The Dometic optional heat strip is presented as a supplemental heating solution for recreational vehicles (RVs). Installation involves attaching the heat strip to the air conditioning (AC) unit, often before the unit is fully installed on the RV roof. Operation requires verification of model compatibility and, potentially, additional components such as a controller kit. Users should be aware that the heat strip is designed to remove chill from the air, not to replace a conventional RV furnace, and may take a significant amount of time—between 40 and 60 minutes—to noticeably warm a space. The system’s functionality is dependent on correct wiring and the presence of a heating element, which may need to be purchased separately.
Installation Procedure
The installation of the Dometic heat strip requires careful attention to the order of operations. According to available documentation, the heat strip should be mounted to the AC unit before the AC unit is placed on the RV roof. This is to facilitate easier access and prevent complications during the installation process. The heat strip mounts directly to the ceiling template from below, requiring a slot to be cut through the insulation for the heater cable.
The documentation references three instruction manuals: one for the thermostat guided unit, and one specifically for adding the heat strip to the AC unit. Proper utilization of these manuals is crucial for a successful installation. The process involves securing the components with only a couple of screws.
Operational Characteristics and Considerations
Once installed, the heat strip’s operation differs from a standard furnace system. The fan will activate immediately upon initiating the heat function, circulating air at room temperature before the heat strip reaches operating temperature. This results in a period where cool air is distributed until the heat strip generates sufficient warmth.
Dometic documentation suggests a simple operational procedure: turn the optional heat function on, allow the system to reach the desired temperature, and then turn the optional heat function off. However, the thermostat does not directly control the heat strip’s function. Patience is required, as it can take upwards of 40 minutes to perceive a temperature difference.
Compatibility and Component Requirements
Determining compatibility is a critical first step. While some models may be wired for heat, a heating element may not be installed and must be purchased separately. The documentation indicates that the availability of heat strips varies depending on the specific Dometic AC unit model.
Historically, in 2011, a separate analog controller kit and thermostat were required for proper operation. Current requirements are less clear, with one source noting that a seller did not mention the need for these additional parts. However, the potential need for a more expensive controller kit has been reported by reviewers. Users are strongly advised to consult with a dealer to ascertain the complete component list required for their specific AC unit.
Performance Limitations and User Feedback
The Dometic heat strip is explicitly positioned as a supplemental heat source, not a replacement for a traditional RV furnace. It is designed to remove chill from the air rather than provide substantial heating. Several drawbacks have been noted.
The heat strip’s heating output is relatively low, leading some owners to question its value. It can also generate noticeable noise during operation, potentially detracting from user experience. The lengthy warm-up time—40 to 60 minutes—is another significant limitation.
Some owners have expressed dissatisfaction with the heat strip’s performance, declining to purchase the unit when offered by a dealer. The documentation acknowledges that the heat strip may not be worth the expense and trouble for all users.
Potential Challenges and Troubleshooting
DIY installation can be challenging, and Dometic appears to make it difficult for enthusiasts to install the strip and controller independently. Correct wiring is essential, and a blown fuse or tripped breaker could indicate an electrical issue.
If the heat strip is not producing heat, despite the thermostat being set to “heat,” the unit may lack a heating element. It is also important to verify that the heat strip is correctly wired to the power supply. The documentation emphasizes the importance of consulting with a dealer to understand the complete installation process and component requirements.
Trademark and Copyright Information
The documentation states that all trademarks mentioned within the manuals belong to Dometic Sweden AB, and all rights are reserved. The Mode and Zone buttons are either patented or patent pending.
Conclusion
The Dometic optional heat strip offers a supplemental heating solution for RVs, but its performance is limited and installation can be complex. Users must verify compatibility, potentially purchase additional components, and be prepared for a lengthy warm-up time. The system is best suited for removing chill from the air rather than providing substantial heat, and consulting with a Dometic dealer is highly recommended to ensure a successful installation and operation. The documentation highlights the importance of following installation instructions carefully and understanding the system’s limitations before investing in this supplemental heating option.
