have a longer lifespan than traditional heaters. When you don’t have to take your RV to a specialist for repair or servicing, your overall cost is further reduced.
The cost of ownership of a tankless water heater is also much lower in general than a traditional tank. Because they use less energy, the cost of operation is much less than traditional options.
Even though the upfront cost can range from $300 to $1,000 for a tankless unit, there is very little maintenance required.
Traditional hot water heaters are much heavier and take up a lot of space. Tankless heaters for your RV are extremely compact which frees up space for other features.
Using a tankless heater is much safer for you and your traveling companions as well.
There is no chance of overheating because the unit will turn off when not in use. You also won’t have to wait for the tank to fill up and the water to get hot because it will be heated at the faucet on demand.
The weight of a tank will be eliminated from your RV which will give you better gas mileage over the long haul.
As we mentioned earlier, there is less maintenance such as cleaning a water tank, flushing the system, or dealing with hard water.
What Are the Cons of a Tankless Water Heater?
Tankless water heaters have a lot of benefits, but there are some drawbacks you should be aware of.
They have a higher upfront cost which can make it hard to obtain for some RV owners. Installation can be complex for some of the higher-end models or even some basic models. If you are not near a specialized service center or purchase a tankless heating unit off the shelf, you may not be able to set it up on your own.
Tankless water heaters also have a lower output than traditional heaters. They are made to facilitate a lower flow rate in order to heat the water at the point of use. Though the flow rate can be increased slightly on most models, it will result in a lower water temperature.
Most tankless units will also work only for a single faucet which means you will need multiple units for multiple areas. There are multi-tap tankless heaters as well, but, they are very costly in terms of upfront investment.
What Size Tankless Water Heater For RV?
Just like with traditional water heaters, tankless heaters for RVs come in different sizes. The openings will differ depending on your desired flow rate and some units will be larger in order to accommodate multiple taps. Tankless water heaters are rated according to their flow rate compared to their maximum temperature at that rate.
In order to understand what size unit is best for your RV, you need to think about how many taps you will use at once.
For example, if you want to use the shower and a sink faucet at the same time, you will need to have a flow rate of 3.2 gallons a minute.
Next, you will need to look at the temperature rise of the unit to prevent undersizing. Warm climate RVs will need a lower temperature rise than RVs who are typically in colder areas. The average user will need a 55-degree temperature rise.
So, in order to get the right size, calculate how many areas you will need to use at once and your flow rate to get the proper sizing.
Do Tankless Hot Water Heaters Run on Propane or Electric?
Tankless hot water heaters can run on propane, electricity, or a combination of both in a motorhome. They are also relatively quiet as far as add-ons go.
The choice of energy source will depend mainly on how your RV camper is set up.
RV gas tankless heaters are able to heat the water quickly and are ideal for those who tend to boondock more frequently.
RV electric tankless water heaters take a slightly longer time to heat the water. They are great for RVs that spend most of their travels hooked up to shore power. Electric models are cheaper to use over the long haul, but in general, the difference in cost is negligible.
