Make sure the new heating unit does not snag or catch on anything when it is being slid into the recess in order to install it properly. Completely seat the device and ensure that it is sitting level before moving on to the next step Once you’ve verified that everything is in working order, you can proceed by gently drawing the unit out; this will assist to ensure that it is properly balanced while also allowing enough area to seal the flange.

Take the time to double-check that the mounting holes on the new tankless unit correspond to the holes on the old tankless unit; if required, you may drill additional holes.

You’re now ready to complete the internal connections and connect the new heater to the service lines that were previously installed.

4) Reconnecting to Service Lines

If you’ve done everything right up to this point with your new tankless water heater, connecting it should be a piece of cake. First and foremost, make certain that the relevant water lines are connected to the appropriate locations on the heater. Keep an eye out for any of the fittings that could be cross-threaded afterwards. Last but not least, avoid over-torquing any of the fittings – you don’t want to accidently break the fittings off the heater when tinkering with them. As an alternative, you may use a second wrench to keep the tank fitting in place while you tighten the hose fitting.

On the outer flange, you may now tighten and secure all of the screws in place using a screwdriver.

Install any necessary vent fittings and close the heater’s door after the unit has been properly assembled and secured.

It is now possible to connect the hot and cold water connections to the unit. You’re all set now! To finish, just turn on the hot water, check the flow of water, and adjust the temperature to your preference. Wikiocean.org is the source of this information.

Measure the size of the aperture on the outside of your RV, to be more specific. If the tankless you’ve been eyeing is too large to fit through your sidewall, it’s normally easy to widen the aperture, but you may want to hire an expert to handle the job.

Should You Hire a Specialist?

Whether you want to install the tankless water heater yourself or hire a professional to do it for you is largely dependent on your level of experience with tankless water heaters and recreational vehicle maintenance. For the most part, some types are rather simple to install, and you can generally just connect the water heater to the electrical and water lines without too much difficulty.

What to Look For In a Tankless Water Heater

If you’re thinking about upgrading to a tankless water heater or buying one for your RV, you’re probably already aware of the various advantages that tankless water heaters have over the standard storage-tank kind. The fact that there is no heat loss from standing water makes tankless water heaters, also known as demand-type water heaters, more energy efficient than traditional water heaters. Therefore, because there is no need for a large, heavy water tank, tankless water heaters are significantly smaller and pose less risk of leakage, possibly saving thousands of dollars in property damage.

On a chilly morning, there’s nothing more frustrating than wanting a good hot shower only to discover that your water is barely tepid and becoming colder.

Nonetheless, before rushing out to get your own ticket to water heating in the twenty-first century, there are some factors that must be considered before bringing your own tankless water heater home and what criteria should be used when picking the proper model:

Water Usage

Before you begin looking for a tankless water heater, you should have a rough idea of how much water you use on a daily basis. Listed below is a short reference for the most common water-consumption appliances:

  • Twelve-gallons-per-minute toilet
  • Two- to-four-gallon-per-minute bathtub
  • And one-and-a-half- to three-gallon-per-minute shower 1 – 12 gallons per minute in the kitchen sink
  • 1 – 3 gallons per minute for the dishwashing machine

When selecting a traditional water heater, you may need to consider how frequently you expect to use these items in a given day; however, when selecting a tankless water heater, the more significant question is how frequently you expect to use numerous appliances at the same time. Tankless water heaters are capable of heating water on demand at rates ranging from two gallons per minute to an amazing six gallons per minute, depending on the particular type.

Location

While one of the advantages of a tankless water heater is that it requires less storage space, you should still make sure that the location you choose is one that can be readily linked to the rest of the house. You have the option of mounting your tankless water heater on the outside of your home or RV. Whatever your situation, whether you live in a region where temperatures routinely fall below 0 degrees Fahrenheit, or whether you are attaching your tankless water heater to a recreational vehicle that is occasionally parked in freezing temperatures, all you need is an anti-freeze kit that you can attach to your unit.

CostRebates

As with any purchase or upgrade decision, it’s critical to examine your individual requirements as well as your current financial condition before making a final decision. A tankless water heater may be slightly more expensive than fixing your present water heater; nevertheless, you must consider the long-term savings in energy expenditures when comparing the two options. Keep in mind that when you are ready to make a purchase, you should double-check to see if there are any tax credits or rebates available in your state.

Electric or Gas

According on your location and the electric grid you are connected to, a gas or electric hookup may be less expensive or more expensive depending on your needs. Tankless water heaters fueled by natural gas are on average less costly per unit than electric tankless water heaters and have somewhat greater flow rates. The fact that some tankless water heaters come with electric connections does not deter many people from choosing propane-powered models since they are easier to install and because needing to refill the propane on a regular basis is well worth the enhanced flow rate offered by gas units.

Design

While we all wish we were a little bit more handy, for those who are not technically inclined, a tankless water heater is a much simpler device to operate than a large tank of water with a pilot light in the tank. When shopping for a tankless water heater, be sure to get one with a display that you are certain you will be able to operate properly.

If you require hot water for a shower in your RV, you may be able to avoid purchasing a whole home system if you use a portable water heater. It has been proven by several studies that a simple portable tankless water heatercan make all the difference at a fraction of the cost

Do Tankless RV Water Heaters Provide Endless Hot Water?

Is it true that tankless RV water heaters deliver virtually limitless hot water? The small print, exclusions, and nuances of a $500-$1,000 purchase like a tankless RV water heater will always be important to the sensible seasoned RVer when considering such an investment.

However, while RV tankless water heaters are a significant improvement over traditional tank models, they are not suitable for every camping style.

Do Tankless Water Heaters Always Have Hot Water?

Tankless water heaters provide constant access to hot water and live up to their reputations in the process. They function by directing incoming cold water through a lengthy conduit with several bends to the desired location. As the water travels through the line, the heat source in the component heats the tube, boosting the temperature of the water in the process. When the water enters the sink, shower, or washing machine, it is at the appropriate temperature for the task at hand. Tankless water heaters, like RV tank water heaters, must be programmed to a precise temperature before use.

When the RV tankless water heater is in operation, you will not be able to adjust the temperature of the unit.

Recreational vehicle owners, particularly boondockers, like the convenience of having fast hot water and enjoying a long, soothing shower.

People, on the other hand, frequently overlook the storage capacity of their grey water tank.

Three Reasons a Tankless Water Heater is Worth It in an RV

When it comes to hot water, tankless water heaters deliver on their promises every time.

1. Tankless Water Heaters Provide the Best Return on Investment

Seasonal and full-time positions are available. When it comes to RV water heaters, tankless water heaters provide the highest return on investment. As a result, you will save a large amount of money on your power bill because the majority of month-to-month camping sites have metered electricity. Tanked water heaters consistently maintain the temperature of the water, ensuring that it is ready for use anytime it is needed. When the hot water faucet is turned on, an electric intermittent ignition device (IID) heats the water line, eliminating the need for a traditional tank.

A tankless water heater can help you lower the Gross Vehicle Weight (GVW) of your RV by 50-83 pounds by replacing your existing tank. Eight and a half gallons of water weigh 8.34 pounds each. As a result, a six-gallon RV water heater tank can contain 50.04 pounds of water, whereas a ten-gallon tank can hold 83.4 pounds.

What would you do if you had a little additional weight?

Learn how RVers, both new and experienced, deal with the weight issue and other challenges that arise in the RVing world.

3.RV Tankless Water Heater Water Flow

The typical tankless water heater has a flow rate of six GPM, which is considered to be standard. Models range in size from 4 to 10 GPM. If you set the hot water faucet down to a trickle, it is possible that the gadget may not come on. You’ll need to open the faucet just enough to for the water heater to turn on. Each water appliance has a specific average flow rate in gallons per minute.

  • Sinks in the bathroom and kitchen: 1-2 GPM
  • Dishwasher: 2-4 GPM
  • Shower: 1.5-3 GPM
  • Washing machine: 3-5 GPM

What if you’re in the shower and someone else accidentally runs the water and turns it into a boiling inferno? This is a scenario that many people have experienced. When you put too much strain on your RV’s tankless water heater, your spa-like shower transforms into an arctic blizzard. When you do a fast study and make a few modifications, such as running the dishwasher at night instead of in the morning, you may significantly reduce your hot water use during peak usage periods. As a result, you can save money by choosing a tankless water heater with a lower flow rate (e.g., 5 GPM) rather than a higher flow rate (10-16 GPM).

If the campsite has low or high pressure, this might interfere with the tankless water heater’s ability to function properly.

Is it Easy to Replace an RV Water Heater With Tankless?

Despite the fact that the device is self-contained, it is not simple to replace an RV water heater with one that has the tankless capability. Every model comes with a detailed instruction booklet that walks you through the process of connecting the electricity and propane lines, but there’s more to it than that. Water heaters for recreational vehicles that do not use tanks are often smaller in size. You’ll need to install wood or aluminum support braces to ensure that they’re properly secured.

One of the most difficult facts of the recreational vehicle industry is that there are no standardized parts.

If you’ve found the perfect external door, you’ll want to make sure it’s the proper color: white, beige, brown, or black, for example.

Typically, a tankless water heater will last up to 20 years, but a tanked water heater would need to be replaced after 15 years.

Do Electric or Propane Tankless Water Heaters Work Better?

It all comes down to whether an electric or propane tankless water heater is more appropriate for your RV lifestyle requirements and desires. Each version offers a number of benefits that make it deserving of being included on your shortlist.

Electric RV Tankless Water Heaters

Electric RV tankless water heaters are ideal for boondockers since they consume as little as four watts and are solar system friendly. A few seconds more (between 3-5 seconds) is required for electric versions to reach temperature, although this is nowhere near the time required for its tanked counterparts. It is less complicated to install a tankless electric type since there is no need to connect a gas connection. Due to the fact that you will be utilizing electricity rather than propane, high altitudes will not be a problem if you are camping in the mountains.

Propane RV Tankless Water Heaters

Tankless water heaters fueled by natural gas, on the other hand, heat water more quickly and are available in the highest GPM capacities. Also if they include a condensing component, the exhaust is used as an additional source of heat to warm the water before it is vented back into the atmosphere. RV tankless and tanked water heaters are also equipped with an electric intermittent ignition device (IID) rather than a continuous burning pilot light in order to conserve fuel. Consequently, you will not experience the gradual fuel drain that RVers experienced throughout the Classic Era (1971-1989).

If your carbon monoxide alarm goes off, it’s possible that something is wrong with your propane burner and you should investigate more.

If the CO alarm sounds, immediately turn off all propane-burning equipment and contact an RV service facility or mobile repair expert as soon as possible to get it repaired.

Only you can assess the importance of a difference of ten percentage points in the broad scheme of things. Check out the side-by-side table below for a well-organized chart that compares the characteristics of electric and propane RV tankless water heaters in terms of performance.
