Things to Know Before Buying Outdoor Tankless Water

Before buying an outdoor tankless water heater, there are several important factors to consider. These units provide on-demand hot water and are well-suited for outdoor installations, such as in gardens, patios, or near hot tubs. Here are some key things to know before making your purchase:

Outdoor Installation:

  • Outdoor tankless water heaters are designed specifically for outdoor use. They are exposed to the elements, so ensure you have an appropriate outdoor location with proper ventilation for installation.

Fuel Type:

  • Tankless water heaters can be powered by electricity, natural gas, propane, or even solar energy. Choose a fuel type that aligns with your energy source availability and cost preferences.

Flow Rate and Capacity:

  • Determine your hot water needs based on the number of appliances and fixtures that will use hot water simultaneously. Select a tankless water heater with the appropriate flow rate and capacity to meet your household's demands.

Temperature Rise:

  • Consider the desired temperature rise, which is the difference between the incoming cold water temperature and the desired hot water temperature. This affects the unit's performance and sizing.

Energy Efficiency:

  • Look for an energy-efficient model. Tankless water heaters are generally more efficient than traditional tank-style heaters because they only heat water when needed, reducing standby heat loss.

Location and Altitude:

  • Your geographic location and altitude can impact the performance of your tankless water heater. Some models are designed for high altitudes, so check the manufacturer's specifications.

Installation Cost:

  • Factor in installation costs, including the need for a gas line or electrical work, venting (if applicable), and plumbing modifications. Professional installation is often required.


  • Check the manufacturer's warranty for coverage and duration. A longer warranty can provide peace of mind and potentially save on repair costs.


  • Tankless water heaters require periodic maintenance to descale and clean the heat exchanger. Consider the ease of maintenance when selecting a model.

Temperature Control:

  • Choose a unit with precise temperature control to ensure your water is delivered at the desired temperature.

Safety Features:

  • Look for safety features like freeze protection, overheat protection, and flame failure devices, especially if you live in an area with cold winters.


  • Ensure that the tankless water heater is certified by relevant safety and efficiency organizations, such as UL (Underwriters Laboratories) or ENERGY STAR.

Local Codes and Regulations:

  • Check local building codes and regulations to ensure compliance with outdoor water heater installations, venting requirements, and safety standards.

Accessories and Compatibility:

  • Consider any additional accessories you may need, such as a remote control, outdoor cover, or isolation valves for easy maintenance.

User Reviews:

  • Read user reviews and seek recommendations to gain insights into real-world performance and reliability from other customers.

In Conclusion

By carefully considering these factors and conducting thorough research, you can select the right outdoor tankless water heater that meets your hot water needs and performs well in your outdoor environment. It's also important to have the unit professionally installed and regularly maintained to ensure optimal performance and longevity.
