Tankless water heaters have become increasingly popular in recent years due to their energy efficiency and convenience. But can you install a tankless water heater outdoors? In this article, we’ll explore the benefits and drawbacks of outdoor tankless water heaters, as well as the key considerations to keep in mind when choosing and installing one.
Introduction
Tankless water heaters are an excellent choice for homeowners looking to save energy and space. They are more energy-efficient than traditional tank-style water heaters because they only heat water on demand. However, when considering installing a tankless water heater, one question that often arises is whether it can be installed outdoors.
In this article, we will explore the benefits and drawbacks of an outdoor tankless water heater, as well as the key considerations and installation process involved.
Benefits of an Outdoor Tankless Water Heater
Installing a tankless water heater outside your home can offer several benefits. Firstly, it frees up space inside your home. Traditional tank-style water heaters can take up a lot of room, especially if you have a small home. Installing an outdoor tankless water heater can free up that space, giving you more storage or living area inside your home.
Secondly, an outdoor tankless water heater can reduce the risk of water damage. If a traditional tank-style water heater leaks, it can cause significant damage to your home’s interior. An outdoor tankless water heater eliminates that risk because it is installed outside the home.
Finally, outdoor tankless water heaters are more energy-efficient than their indoor counterparts. Installing an outdoor tankless water heater means that the unit is not competing with other appliances or systems inside your home for air supply. This can result in better performance and efficiency.
Drawbacks of an Outdoor Tankless Water Heater
While there are several benefits to installing an outdoor tankless water heater, there are also some drawbacks to consider. One of the most significant drawbacks is that outdoor tankless water heaters may not be suitable for colder climates. If the temperature drops below freezing, the water in the pipes leading to the heater can freeze, causing the unit to malfunction or even break.
Secondly, installing an outdoor tankless water heater may be more expensive than an indoor unit. Outdoor units require additional materials, such as weather-resistant housing and ventilation, which can add to the installation cost.
Finally, an outdoor tankless water heater may be more difficult to access for maintenance or repairs. If the unit is installed in a hard-to-reach area, it can be more challenging to perform routine maintenance or fix any issues that arise.
Key Considerations for Outdoor Tankless Water Heaters
Before deciding to install an outdoor tankless water heater, there are several key considerations to keep in mind.
Climate
The climate in your area is one of the most important factors to consider. If you live in an area with mild winters and little to no risk of freezing temperatures, an outdoor tankless water heater may be a good option. However, if you live in an area with harsh winters, you may want to consider an indoor unit or other options.
Size and Capacity
The size and capacity of the outdoor tankless water heater are also crucial considerations. You’ll want to make sure the unit is appropriately sized to meet your household’s hot water demands. If the unit is too small, it may not be able to provide enough hot water for your needs, while a unit that is too large can result in wasted energy.
Gas vs. Electric
Another consideration is whether to choose a gas or electric outdoor tankless water heater. Gas units are often more energy-efficient and can provide a higher flow rate, making them ideal for larger households. Electric units, on the other hand, are often less expensive to purchase and install, making them a good choice for smaller households.
Ventilation
Proper ventilation is essential when installing an outdoor tankless water heater. The unit needs to be adequately vented to ensure safe operation and prevent the buildup of carbon monoxide. A professional installer can help ensure that the unit is correctly vented to meet local codes and regulations.
Access and Maintenance
Finally, it’s essential to consider the unit’s accessibility for maintenance and repairs. While an outdoor unit can free up space inside your home, it may be more difficult to access for routine maintenance. It’s crucial to ensure that the unit is installed in a location that is easy to access and that any necessary maintenance can be performed safely and efficiently.
Installation Process for an Outdoor Tankless Water Heater
Installing an outdoor tankless water heater requires careful planning and professional installation. Here are the basic steps involved in the installation process:
- Choose the right location: The unit should be installed in a location that is protected from the elements and has adequate ventilation.
- Install the necessary equipment: Depending on the unit’s requirements, additional equipment may be needed, such as a weather-resistant housing, a vent pipe, and a gas line.
- Connect the unit: The unit must be connected to the water supply and the gas or electric source.
- Test the unit: The installer should test the unit to ensure that it is functioning correctly and that all safety features are working correctly.
- Schedule regular maintenance: To ensure the unit’s optimal performance and longevity, regular maintenance is essential. This can include flushing the unit’s system to remove any mineral buildup and inspecting the unit for any signs of wear or damage.
Conclusion
In conclusion, installing an outdoor tankless water heater can offer several benefits, such as freeing up space inside your home and reducing the risk of water damage. However, there are also some drawbacks to consider, such as the potential for freezing in colder climates and the additional installation costs. It’s essential to consider the key factors involved, such as climate, size and capacity, gas vs. electric, ventilation, and access and maintenance, when choosing and installing an outdoor tankless water heater.
