Pros and Cons of Buying Whale Marine Seaward Gallon Water Heater (S700) with Rear Heat Exchanger (Stainless Steel 766478947925)

1. **High Energy Efficiency:** The Whale Marine Seaward water heater features a rear heat exchanger, which allows for the transfer of heat from the engine coolant to the water in the heater. This results in significant energy savings as the engine generates the heat required to keep the water warm, reducing the need for an additional heating element.

2. **Compact Size:** With its rear heat exchanger design, the S700 water heater has a smaller footprint compared to traditional water heaters, making it an excellent choice for vessels with limited space.

3. **Durability:** The stainless steel construction of the S700 water heater ensures a long lifespan, as it is resistant to corrosion and other forms of wear and tear, common in marine environments.

4. **Consistent Water Temperature:** The engine-heated water in the S700 provides a consistent water temperature, which is essential for various applications, such as showering, hand washing, and kitchen use.

5. **Compatibility:** This water heater is suitable for various marine applications, including sailboats, powerboats, and RVs, making it a versatile option for boat owners.

6. **Installation Complexity:** The rear heat exchanger design of the S700 water heater might require more complex installation compared to traditional water heaters. Though the system is relatively straightforward, it may require professional assistance to ensure proper installation and functionality.

7. **Limited Heating Capacity:** The S700 water heater has a smaller heating capacity compared to traditional water heaters. This means it might not be suitable for larger vessels or multiple simultaneous water usage.

8. **Engine Dependency:** The water heater's performance is dependent on the engine's operation. This could be problematic if the engine is not running, as the water heater will not function unless the engine is producing heat.
