Why Choose InstaShower 6, 42,000 BTU RV Tankless Water Heater

Choosing the right InstaShower 6, 42,000 BTU RV Tankless Water Heater is essential to ensure that it meets your specific needs and provides optimal performance. Here are some factors to consider when making your selection:

BTU Rating: 

The BTU (British Thermal Units) rating indicates the heating capacity of the water heater. Consider the size of your RV and your hot water usage requirements to determine the appropriate BTU rating. The InstaShower 6 offers a BTU rating of 42,000, which is suitable for smaller RVs or moderate hot water demands.

Flow Rate: 

The flow rate refers to the amount of hot water the water heater can deliver per minute. Assess your hot water needs, such as the number of faucets, showers, or appliances that may be running simultaneously, to ensure that the InstaShower 6 can meet your desired flow rate.

Space and Installation: 

Consider the available space in your RV for installing the water heater. The InstaShower 6 is designed to be compact and space-saving, making it suitable for RV installations with limited space.

Fuel Source: 

Determine the fuel source that best suits your RV setup. The InstaShower 6 is available in both propane and natural gas models, allowing you to choose the option that aligns with your RV's fuel system.

Energy Efficiency: 

Look for energy-efficient features in the water heater, such as a high Energy Factor (EF) rating. This indicates how efficiently the unit converts fuel or energy into hot water. A higher EF rating means better energy efficiency and potentially lower operating costs.

Safety Features: 

Ensure that the InstaShower 6 has appropriate safety features, such as flame failure detection, overheating protection, and pressure relief valve. These features help maintain safe operation and protect your RV from potential hazards.

Warranty and Customer Support: 

Check the warranty offered by the manufacturer and the availability of customer support. A reliable warranty and responsive customer support can provide peace of mind and assistance if you encounter any issues with the water heater.

While the InstaShower 6, 42,000 BTU RV Tankless Water Heater is designed to provide reliable hot water in your RV, there are a few common problems that you may encounter. Here are some of the issues that users have reported:

Fluctuating Water Temperature:

Ignition Failure: 

If the water heater fails to ignite, it may be due to issues with the fuel supply, gas pressure, or the ignition system. Check the gas supply, ensure proper gas pressure, and inspect the ignition components for any damage or malfunction.

Scale Build-up: 

Over time, mineral deposits and scale can accumulate inside the water heater, affecting its performance and efficiency. Regular descaling and maintenance are important to prevent scale build-up. Refer to the manufacturer's guidelines on how to descale the unit properly.

Leaks: 

Water leaks can occur in the water heater connections, fittings, or valves. Inspect the unit for any signs of leaks and tighten any loose connections. If the leaks persist, it's advisable to contact customer support or a qualified technician for further assistance.

Error Codes: 

The InstaShower 6 may have built-in error codes that indicate specific issues. If you encounter an error code on the unit's display, consult the user manual or contact customer support for guidance on troubleshooting and resolving the issue.
