The Dometic Stowaway Flow Switch is a critical device designed to ensure proper water flow in marine air conditioning systems. This component is an essential safeguard for preventing system overheating, a common issue when water flow is interrupted due to clogs, pump failure, or air pockets. By actively monitoring water flow, the switch protects your system’s compressor and ensures consistent cooling in marine environments.
How the Flow Switch Functions
At its core, the Dometic flow switch operates by using a sensor to monitor water movement through the system. This flow-sensitive mechanism determines whether water is flowing at the required rate. When the flow drops below a preset threshold, the switch sends a signal to shut down the compressor. This prevents damage to the system caused by overheating.
The flow switch works seamlessly with water pumps, filters, and heat exchangers, ensuring all components function efficiently. For self-contained marine air conditioning systems, such as those in the Dometic Stowaway series, this level of precision is essential for optimal performance.
Different Types of Marine Air Conditioning Systems
Choosing the right system depends on your vessel’s size, layout, and your personal needs. Here are the main types:
Self-Contained Units
Perfect for small boats, these compact units combine all components in one system. They are affordable, easy to install, and ideal for boats with limited space.
Split Systems
Split systems separate the compressor from the evaporator, making them quieter than self-contained units. They are a great choice for medium to large boats.
Chilled Water Systems
These systems are designed for larger yachts. They use chilled water to cool the air and can provide zoned temperature control for multiple areas.

How to Choose the Right Air Conditioner for Your Boat
There are a few important factors to consider when selecting a marine air conditioning unit:
Boat Size
Start by measuring your boat’s interior space to determine the cooling capacity you need. Air conditioners are rated in BTUs (British Thermal Units), which indicate their cooling power. Choosing a system with the correct BTU rating is essential for efficient cooling; an undersized unit may struggle to maintain comfort, while an oversized one could waste energy.
Power Supply
Check your vessel’s power system to confirm it is compatible with the air conditioner. Many marine AC units operate on specific voltage and frequency requirements, such as 115V or 230V at 50/60 Hz. Ensuring compatibility will prevent electrical issues and allow the system to function smoothly.
Installation Space
The space available for installation is another critical consideration. Some models are specifically designed for tight areas, making them ideal for smaller boats. Be sure to measure the area where the unit will be installed and choose a model that fits comfortably without compromising ventilation.
Climate Needs
Lastly, consider the climate where you’ll be using your boat. If you frequently sail in warmer or tropical regions, opting for a higher-capacity unit can ensure reliable cooling even in intense heat. Conversely, a smaller unit may suffice for cooler climates or occasional use.
Marine Air Conditioning: A Must-Have for Boating Comfort
When you’re out on the water, comfort matters just as much as functionality. Marine air conditioning systems are essential for maintaining a pleasant atmosphere aboard, especially in warm or humid conditions. They ensure that cabins remain cool and comfortable, improving the overall boating experience.
What Are Marine Air Conditioning Systems?
Marine air conditioning systems are specially designed to cool the interiors of boats and yachts. Unlike traditional air conditioners, they use seawater as part of the cooling process. This setup makes them highly efficient and well-suited for the marine environment.
Why Do You Need One?
Spending extended periods on a boat without proper temperature control can be uncomfortable, particularly in tropical or summer climates. Marine air conditioners regulate temperature and humidity, keeping cabins cool and dry. This not only enhances comfort but also protects electronic equipment and interiors from excessive moisture damage.

How to Choose the Right Air Conditioner for Your Boat
When selecting a marine air conditioning system, it’s important to consider the size of your boat. Measuring the interior space of your vessel will help determine the required cooling capacity. Air conditioners are rated in BTUs (British Thermal Units), and choosing the right size unit is essential for ensuring efficient cooling. If the unit is too small, it will struggle to cool the space adequately, leading to increased wear and higher energy consumption. Conversely, a unit that is too large may cool the area too quickly without properly dehumidifying, leaving the air feeling damp and uncomfortable.
Next, it’s crucial to check your vessel’s power system. Marine air conditioners require a stable power supply, and it’s important to ensure that your boat’s electrical system can handle the air conditioner’s needs. Some units may require 115V or 230V, and compatibility with your boat’s voltage is essential for both performance and safety. It’s also a good idea to assess the overall power load on your boat to avoid overloading the electrical system, especially if you’re running multiple systems at once.
Another consideration when choosing a marine AC system is the available space for installation. Some air conditioning units are designed to fit into tight spaces, while others require more room. Before making a purchase, assess your boat’s layout to ensure there is enough space for the air conditioning unit and its components, such as the condenser and evaporator. Some systems are more compact and can fit into smaller boats with limited room, while larger yachts may have more flexibility for installation.
Finally, consider the climate in which you will be using your boat. If you frequently sail in warmer climates or tropical regions, you may need a higher-capacity unit to ensure effective cooling. Units with higher BTU ratings are better equipped to handle the heat and humidity of these environments, keeping the interior comfortable even in extreme temperatures. Conversely, if you’re boating in cooler climates, you may be able to opt for a lower-capacity system that provides just enough cooling without overworking the unit.
Installation Tips for Marine Air Conditioning Systems
Proper installation is crucial for the performance and longevity of your marine AC system. While smaller units can be installed by experienced boat owners, larger systems may require professional assistance. Here are some general tips:
When installing a marine air conditioning unit, it’s crucial to ensure proper ventilation around the unit for optimal airflow. This helps maintain the system’s efficiency and prevent overheating. Additionally, using marine-grade hoses and clamps ensures the durability and longevity of the system, as they are built to withstand the harsh marine environment. For consistent operation, the seawater pump should be installed below the waterline. This positioning ensures that the pump draws in a steady flow of seawater, which is essential for cooling and heat exchange. Proper installation and attention to these details will contribute to the system’s effectiveness and lifespan.
Maintenance for Long-Lasting Performance
To maintain your marine air conditioning system’s efficiency, it’s important to follow some key maintenance practices:
Clean the Filters
Dirty filters can significantly reduce your system’s efficiency by blocking airflow. It’s essential to clean or replace the filters regularly to ensure proper air circulation and optimal cooling performance.
Check the Seawater Pump
The seawater pump plays a crucial role in the cooling process. Over time, it can become clogged with debris or experience wear and tear. Regularly checking the pump for blockages or signs of malfunction ensures smooth operation and avoids system failure.
Inspect the Connections
Leaks or loose connections in the air conditioning system can lead to reduced efficiency or even system damage. It’s important to inspect all hoses and electrical connections frequently to catch any issues before they escalate.
Seasonal Servicing
Before the peak boating season begins, it’s a good idea to have your marine air conditioning system professionally inspected. A thorough servicing can catch any hidden problems, such as wear and tear on components or refrigerant levels, ensuring your system runs smoothly when you need it most.
The Importance of Keeping Cool on the Water
Boating is meant to be a relaxing and enjoyable activity, and a reliable air conditioning system enhances the experience. Whether you’re taking a quick weekend trip or embarking on a longer journey, a well-maintained air conditioner ensures comfort for everyone aboard.
