What is an outdoor tankless water heater? 🤔
It is an efficient way to supply hot water for your outdoor needs. Tankless water heaters provide instant hot water and last longer than traditional tank-style units, saving you energy and money.
Features 🧩
Outdoor tankless water heaters offer a variety of features to meet the needs of different users. Here’s a look at some of their most popular features:
| 📝 Efficient Heating: Most water heaters can provide hot water on demand, meaning they only need to heat the amount of water that will be used instead of constantly keeping a large tank full. This helps save energy and reduce costs. |
| 📝 Space-Saving Design: They are much smaller than traditional tanks, allowing them to fit in tighter spaces or even outdoors. In addition, many models don’t require additional venting as some tank-type models do. |
| 📝 Long Life Span: Tankless heaters generally last longer than their traditional counterparts because there is no lining or anode rod inside the unit which can corrode over time due to hard water deposits. |
| 📝 Easy Installation: Many heaters are easy to install and require no special tools or expertise. They can often be mounted directly on an outside wall or in the garage. |
| 📝 Temperature Control: Most models have adjustable temperature settings, allowing users to set their desired temperature for hot water usage throughout the home. This helps make sure everyone gets the perfect shower experience every time! |
Benefits 🤩
Outdoor tankless water heaters offer an array of benefits for homeowners looking to upgrade their heating systems.
- 💥 These types of water heaters are compact and efficient, meaning they can be easily installed in areas with limited space.
- 💥 Additionally, since they only heat water on demand, tankless models can reduce energy costs significantly when compared to traditional tank-style units.
- 💥 These systems also boast a much longer lifespan than their competition as well, typically clocking in at around 20 years while a standard tank-style heater may only last half that time.
- 💥 Finally, these systems are much safer than traditional units because there is no standing water sitting in the tanks waiting for use – meaning that the risk of contamination or accidental scalding from hot tap water is drastically reduced.
Important to know ⚡
➡️ First, it’s important to understand how tankless water heaters work.
- ⚙️ Basically, they utilize a natural gas burner or electric element to rapidly heat incoming cold water as it passes through a series of internal heating coils or elements. As the hot water rises up and out of the unit, fresh cold water is continually entering through the supply line and being quickly heated by the burner or elements. The result is continuous hot water with no waiting for a tank to fill up and reheat.
🔍 When selecting the heater, there are three main components you should consider: power or energy source, flow rate (how much water can be heated at once), and efficiency rating.
- 🔥 Electric models are typically more affordable than gas models but require higher flow rates for efficient operation.
- 🔥 Gas models generally have higher flow rates and offer better overall performance, but they cost more upfront and use natural gas which may not be available in all areas.

How to protect it from freezing? ❄️
Outdoor tankless water heaters are at risk of freezing in winter months.
- 🔷 To protect your water heater from freeze damage, you should make sure it is insulated properly and has adequate drain line protection.
- 🔷 You can also install a recirculation loop to keep the water inside the pipes warm, or a freeze-sensing thermostat that will turn on when the temperature drops below a certain level.
- 🔷 Additionally, you can use foam insulation to cover the exposed piping and add an extra layer of protection against cold weather.
👍 By following these steps, you can ensure your heater is protected from freeze damage throughout the year.

I’m seeking advice on how to properly care for my outdoor tankless water heater during this freeze. Last year, I made sure to drain the unit since I anticipated a prolonged period of freezing temperatures. However, this time around, it seemed like the freeze would last for less than 24 hours each day, so I didn’t empty the tank. Instead, I took measures to insulate it by wrapping it with fabrics and plastic. I’m unsure if I should periodically turn on the hot water to prevent the coils from freezing completely. I’m also wondering if keeping the pilot light on is sufficient to keep the water in the coils from freezing. Perhaps it’s still a good idea to drain the tankless water heater altogether?
I have come up with a solution. We are scheduling our dishwasher and washing machine to run overnight using a delay feature, ensuring a continuous flow of hot water throughout the house. However, I still worry about the times when we cannot trigger hot water every hour or so. This anxiety has been causing sleepless nights, so I’ve decided to get up periodically to run the hot water during those intervals. It may disrupt my sleep, but it gives me peace of mind and helps alleviate the concern of potential issues with the tankless water heater.
To provide additional insulation, I wrapped a blanket around the unit, making sure to leave the top vent uncovered. Furthermore, I’ve taken extra precautions by running a slow stream of warm water from a faucet located at the farthest side of my house. While I understand that it’s unlikely for the weather to get cold enough to impact the unit, I prefer to be overly cautious, especially after having it replaced last February.
I want to clarify that I’m not a professional plumber, but I do have firsthand experience with an outdoor tankless water heater. During freezing temperatures, one effective method to prevent freezing and bursting is to keep the hot water tap running. Having a constant flow of water through the heater unit helps maintain enough warmth to prevent freezing. To start, you can try dripping the hot water tap, and if you notice the drips slowing down, increase the flow by opening the tap further. Before going to bed, it’s important to check if the water is still dripping or streaming. Some sources suggest using the faucet that is farthest from the incoming pipe for this purpose. It’s worth noting that the flowing water may not be enough to ignite the heater, which is perfectly fine. The objective is to ensure that water continues to flow through the unit and avoid freezing. The water flowing from the main pipe, which is usually warm enough, helps prevent freezing in the unit. As long as this flow is maintained, the tankless water heater should remain unaffected during this period.
I’m interested in hearing about others’ experiences with outdoor tankless water heaters. I currently reside in Houston and I’m considering the idea of relocating my traditional tank water heater outside and replacing it with an outdoor tankless unit. My main objective is to free up space within the house. I would greatly appreciate any opinions or insights from those who have already made this switch.
I would like to offer a reminder to you. Once you have it installed, it’s important to flush it out on a semi-regular basis. This helps prevent scale buildup that could potentially enter the water lines and lead to faucet clogs. By implementing a flushing routine, you can ensure the longevity and optimal performance of your tankless water heater while keeping your water lines clear and free from any potential obstructions.
I own a Camplux Enjoy Outdoor Life CM264-NG and find the idea of installing exterior-mounted tankless units rather than indoor units to be fantastic. It offers significant space-saving benefits by eliminating the need for a traditional tank water heater within the floor plan. Another advantage is that exterior tankless water heaters can be vented directly into the atmosphere, eliminating the need for extensive vent piping and making the installation process easier. However, it’s important to note that one potential drawback is that the proposed location for the tankless water heater may not have the necessary utilities readily available, such as hot water lines, cold water lines, gas lines, and dedicated electrical plugs. As a result, there will be additional costs involved in installing these essential components.
What water heaters brand is most reliable?
I have been using a Rinnai V Series HE Tankless Hot Water Heater for the past 8 years without experiencing any issues. The frequency of cleaning or decalcifying the unit depends on the quality of your water. In my case, I didn’t have a recirculating feature at the time of installation, but I do wish I had chosen a model with that feature. The dealer needs to understand your specific needs to recommend the correct size of the tankless water heater. One reason I would prefer a recirculating feature is for those occasional times when I need hot water for the washing machine. Since newer clothes washers use water in small bursts, it doesn’t trigger enough flow or move enough volume to get hot water to our laundry room, which is located farthest away from the heater.
I have personally found that Rinnai RL Series HE+ Tankless Hot Water Heater would be a good choice. Overall, considering factors such as cost, ease of installation, and long-term performance, I recommend this tankless water heater.
In my opinion, the Rheem RTG-84XLN-1 Tankless Water Heater is a high-quality product. Overall, it’s important to carefully consider the cost, warranty options, and potential installation requirements when choosing between different options for your water heater.
