Tankless RV water heater: all you need to know

Nobody likes taking a cold shower. But in RVs with standard water heaters and smaller holding tanks, it always happens. It’s much more galling if you have several people attempting to take a shower in your camper. Then so, the need for instant hot water becomes more demanding.

Like that in your home or RV, the standard water heater is unreliable since its holding tank is limited. It also uses a lot of energy because the tank has to be heated all the time. And one more thing, storing hot water that may or may not be utilized is uneconomical.

Modern RVs, on the other hand, are outfitted with tankless water heaters. A tankless RV heater is a new trend in RV heaters that fights the cold water. While on a trip, it becomes the solution to an infinite stream of hot water.

Benefits of a tankless water heater

Today, a tankless unit designed primarily for RVs has gained popularity in the outdoor world. Since its conception, RV manufacturers have taken the opportunity to install tankless RV water heaters to their modern campers, given the remarkable benefits that they have to offer. Besides, new RV customers are increasingly expecting their high-end RV units with tankless heaters. Moreover, the tankless device is an upgrade to replace the old-style RV water heaters; more practical RV owners are switching to it. Here are the pros of using tankless RV water heaters:

  • The continuous supply of on-demand hot water: The primary function of a tankless RV water heater is to generate limitless hot water whenever there is an urgent demand. It operates in complete contrast to the standard version, which stores water in a tank and consumes more energy to keep it warm until someone uses it.
  • The word “tankless” implies that you are not limited to a hot water source through a tank. It does not need a tank container. The tankless version provides hot water as long as the water supply is running. In contrast, the tanked version can only store water and is determined by the capacity of a tank. You may have a hot shower and other usages for as long as you want with the tankless RV heaters.
  • You may utilize hot water with no resting time. When you turn the hot water knob on your faucet, it immediately generates warm water. It means you don’t have to wait a specific amount of time for the water in the tank to heat up. Or wait for hours between each person in the shower for the water to heat up over.
  • Another advantage of using a tankless unit in an RV is that they are small in size. It is lighter and may take up less space inside the RV, especially if you have a small RV or travel trailer. A standard propane or gas RV water heater has a 6-10 gallon tank that can take up a lot of space. The instant RV water heater, on the other hand, is just half the size of the standard ones.
  • A tankless RV water heater conserves both propane and electricity. The tankless unit is powered by either propane or electricity, or both. And because it only warms the water when needed, it uses less gas or energy, saving you a lot of money.
  • A tankless RV water heater makes your journey more convenient. The temperature control panel allows you to pre-set the temperature to your preferred degree of comfort. It is essential if the members on-board have different choices for the temperature of the water.

Different models of RV water heaters

When traveling during the winter, having an RV water heater is essential. And it all starts with knowing what type of heater you require. Various kinds of RV heaters are available, including gas, electric, and combination heaters that all operate on the same fundamental concept but differ in startup and water heating capabilities.

Keep in mind that the model you choose should depend on your own needs. If you are staying at a full-service campground, an electric RV water heater is the best option. However, in such a case, the hybrid gas/electric type may be a good alternative. But, in areas where power is not available, propane gas is the most cost-effective option. And, for family campers and full-time campers, a tankless RV water heater is the best unit for delivering an abundant on-demand hot water source for the entire family.

1) Electric model

All-electric models, in essence, require power to function. If there is no shoreside electrical power accessible in the area, you can use a generator as a power source. An electric water heater employs heating elements to produce hot water. When utilized, the unit uses energy, and considerably more power is consumed when using the appliances simultaneously. It includes a direct-spark ignition system that allows you to turn it on instantly using a switch. It is the ideal model when staying at a full-service campground.

2) Propane Gas model

A propane type also features a pilot ignition that requires manual lighting of the pilot light starter. It’s an entry-level model that can run in any circumstance as long as propane gas and 12V power are available. After igniting a spark, it creates a tiny flame in the heating tube, which subsequently heats the water in the tank. The tank usually has a capacity of 6-10 gallons. The 12v power then allows you to switch to cut off the flame after the heating is complete. A propane gas water heater performs well in providing hot water, especially when boondocking and in campsites where electricity is inaccessible.

3) Hybrid gas-electric model

A gas-electric RV water heater may provide you with the best of both components, which are frequently utilized in sync to provide you with the most remarkable outcomes. The combination of electric and gas power quickly warms the water. This hybrid option is ideal if you frequently stay at campgrounds that provide electricity.

4) Heat exchanger model (MotorAid heater)

The MotorAid water heater simply transfers heat energy from the RV’s engine cooling system to the water heater. This means that the average heating temperature of the engine serves as the heating component for the heating tank. It continues to heat water as long as the engine is running. As soon as you get to your location, you will most likely need gas or electricity to keep the water heated at all times.

5) Tankless model

The items mentioned above are good, but tankless RV water heaters outperform them all as to some users. A tankless RV camper water heater is a novice innovation that solves insufficient hot water on every RV journey. When turning on the switch, the water going down the pipes warms up quickly, resulting in an infinite supply of hot water on-demand as long as the water source is kept on. It may be a bit more expensive than the tanked version, but it gives optimal convenience that makes you feel at home.

Things to look for in a tankless RV camper water heater

Sift through its specs to fully understand how RV heaters perform. And by doing so, you will be able to define everything quickly and, hopefully, find the ideal tankless heater for your RV.

Here are some things to consider when purchasing a tankless water heater for your RV camper.

Brand

Whatever brand of tankless heater you get for your RV, as long as you feel it will serve you well, go for it. Remember to go with the brand you have confidence in.

Size

Remember to measure the size of your previous RV heater. All RV heater models can accommodate a particular camper model.

Safety standards

  • Look for devices that have been certified to meet CSA safety requirements. The Canadian Standards Association certifies mechanical and electrical items that provide a high risk to end-users.
  • To guarantee your family’s safety, look for flame failure protection, anti-freezing protection, anti-oxygen depletion, and overheating protection.

Flow rate per GPM

GPM or gallons per minute determines the average flow rate of a heater. 6-7 GPM is recommended in RVs with a standard single bathroom.

Heating capacity
The British Thermal Unit (BTU) is a tankless heater’s heat capacity. In general, an RV used just slightly less heat than a home with big bathrooms. Typically, just 30000 to 50000 BTU are available. The higher the rate, the faster it will be able to heat water.

Water pressure

The pressure of water pulls the water through the pipes. And a water pressure operates, depending on the conditions of your RV’s plumbing system. Modern RVs can handle up to 100 PSI (pounds per square inch). Somehow it is recommended not to go over 60 PSI to protect the system.

RV tankless water heater easy install/replace

One of the crucial things to do is replace the standard water heater with a tankless water heater before leaving for your next RV trip. A tankless RV water heater is just easy to install.

Easy step-by-step instructions and procedures:

  1. Make sure to turn off the connections and remove the water supply before switching the unit.
  2. Disconnect the gas, water, and electricity after turning it off and remove the old unit.
  3. To remove the heater housing, unscrew the door and pull it out.
  4. To get an even surface, gently cut around the seals using a cutter.
  5. After that, you may remove the existing unit from the hole.
  6. Scrape away all of the old sealants; you may clean the residue with a solution.
  7. Measure the hole to determine the correct size for the new tankless unit.
  8. Slide the replacement unit into position.
  9. If there are any gaps left after installing the new unit, fill them with flushings or sealants.
  10. Place the door in place and line up the holes on the door that correspond to the holes in the water heater and screw them in place.
  11. After that, you need to thread the screws around on the outside of the vehicle to fasten it.
  12. Apply a bead of silicone all the way around to seal it against moisture and water from the outside.
  13. Then begin connecting the 12v electrical components ( black for ground and red for positive).
  14. Then, connect the water pipe (hot/cold) to the unit.
  15. Install the control panel in an accessible location, switch it on, and set the temperature to your preferred level of comfort.
  16. And now everything is in place, and your new tankless unit is on and working.

More words

Most RV campers with tankless water heaters choose to have a lower water temperature on the water heater settings so that taking a shower does not add a lot of cold water to the system. If there is insufficient flow through the water heater, it will not turn on, and you will not have any hot water. As a result, rather than turning it up too high, it is best to set it closer to the desired water temperature.

Tankless water heaters are becoming increasingly popular among RV campers and travel trailer owners. The vast majority of them claim to have reaped the numerous benefits of utilizing such a device. Simply because a tankless water heater provides unlimited hot water and is simple to use, it includes an intelligent control panel that lets you change the temperature to your liking. Parents might appreciate the opportunity to pre-set the hot water temperature to a lower, child-safe degree. In addition, the control panel has a visible diagnostic monitor for easier troubleshooting.

RVers and outdoor enthusiasts traveled a lot and loved spending the entire day outside for active sports. After a long day of biking, trekking, fishing, and other outdoor activities or cold-weather hobbies, they would surely appreciate a hot shower. A typical water heater will work, but with a 6-liter tank capacity, hot water depletes fast. And before you know it, you’ve run out of hot water.

A winter road journey is also exciting and enjoyable. But after a few hours of being outside in the cold, your body becomes chilled, and your muscles tense. That is why hot baths help to alleviate muscular tightness and frostbite. When hot water reaches your skin, it increases blood circulation, which subsequently relaxes and rests your muscles.

Going tankless is all you need to experience the comfort of a lengthy hot shower on your RV journey.

Finally, say goodbye to cold water in your RV. There is no need to worry about running out of hot water. And no more chilly running water from the sink when doing the dishes. The best tankless RV water heater is all you need for an infinite supply of hot water that everyone will enjoy. When you travel, your RV becomes your home, and it feels lovely to be able to enjoy all of the comforts of home while on the road, including a long hot shower. Hit the road and enjoy the great outdoors!
