I Tested And Reviewed 10 Best Outdoor Propane Tankless Water Heater (2023)

After owning this heater for 2 years, I can confidently say that it is truly amazing. With the exception of one breakdown due to a faulty part, which was promptly replaced under warranty by the manufacturer, this heater has performed exceptionally well. It consistently maintains hot water temperature for as long as you need it and does not experience any drop in hot water pressure, even when running multiple appliances such as a bath, shower, and dishwasher simultaneously. I highly recommend this heater without any hesitation.

In terms of its positive features, this heater heats up quickly, providing hot water within a minute even on floors located two levels above. It also offers an endless flow of hot water, allowing for multiple showers to be used simultaneously without any issues. I have not fully tested the limit of how many faucets can be used at the same time, but it has handled multiple appliances without any problem. Additionally, this heater operates quietly and fulfills its intended purpose perfectly.

However, I did encounter a negative experience during the ordering process. I selected this water heater from Amazon, which offered an Amazon Installation Service option that I chose. The heater arrived promptly and in good condition. However, when the Amazon-approved contractor arrived to install it, they refused to proceed as they had not realized it was a tankless heater and had concerns about warranty issues. This left me in a difficult situation as our existing electric tank heater had recently broken down, leaving us without hot water and three young children to take care of.

In an attempt to find a solution, I asked the contractor to inspect the electric heater and see if there was a simple fix. They offered to book the job for $150, but believed it would require internal repairs. Fortunately, when we eventually found a local installer for the new heater, they took the time to examine the existing heater and discovered a simple fix involving a reset button behind a small panel. The heater started working again without any further issues.

We then contacted Amazon to request recommendations for alternative installers. The representative from Amazon installation services went above and beyond by reaching out to local plumbers, but unfortunately, none of them were willing to install a tankless heater that they had not sold. Amazon did provide a refund for the installation fee and offered a $30 credit to compensate for the inconvenience.

Ultimately, we were able to find a local plumber who was willing to install the heater. I also reached out to the manufacturer of the water heater to confirm that the warranty would still apply if a registered professional plumber installed it, and they confirmed this to be the case.

I recently purchased an on-demand propane water heater for my jacuzzi tub in my greenhouse, and I have been extremely satisfied with its performance. After conducting extensive research, I chose this unit because I wanted to be able to fill my tub as needed, have hot water at the desired temperature, and avoid the need for a large hot water tank.

Installation was a breeze and took me only about half an hour. Following the instructions provided, I initially ran the unit with the showerhead in the tub to start filling it. Within seconds, there was significant steam coming up from the tub, indicating that the water was heating up quickly. I did have to adjust the temperature slightly, but once I found the right setting, it consistently provided hot water.

One of the standout features of this on-demand water heater is its ability to produce all the hot water I need. Despite my well water pressure not being the greatest, the unit continued to deliver hot water without any issues. It has a safety shut-off feature after 20 minutes, but I found that simply turning the water off and on again immediately restarted the heater, bringing the water back to the desired temperature within seconds.

I have been using this water heater for four years now, and I am happy to report that it has performed flawlessly. I even decided to hard-plumb it into the hot water feed of my jacuzzi tub, and it has had zero issues since then. The two rechargeable batteries it requires typically last a year before needing to be replaced, and the unit continues to fire up instantly and provide piping hot water.

While the water heater is installed under a roof, it is exposed to the humid Florida weather year-round. Over time, a few bubbles in the paint developed, but I was able to address this issue by peeling off the chipped paint and applying some Rustoleum in an almond color. This stopped any further rusting, and since aesthetics are not a major concern for me, it was a practical solution.

I estimate that I use this water heater to fill my 240-gallon tub around 200 times a year, and it has consistently met my expectations. I am thoroughly satisfied with its performance and durability. This water heater has truly proven itself to be reliable, earning it a well-deserved 5-star rating.

Gasland Outdoor Shower Heater – A Reliable and Customer-Oriented Choice

I recently purchased the Gasland Outdoor Shower Heater for use in my outdoor shower during the summer and early fall. Having used another brand in the past, I decided to give Gasland a try, and I must say, I am thoroughly impressed.

One of the standout features of this heater is its ease of use. Setting the dial to the desired temperature is a breeze, and it maintains an even hot water temperature throughout the shower. This allows for a comfortable and enjoyable shower experience tailored to individual preferences.

In terms of customer support, Gasland has exceeded my expectations. I had a few questions regarding the product and reached out to the company. They promptly responded to my email, providing comprehensive answers and addressing all my concerns. Their attentiveness and willingness to assist further reinforced my confidence in their product.

Safety was a paramount concern for me, as I intended to use the heater near the wood of my shower. To mitigate any potential risks, I took precautions by covering the cedar behind and along the entire length of the product. Additionally, I opted to connect the heater to a water hose and mount it securely, ensuring its stability throughout the season. Gasland's product design, as depicted in the provided pictures, showcases a metal shield and proper venting, further enhancing safety measures.

During the pool and mowing season, I employ a cover to protect the heater from rain and water. This ensures its longevity and performance. When storing the heater, I take extra care to prevent any entry of bugs or spiders, guaranteeing its pristine condition for the next year's use.

The quality of the Gasland Outdoor Shower Heater surpasses that of my previous brand. The shower head and valve connections are more durable and visually appealing. Furthermore, the option of a black color variant adds a touch of elegance, blending seamlessly with the surroundings. Showering under the stars has become a delightful experience, thanks to this exceptional product.

Another aspect worth mentioning is the suitability of this heater for off-grid living. As a resident of British Columbia, I find the Gasland Outdoor Shower Heater to be a game-changer. It allows me to fill my kiddie pool and have a hot tub experience at night, enhancing my off-grid lifestyle.

While I did encounter a few issues with the heater, the company's support team proved to be exceptional. Upon contacting them, they promptly assisted me in troubleshooting the problem. Though the issue persisted, Gasland went above and beyond by fully replacing the heater. Their quick response, kindness, and attentiveness throughout the process were commendable. I am confident that the new heater will perform flawlessly once installed.

I have been using this outdoor hot water heater as my main source of hot water in my RV, and I must say that it works exceptionally well. Contrary to some negative reviews, I have found that it performs efficiently as long as there is sufficient water pressure to maintain a good temperature. I have been using it for almost a month now, using it every two days, and it starts up reliably every time.

One feature that I particularly appreciate is the automatic shut-off when the temperature exceeds 120 degrees Fahrenheit. It provides peace of mind knowing that it will restart itself once the temperature is safe again. I have tested it in various weather conditions, from 40 degrees to the 90s, and it consistently heats the water to my desired temperature.

In terms of propane usage, I am pleasantly surprised by its efficiency. Despite taking long showers (around 20 minutes or longer) two to three times a week, I have barely made a dent in my propane tank. After a month of usage, I am still in the green. It's impressive how this unit manages to provide such a satisfying shower experience, rivaling that of many homes.

The controls are straightforward and easy to get used to. While reading the directions certainly helps, they are intuitive enough that common sense will guide you through the setup process. As long as you install everything correctly and ensure proper ventilation, this hot water heater is worth every penny.

Update: March 2023 – I am pleased to report that this outdoor hot water heater is still going strong even after over a year of use. It has endured all weather conditions while being stored outside (wrapped in a plastic bag when not in use). I have drained it during freezing months and used it periodically throughout the winter, and it continues to perform flawlessly. I highly recommend this unit for its durability and reliability.

If you plan to use this hot water heater off-grid, like I do, you will need a water source and a pump. In my case, I use a 12v water pump, specifically the Eccotemp EccoFlo Diaphragm 12v water pump, which works perfectly. The pump can self-prime up to 30 feet horizontally and 6 feet vertically, making it convenient for accessing water sources. It can be powered by a regular 12v battery or connected to a solar power station.

With the water pressure on the heater turned down low, the pump operates smoothly and consumes around 90 watts of power. It is compatible with average water pressure (around 45psi) found in outdoor faucets, so there is no need to worry about compatibility. The water heats up within 3-4 seconds, and the shower head provides a powerful stream.

For those using well water or rainwater collection, I recommend installing a water filtration system between the pump and the shower to ensure clean water. Overall, this model is more than sufficient for showering and other hot water needs, such as washing dishes. I have even used it for that purpose by cranking up the heat and using a washing up bowl.

The heater being reviewed here is highly praised for its performance and versatility. Users have found that it provides a satisfying shower experience, with the ability to adjust the water pressure according to their preference. The heater is capable of delivering both high and low-pressure showers, with the flame adjusting accordingly. For those seeking a cold shower, simply turning off the gas supply achieves the desired result.

One reviewer mentioned using this heater in an outdoor shower at an ATV mud park and found it to be excellent. The heater produced ample hot water, allowing multiple people to enjoy long showers without any issues. The convenience of starting the heater with just two D batteries and the ease of adjusting the temperature by adjusting the water flow or heat were also highlighted. The portability of the heater was also appreciated, as it can be easily hung from any suitable spot.

The reviewer even mentioned a potential use for this heater during a backwoods jeep adventure, where it could be connected to a boat bilge pump and hose to pump water from a nearby creek. The only drawback mentioned was that the temperature may not go low enough when it's 95 degrees outside, but this was considered a minor concern as the heater still performs exceptionally well in other weather conditions.

In an update provided in April 2019, the reviewer mentioned that the heater is still going strong. They made some modifications to enhance its performance, including replacing the battery pack with a power supply and adding a foot switch and a pump for better control over the water flow. The reviewer was able to shower with less than a gallon of water, thanks to these modifications.

The reviewer also mentioned some issues with the non-standard connections of the heater. The water and gas connections require specific adapters and washers to prevent leaks. Additionally, the gas connection uses British straight threads instead of the standard NPT/MIP taper, which may require additional adapters for certain installations. The water connections also require specific adapters and may not fit standard fittings available at local stores. However, the reviewer noted that the seller provided helpful information on the appropriate adapters to use.

I recently purchased this outdoor water heater for my motorhome and I am extremely satisfied with its performance. As someone who lives in a compact motorhome with a tiny shower, I needed a solution that would provide me with a more spacious shower experience. This water heater exceeded my expectations by delivering endless hot water for long showers. Additionally, the price point of this product is great, making it an excellent investment for RV owners.

One of the standout features of this water heater is its efficiency in propane consumption. It sips propane, and a 5-gallon bottle can last my partner and me for over three months. This not only saves us money but also ensures that we have hot water whenever we need it.

I also decided to incorporate this water heater into a DIY pool heater that I built, and it has been working flawlessly. It consistently provides water output that can reach temperatures as high as 160 degrees Fahrenheit, which is impressive. I appreciate the fact that the machine is not straining at the settings I am using, indicating its reliability and durability.

However, there are a few considerations to keep in mind when using this water heater. Firstly, the manual provided with the product is not very helpful, so be prepared to figure out some of the finer details on your own. Secondly, the water heater is sensitive to both gas pressure and water flow, so it may take some time to adjust these settings correctly. I would recommend purchasing a good regulator for gas pressure and ensuring that there is adequate water flow to prevent any ignition issues.

Another minor inconvenience is that the display is in Celsius, which may require some adjustment if you are used to Fahrenheit. Additionally, the water and gas connectors are not US standard, so you will need to purchase adapters for proper installation.

To enhance the overall experience, I opted to buy better quality shower head and hose attachments, as the ones provided with the water heater were not of the highest quality. However, the unit itself is well-made and durable, ensuring its longevity.

The Eccotemp L5 is a fantastic portable water heater that is perfect for outdoor adventures such as overlanding and camping. It is a versatile and reliable unit that provides hot water for showering and washing dishes, making it a convenient addition to any outdoor setup.

One of the standout features of the Eccotemp L5 is its ability to heat water quickly and efficiently. Even when using the lowest flow and heat settings to conserve water and propane, the water still comes out warm and at a good pressure. For those who prefer hot-hot water, simply adjust the dial to get the desired temperature.

The included accessories and fittings that come with the Eccotemp L5 provide plenty of options for plumbing the unit. This is a significant advantage compared to other brands that may require hard-to-find fittings. With the Eccotemp L5, finding the necessary pipe threads and sizes is easy, as they are readily available at most hardware stores.

The setup process for the Eccotemp L5 is straightforward and hassle-free. It can be mounted in a large case with a 12v water pump, making it self-contained and portable. All you need to do is add water and propane, and you're ready to go. Whether you're going on a solo trip or planning a group adventure, the Eccotemp L5 ensures that hot showers are possible in the wilderness.

While the reviewer mentions that they would have preferred an upgraded unit with the ability to vent the gas outside and keep the unit in the cabin, they are still very happy with the Eccotemp L5. This shows that despite this minor drawback, the overall performance and satisfaction with the unit are high.

The reviewer also shares a unique and creative use for the Eccotemp L5. They repurposed an old bathtub and built a makeshift hot tub using pallets, plywood, and canvas. The unit was mounted inside the tub, ensuring proper installation, and the hot water provided a luxurious bathing experience under the stars. The reviewer expresses their absolute satisfaction and gives the Eccotemp L5 a well-deserved 5-star rating.

I have purchased and used this water heater for my outdoor shower at the flower garden, and overall, I am quite satisfied with its performance. However, there are a few things that potential buyers should be aware of before making a purchase.

Firstly, it is important to have a good understanding of mechanical devices in order to properly install and operate this water heater. If you are not familiar with such things, I would highly recommend reading and following all the instructions carefully.

Additionally, it is worth noting that some of the small plastic components, such as the quick-connect fittings, are not designed to withstand a lot of stress. It is important to hand tighten them just until you feel the rubber seals compress, and be careful not to overtighten them as it may cause damage.

Furthermore, the gas fitting is a crucial part of the water heater and must be installed correctly to prevent any potential hazards. It is essential to ensure that it is properly connected to avoid any fire-related incidents.

In terms of functionality, this water heater works great once you grasp the concept. The digital readout is a useful feature, but it is important to understand that it only displays the current temperature and is not a setting that can be adjusted.

The water flow rate and the temperature control knob on the left are the two factors that determine the water temperature. Increasing the water flow rate will cause the temperature to decrease, while adjusting the temperature control knob will increase or decrease the temperature accordingly.

However, it is crucial to have a steady water supply to maintain a consistent temperature. Fluctuations in water flow rate or water temperature can significantly impact the output of the heater and may result in sudden temperature changes during usage.

In terms of durability, I did encounter a small issue with the ignitor switch after approximately four months of use. However, the customer support team was extremely helpful and guided me through a few tests. Ultimately, they replaced my water heater with a new one, demonstrating their commitment to standing behind the products they sell.

I am extremely impressed with the Gasland portable tankless water heater. This product has exceeded all of my expectations.

Firstly, its versatility is a major advantage. Whether I am using lake water or well water, the heater consistently provides hot water, even when the temperature is as low as 70°F or 21°C. This is particularly beneficial for me as I have a cottage on a northern lake. Additionally, the fact that it can be used with a regular propane tank is fantastic, especially during times when my cottage is off-grid due to storms.

The temperature control is another standout feature of this water heater. With an easy-to-read indicator, I can adjust the temperature to my liking. I consistently have hot water at around 42°C or 108°F, making for a comfortable and enjoyable showering experience.

The ease of installation and use is also worth mentioning. The fittings were simple to attach, and I had no issues using Gardena quick connects with it. The included adapters and wrenches were a thoughtful addition, ensuring a hassle-free setup. The regulator always works flawlessly, and the starting sequence is straightforward if you follow the provided directions.

Durability and longevity are important factors for any product, and this water heater does not disappoint. I have used it for two full seasons, and the Energizer D-Cells that power it have lasted the entire time. Additionally, I have even used a AA-cell replacement adapter without any impact on its functionality.

Maintenance is a breeze with this water heater. It is easy to drain, thanks to the convenient drain plug. This feature, coupled with its overall efficiency, allows me to enjoy virtually limitless hot water and rinse off with ease.

I recently purchased this outdoor shower heater for my cabin at a high altitude of 9200ft. I had been struggling to find a solution that could perform well in these conditions, but this heater has exceeded my expectations. It starts instantly and remains lit even in 35mph winds, which is impressive considering it is only protected on two sides. It also heats water from 41F to 108F in just 35 seconds, which is incredibly fast.

The only downside for off-grid use is that it relies on 110v AC power. However, the power consumption is relatively low at around 200 watts, so I am planning to install a small dedicated inverter to address this issue. Despite this minor inconvenience, I have high hopes for the long-term performance of this heater.

I have now been using this heater for eight months, and it continues to impress me. It has had zero issues and has proven to be extremely reliable. During the past winter, I even melted snow to feed it back into a frozen solid 55-gallon barrel, and it warmed the water from sub-30F to 110F without any problems. The control panel is simple and accurate, and I have abandoned my previous setup of mixing cold water with a temperature regulating valve in favor of directly controlling the temperature through the panel.

Installation was relatively easy and took about an hour. We have low water pressure at only 24 psi, but once we adjusted the flow to keep the pressure up, the device worked perfectly. There is a safety feature that regulates the burner based on water pressure, so maintaining adequate pressure is important. We solved this issue by adding an expansion tank to accommodate the rapidly heating water. The flow rate of the heater is excellent and much faster than I anticipated. We were even able to continuously fill up our jacuzzi, which requires 250 gallons of water, something we were unable to achieve with a standard water heater.
