About this item

Instant Hot Water Supply: Experience the luxury of endless hot water with our RV water heater. With a powerful 68,000 BTU output, it delivers 3.9 GPM of hot water per minute, ensuring you never run out during daily washing, kitchen cleaning, or a long comfortable shower. Unlike traditional tank heaters, there's no waiting time—hot water is available on demand, whenever you need it.
Quick Installation Design for RVs: Measuring 14.96 x 14.96 x 14.18 inches, its compact design fits most RV installation spaces without taking up too much valuable interior space. Opening 12.6 x 12.6 inches also can replace Suburban & Atwood or others 6/10/12-gallon storage water heaters on the market. Installation is straightforward, requiring only a 12V DC power connection and standard NPT fittings, making it an ideal choice for camper water heater and tankless water heater for RV applications.
High-Altitude Performance & Safety Features: Designed for adventure, our RV tankless water heater propane operates efficiently at altitudes up to 9,800 feet (2,987 meters). The high-performance fan and advanced combustion technology ensure reliable hot water supply in any environment.
Built-in intelligent freeze protection automatically activates in low temperatures. Please note: Ensure the RV remains ventilated and powered in low-temperature environments. The water heater's automatic freeze protection activates at 2°C (35.6°F) to prevent cracking and damage caused by freezing.
Energy-saving & Precise Temperature Control: The smart staged combustion control only uses the power needed, so no gas is wasted. That means your propane cylinders last longer, you refill less often, and you save on fuel costs. This RV tankless water heater keeps water between 95–124°F—the perfect range for comfort. It checks the incoming water temperature and adjusts the power automatically, so you get steady hot water no matter the season.
Built-in Safety Features: Equipped with a 203 PSI pressure relief valve, this RV water heater includes multiple safety functions such as flame-out protection, gas leak protection, and freeze protection—keeping you safe in all conditions. It's CSA certified for reliable performance. The built-in forced exhaust fan on top ensures stable combustion, and the system automatically shuts off the gas if the flame goes out. With comprehensive anti-freeze protection, you can use it with confidence even in cold weather.

This was extremely easy installation and so far works good but while taking a shower and that’s the only thing running after about 10 minutes water goes completely cold and you have to turn water off wait about a min and then turn back on with hot water cut down to keep hot water. And my shower head is a low flow so this heater will not put out what they claim

Why did I wait so long to get this. The water literally takes seconds to get hot and I can now take longs showers. I was able to pull the old traditional water heater and replace this myself. Make sure to double check your measurements before ordering. Great investment. The remote to adjust the temperature is amazing.

*UPDATE*
***According to the customer service representative, these units ARE NOT COMPATIBLE for RV service and it is dangerous for use in an RV.
This was the response I received from Ann, customer service representative after she offered to send me a replacement unit. I let her know I would be willing to try the replacement unit but I would not guarantee a change to my review, unless the new unit changed my opinion. She then informed me that her “technicians” said the unit was not compatible with my RV (identical set up to every other RV on the market) and potentially dangerous so she withdrew her offer to replace the defunct unit. ***
I purchased this APUS RV tankless water heater to replace another on-demand unit in my RV, but unfortunately the heater never worked. I spent several hours troubleshooting and verifying the installation. I checked the voltage and all the wiring connections multiple times and confirmed everything was correct.
It was also very difficult to get in touch with customer service. When I finally did hear back from the manufacturer, they suggested the issue was with my wiring. To be certain, I had both an electrician and an RV technician verify the connections, and both confirmed that everything was installed correctly.
After several days of back and forth, the seller eventually refunded the cost of the unit, but the entire process was very frustrating and time-consuming. Unfortunately, based on my experience, I would not recommend this product.

The cabinet is well designed, there's a gasket around the door and the frame has a lip to keep water out also has a way for water to get out in case it ever gets in. Some of the lower end models tankless water heaters lack the water resistance and cabinet drains needed . Overall performance seems well especially for your money. The only downfall I found was the shower head shown in the picture is pretty much useless. There is nowhere for you hook shower head inside the unit. Installation was fairly straightforward.

Everything went together pretty quickly. The package came damaged, and the outside door was pretty tweaked, luckily for these guys I opted to bend it back straight, you can barely notice now 🤷‍♂️
One other small gripe is that the output port will not accept a typical swivel connection will not create a seal on account of the internal diameter of the output is not large enough for the nipple to fit, instead it only jams and the rubber bushing won’t contact.
I ended up using a standard fitting for that side, after yet another run to the depot.
So far I’ve only taken 2 showers and used the sink half a dozen times.
It does seam to work very well. The water gets hot very quickly and I typically only need to let the water run about 10 seconds til it gets hot.
I will update this if things change but for now, I think I’m pretty happy with this set up.
I give it a two out of 10 in terms of difficulty installing, but I am a 20 year technician in virtually all of the trades so maybe for the average person it would be five or six out of 10?
