If you’re looking to replace your water heater with a tankless model and wondering whether it can be installed outside, you’ve come to the right place. Installing a tankless water heater outside your home can provide some advantages, but there are a few important considerations to keep in mind first.
In short, tankless water heaters can be installed outside, but only if they are specifically designed for outdoor installation. You’ll need to choose a model rated for outdoor use and take some extra installation precautions.
What is a Tankless Water Heater?
A tankless water heater, also known as an on-demand water heater, is a modern and energy-efficient alternative to traditional water heaters. Unlike conventional water heaters that store and continuously heat a large volume of water in a tank, tankless water heaters heat water directly as it passes through the unit, providing hot water on demand.
Basic Function
The basic functioning of a tankless water heater involves a heat exchanger that quickly heats the water as it flows through the system. When a hot water tap is turned on, cold water enters the unit and passes through the heat exchanger.
The heat exchanger rapidly heats the water to the desired temperature using either gas burners or electric heating elements.
As the water heats up, it is delivered to the faucet or showerhead in a constant and continuous stream. This eliminates the need for a storage tank, resulting in a more compact and space-saving design.
Pros and Cons of Tankless Models
There are several advantages to installing a tankless water heater. Firstly, they provide an endless supply of hot water, so you never have to worry about running out during long showers or when multiple faucets are being used simultaneously.
This can be especially beneficial for larger households or commercial properties.
Additionally, tankless water heaters are more energy-efficient compared to traditional models. Since they only heat water when it is needed, they eliminate the energy losses associated with storing hot water in a tank. This can result in significant cost savings on energy bills over time.
On the other hand, it is important to consider the potential drawbacks of tankless water heaters. The upfront cost of purchasing and installing a tankless unit is generally higher than that of traditional water heaters. However, the long-term energy savings can help offset this initial investment.
Furthermore, the flow rate of tankless water heaters may be limited, especially in colder climates or when multiple hot water outlets are being used simultaneously. It is crucial to select a tankless unit that is appropriately sized for the intended application to ensure sufficient hot water supply.
Can Any Tankless Unit Be Installed Outside?
Many homeowners wonder if they can install a tankless water heater outside their homes. While tankless water heaters are typically designed for indoor installation, there are options available that are specifically designed for outdoor use.
Let’s explore whether any tankless unit can be installed outside and the considerations you need to keep in mind.
Outdoor Rating is Crucial
When considering an outdoor installation, it is crucial to choose a tankless water heater that has an outdoor rating. This means that the unit is specifically designed to withstand the elements and can safely operate in outdoor conditions.
Outdoor-rated tankless water heaters are built with weather-resistant materials that can resist rust, corrosion, and other outdoor factors.
It is important to note that not all tankless water heaters have an outdoor rating. Some models are designed solely for indoor use and may not be suitable for outdoor installation. Therefore, it is essential to check the manufacturer’s specifications and recommendations before purchasing a unit for outdoor installation.
Other Outdoor Installation Considerations
Aside from choosing a tankless water heater with an outdoor rating, there are other considerations to keep in mind when installing it outside:
- Location: The unit should be installed in a location that is protected from direct sunlight, extreme temperatures, and other environmental factors.

- Freeze Protection: If you live in an area with freezing temperatures, it is essential to protect the unit from freezing by using appropriate insulation or installing it in a frost-free location.
- Gas and Electrical Connections: Ensure that the necessary gas and electrical connections are available at the chosen installation location.
By considering these factors and selecting a tankless water heater with an outdoor rating, you can enjoy the benefits of an efficient and space-saving water heating solution outside your home. Always consult with a professional plumber or follow the manufacturer’s guidelines for a safe and proper installation.
