When it comes to tankless water heaters, one of the most common questions homeowners ask is whether they can use an indoor tankless water heater outside. The answer to this question is not a simple yes or no, as it depends on various factors, including the type of tankless water heater, the climate, and the installation requirements.
Understanding Tankless Water Heaters
Before we dive into the specifics of using an indoor tankless water heater outside, it’s essential to understand how tankless water heaters work. Tankless water heaters, also known as on-demand water heaters, heat water only when it’s needed, unlike traditional tank-style water heaters that constantly heat and reheat water in a storage tank.
Tankless water heaters are available in various types, including gas-fired, electric, and heat pump models. They are designed to provide a continuous supply of hot water, and they are generally more energy-efficient than traditional tank-style water heaters.
Indoor vs. Outdoor Tankless Water Heaters
Tankless water heaters are designed for either indoor or outdoor installation, and each type has its unique characteristics and requirements. Indoor tankless water heaters are designed to be installed inside a building, typically in a basement, garage, or utility room. They are usually smaller and more compact than outdoor models and are designed to provide a high level of efficiency and performance in a controlled environment.
Outdoor tankless water heaters, on the other hand, are designed to be installed outside a building, typically on an exterior wall or on a freestanding platform. They are usually larger and more robust than indoor models and are designed to withstand the elements, including extreme temperatures, wind, and weather.
Can You Use an Indoor Tankless Water Heater Outside?
Now, let’s get back to the question at hand: can you use an indoor tankless water heater outside? The answer is, it’s not recommended. Indoor tankless water heaters are designed to operate in a controlled environment, and they are not built to withstand the elements.
If you install an indoor tankless water heater outside, you may encounter several problems, including:

Alternatives to Using an Indoor Tankless Water Heater Outside
If you need to install a tankless water heater outside, there are several alternatives to using an indoor model. Here are a few options:
- Outdoor tankless water heaters: These units are specifically designed for outdoor installation and are built to withstand the elements. They are available in various types, including gas-fired, electric, and heat pump models.
- Weather-resistant enclosures: These enclosures are designed to protect indoor tankless water heaters from the elements and can be installed outside. However, they may not provide the same level of protection as an outdoor tankless water heater.
Benefits of Outdoor Tankless Water Heaters
Outdoor tankless water heaters offer several benefits, including:
- Increased durability: They are built to withstand the elements and can provide years of reliable service.
- Improved performance: They are designed to operate efficiently in outdoor environments and can provide a high level of hot water.
- Reduced maintenance: They require less maintenance than indoor tankless water heaters installed outside and are less prone to repairs and replacements.
Conclusion
In conclusion, while it may be tempting to use an indoor tankless water heater outside, it’s not recommended. Indoor tankless water heaters are designed to operate in a controlled environment, and they are not built to withstand the elements. If you need to install a tankless water heater outside, it’s best to use an outdoor model or a weather-resistant enclosure. By choosing the right type of tankless water heater for your needs, you can ensure a safe, efficient, and reliable hot water supply.
Final Thoughts
Before making a decision, it’s essential to consider the following factors:
- Climate: If you live in an area with extreme temperatures, wind, or weather, an outdoor tankless water heater may be the best option.
- Installation requirements: Make sure to follow the manufacturer’s installation requirements and local building codes.
- Warranty and maintenance: Consider the warranty and maintenance requirements of the unit and ensure that you understand the terms and conditions.
By considering these factors and choosing the right type of tankless water heater for your needs, you can ensure a safe, efficient, and reliable hot water supply.
Can I install an indoor tankless water heater outside?
