The good news is that in many cases, it is indeed possible to install a tankless water heater horizontally. However, there are a few considerations to keep in mind before proceeding with a horizontal installation.
Model-specific requirements: Different tankless water heater models may have specific requirements outlined by the manufacturer. These requirements often include guidelines on the positioning and orientation of the unit during installation. Each model’s instruction manual should always be consulted to ensure compliance with any specific requirements.
Venting system: Proper venting is crucial to ensure the safe and efficient operation of a tankless water heater. Some models may require vertical venting, while others may allow for horizontal venting. It is essential to check the manufacturer’s guidelines to determine whether horizontal venting is allowed for the particular model you are considering. If horizontal venting is permitted, ensure that all necessary venting components are properly installed and comply with local building codes.
Space availability: One major consideration when installing a tankless water heater horizontally is the availability of sufficient space. These units are generally compact and designed for wall-mounting. Installing a tankless water heater horizontally may require additional space compared to vertical installations. Make sure to measure the available space and verify if the intended installation area can accommodate a horizontal unit before proceeding.
Maintenance accessibility: Another aspect to consider when contemplating a horizontal installation is the accessibility for maintenance and service. Tankless water heaters may require periodic cleaning and servicing, and a horizontal unit should be easily accessible for such tasks. Ensure that the chosen location allows for easy access to the unit for maintenance purposes.
Professional Installation
Given the complexities involved in correctly installing a tankless water heater, it is highly recommended to hire a professional plumber or HVAC technician. These professionals have the necessary knowledge and expertise to install the unit according to the manufacturer’s guidelines, local building codes, and industry standards. By opting for professional installation, you can gain peace of mind knowing that your tankless water heater is installed correctly and will operate efficiently.
In summary, while it is sometimes possible to install a tankless water heater horizontally, several factors need to be taken into account. These include model-specific requirements, venting systems, available space, and accessibility for maintenance purposes. It is crucial to consult the manufacturer’s guidelines and consider hiring a professional to ensure a safe and efficient installation. By doing so, you can enjoy the benefits of a tankless water heater while minimizing the potential issues associated with an improper installation.
