Finally, it's important to choose a reputable brand and model of portable tankless water heater. Look for heaters that have been tested and certified by recognized safety organizations, such as UL or CSA, and read reviews from other users to ensure that the heater is reliable and safe to use.

How does a portable tankless water heater compare to a traditional tank water heater?
A portable tankless water heater is a more energy-efficient and space-saving option compared to a traditional tank water heater. Tankless heaters only heat water on-demand, which means they consume less energy as they don't have to constantly heat and reheat water to maintain a certain temperature. In contrast, traditional tank heaters store and heat a large amount of water, which can result in wasted energy and higher utility bills.
Moreover, a portable tankless water heater is more compact and can be easily moved from one location to another, making it a convenient option for outdoor activities, camping, or small apartments. In contrast, traditional tank heaters are bulky and require a significant amount of space to install.
However, it's worth noting that portable tankless water heaters have lower flow rates than traditional tank heaters, which means they may not be suitable for large households with high water demands. Additionally, tankless heaters can have a higher upfront cost and may require professional installation, which can add to the overall expense.
How much does a good portable tankless water heater cost?
The cost of a good portable tankless water heater can vary depending on the brand, features, and size. On average, a high-quality unit can cost anywhere from $200 to $600. However, it is important to note that the cost may increase for units with advanced features such as digital temperature control, multiple burner options, and higher flow rates. Additionally, some brands may offer warranties or additional customer support services which can also increase the overall cost. It is recommended to research and compare different brands and models before making a purchase to ensure that you are getting the best value for your money.

What is the best way to install a portable tankless water heater in an RV?
Installing a portable tankless water heater in an RV can be a great way to have a constant supply of hot water while on the road. The best way to install a portable tankless water heater in an RV is to first select a location where it can be easily installed and accessed. This location should have proper ventilation and should be close to both the water supply and the propane tank.
Once you have selected the location, you can begin the installation process. First, connect the water supply to the inlet of the water heater. Then, connect the propane supply to the gas inlet of the water heater. Be sure to use a gas regulator to control the flow of propane.
Next, install the exhaust vent to ensure proper ventilation. The vent should be installed vertically and should be at least one foot above the roofline of the RV. Finally, install the showerhead and faucet in the desired location and test the water heater to ensure it is working properly.
It is important to follow the manufacturer's instructions carefully when installing a portable tankless water heater in an RV. If you are not comfortable with the installation process, it is recommended that you seek the assistance of a professional.
What size tankless water heater should I get for my portable needs?
The size of tankless water heater you need for your portable needs will depend on several factors. First, you need to consider the flow rate of the unit, which is measured in gallons per minute (GPM). This will determine how much hot water the unit can produce at any given time.
Secondly, you need to consider the temperature rise that you require. This is the difference between the temperature of the incoming water and the temperature of the water you want to use. The greater the temperature rise, the larger the unit you will need.
Lastly, you need to consider the fuel source for your tankless water heater. If you will be using propane, you will need a larger unit than if you are using electricity.
As a general rule, a portable tankless water heater with a flow rate of 1.5 GPM should be sufficient for most portable needs. However, it is always best to consult with a professional to determine the exact size and specifications that will meet your specific needs.
