What is the Best Outdoor Tankless Water Heater/ Who This is for
Outdoor tankless water heaters have all the efficient and high-performance features of any other domestic liquid heating system. However, what sets an outdoor tankless unit apart from other types is weatherproofing.
Since an outdoor unit is at the mercy of the elements, it should have adequate protective mechanisms to guarantee its optimal functioning. It can withstand adverse weather conditions, including strong winds, freezing temperatures, severe storms, and other forces of nature.
The best outdoor tankless unit is suitable for anyone who wants an efficient fluid heating system in their home, backyard, or anywhere they decide to go. It is perfect for off-grid enthusiasts, campers, anglers, road trippers, hobbyists, and more. A tankless heater unit is always a wise choice whenever there is a need for a hot liquid supply.
How Do Outdoor Tankless Water Heaters Work
Tankless water heaters work like any other liquid heating device. Inside the unit are tubes that run through a burner or heating element and a heat exchanger.
An intake port receives cold liquid that passes through the heating element. As the fluid moves through the internal pipes, heat transfers to the liquid and increases its temperature. The fluid moves out of the heater unit and to your plumbing line.
There are two heating options for tankless water heaters. One uses natural gas or propane, while the other uses electricity. An electric tankless water heater connects to your electric supply that powers the heating element. On the other hand, gas tanks supply fuel to the burner.
Outdoor Tankless Water Heater Buying Guide
Choosing the best outdoor tankless water heaters is not complicated. One only needs to ask a few questions to determine the correct tankless unit for the house.
Portable or Fixed?
It would be best to ask yourself whether to buy a portable unit or one that you can fix permanently outside your house.
Most outdoor tankless water heaters are portable devices. One can bring a unit to the campgrounds and never worry about a cold shower ever again. A handy product is suitable for people who love to travel with their families. This unit is also ideal for backyard activities, such as bathing pets, cleaning the garage, and more. The downside to these tankless water heaters is their low GPM rating.
On the other hand, a fixed unit is suitable for homes that want their heating device outside the house for safety concerns. These water heaters often run on natural gas. These types also provide higher GPM ratings for optimum consumption.
Electric or Gas?
Should you pick an electric tankless water heater? Or is a propane or NG product more appealing? In general, a propane-powered unit is more cost-effective in the long run because of its lower fuel unit price compared to electricity. However, a fuel-powered product is often more expensive at the onset.
In determining the correct size of tankless water heater to buy, you should assess two things. First, consider how many gallons flow through each of your fixtures and appliances per minute. For example, a kitchen faucet may have a GPM of 1, while a showerhead can have 2.5 GPM.
If you have three faucets and one bathroom, it is safe to assume that about 5.5 GPM is needed when your fixtures are opened simultaneously. As such, the right size of the tankless water heater product is 5.5 GPM.
Second, consider the groundwater temperature and your ideal temperature. Determine the difference between the two to know the temperature rise you need from your outdoor tankless heater. If your intake temperature is 50 degrees Fahrenheit and you want a 110-degree shower, the temperature rise you seek is 60 degrees Fahrenheit.
Hence, you should pick an outdoor tankless heater with 5.5 GPM at a 60-degree rise.
Some manufacturers require expert installation for their products, lest you void their warranty. You may want to read tankless water heater reviews to understand whether installing the product yourself is worthwhile or not.
In general, installing tankless electric water heaters is more straightforward than installing gas models.
Reading outdoor tankless water heater reviews can give you an idea about the real-life warranty of a product you wish to buy. It is worth noting that some companies offer 10 to 20 years’ warranty, while others may only provide 1 to 2 years. Some brands may even fail to honor their warranty.
Frequently Asked Questions
Who makes the best outdoor tankless water heater?
Rinnai and Rheem are two brands that make the top-rated outdoor tankless water heaters. They have excellent weather protection, including advanced freeze protection technology.
Among the heaters we reviewed, FORUEE makes the best propane outdoor tankless water heater. It has the same advanced freeze protection as Rinnai and Rheem heaters and a few other technological features that outperform other brands.
Other notable brands include Camplux, EccoTemp, Noritz, GASLAND, EZ Tankless, Thermomate, VIVOHOME, and Botabay.
What size outdoor tankless water heater do I need?
Two factors play a role in determining the correct size of an outdoor tankless water heater: temperature rise and flow rate. To do this, you need to do a little math.
- Determine how many gallons per minute (GPM) your fixtures use at maximum. For example, a showerhead may run at 2.5 GPM, and a faucet may have a 0.75 GPM flow rate. The total is 3.0 GPM.
- Determine how hot you want your fluid to be and compare it with your groundwater temperature. For example, you may like a temperature of 110 degrees Fahrenheit. However, your groundwater temperature is 60 degrees Fahrenheit.
Using the information above, you will need a tankless heater capable of raising the liquid temperature by 50 degrees Fahrenheit with a minimum flow rate of 3.0 GPM. Take note that the size computation presupposes you have someone using the shower and another person using the faucet simultaneously.
If you have two people using the shower simultaneously, you will need a tankless heater size capable of delivering 5 GPM (2.5 GPM shower x 2).
How to install an outdoor tankless water heater.
One should always check the local plumbing codes and guidelines before installing any outdoor tankless heater. One should also check the outdoor tankless unit for brand and model-specific installation instructions and prepare the materials and tools. Here are the steps.
- Decide where to mount the outdoor tankless unit and turn off the main water supply line.
- Cut a section of the water line to connect water fittings going to and from the best outdoor tankless unit.
- Mount your new outdoor tankless heater and connect the water fittings and pipes. Ensure the main water line connects to the heater’s cold water intake port. Your water distribution line connects to the heater’s hot water outlet port.
- If one is installing a gas-powered tankless unit, one needs to connect the gas pipe to the tankless heater. Tighten and secure all connections.
- Turn on the main water supply line and check your work for leaks.
- Turn on the gas and the outdoor tankless unit.
- Set the water heater to the desired temperature.
How to keep an outdoor tankless water heater from freezing.
High-end outdoor tankless water heaters already have a built-in freeze protection feature. These products activate their antifreeze mechanisms when the temperature drops to a predetermined level. There is no need to take additional steps to prevent a frozen water heater item.
An excellent example of such a product is the Rinnai outdoor tankless water heater. This product features ceramic heaters integrated into its heat exchanger, water line, and internal parts. One can also see a similar freeze protection design in a Rheem outdoor electric tankless water heater.
If the product does not have this feature, one can observe the following measures:
- Install your water heater in a warm place and away from cold drafts.
- One should consider installing a recirculation system.
- Run a small amount of hot water through your system.
- Wrap the pipes and valves with a pipe heating cable with a built-in thermostat.
- Drain and winterize your outdoor tankless water heater.
How often do you need to descale an outdoor tankless water heater?
One can descale a tankless water heater product every six to 24 months, depending on the groundwater hardness level in the house. The more hardness minerals present in your liquid, the more frequent the descaling is.
As such, if one lives in an area where groundwater hardness levels exceed 180 mg/L (equivalent to 180 ppm or 10.5 grains/gallon), one may have to descale the outdoor tankless unit as often as once every five to six months.
One may also have to descale the tankless unit once every 18 to 24 months if the groundwater hardness level is <60 PPM or <3.5 GPG.
We recommend installing a whole-house water softener if you have high groundwater hardness levels to ease the burden on your tankless water heater. A conditioner can also be an excellent option if you do not like frequent softener recharging.
Do outdoor tankless water heaters run out of hot water?
No, an outdoor tankless unit does not run out of hot liquid. However, it would be best to choose the correct size of a tankless heater.
For example, let us say you have an appliance with a maximum flow of 5 GPM and an 80-degree Fahrenheit temperature rise. This tankless water heater will never run out of hot liquid if you only use no more than 5 GPM at a time. If you use more than that, there is a chance the appliance may not provide you with your preferred temperature.
The best outdoor tankless water heater stands up to the elements without sacrificing liquid heating performance, energy efficiency, and cost savings. It can be a portable device you can bring to your adventures or a fixed appliance delivering consistently hot water to your home.
Getting the right tankless water heater for outdoor use makes perfect sense for people who want a safer yet equally efficient water heating system.
