Frequently Asked Questions
Can portable water heaters work at high altitude?
Yes, but performance may be affected. Propane burns less efficiently at altitudes above 8,000 feet, reducing heat output by 10-15%. I've successfully used portable water heaters for camping at over 10,000 feet in Colorado, but had to adjust my expectations and allow extra heating time. Some manufacturers offer high-altitude adjustment kits for optimal performance.
How much propane does a camping water heater use?
Consumption varies by model and usage patterns. A typical 34,000 BTU unit uses approximately 0.8 gallons of propane per hour of continuous operation. In real-world camping scenarios, expect 4-6 showers from a standard 20-pound propane tank. Factors affecting consumption include input water temperature, desired output temperature, and flow rate settings. For extended trips, consider propane water heater for RV setups with larger tanks.
Are portable water heaters safe for indoor use?
Most portable propane water heaters are designed for outdoor use only due to carbon monoxide production. However, some models are certified for indoor use with proper ventilation. Electric models are generally safe indoors. Always check manufacturer specifications and local codes. When camping in RVs, ensure adequate ventilation and consider installing CO detectors. For indoor applications, explore electric water heater for RV options that don't produce combustion gases.
What water pressure is required for optimal performance?
Most portable water heaters require 20-80 PSI for proper operation. Too low pressure prevents ignition, while excessive pressure can damage internal components. I recommend installing a pressure gauge and regulator system for consistent performance. City water typically provides 40-60 PSI, perfect for most units. Well water systems may need pressure tank adjustments, while gravity-fed systems often require booster pumps.
How do I winterize my portable water heater?
Proper winterization prevents freeze damage and extends equipment life. Start by completely draining all water from the system, including internal components. Run compressed air through water lines to remove residual moisture. Add RV antifreeze to any water pathways that can't be fully drained. Remove and store batteries in a warm location. Cover the unit and store in a dry, protected area. Consider professional winterization for valuable units, especially when dealing with RV water heater replacement scenarios.
Can I use a portable water heater with well water?
Yes, but water quality significantly impacts performance and longevity. Well water often contains minerals that cause scaling and sediment that clogs components. Install a quality pre-filter system and consider water softening for hard water areas. Regular descaling becomes critical with mineral-rich water sources. I've found that units perform best with water that's been filtered and treated. For permanent installations, consider upgrading to models specifically designed for challenging water conditions.
What's the difference between tankless and tank-style portable heaters?
Tankless units heat water on-demand as it flows through, providing unlimited hot water but requiring adequate flow rate to trigger operation. Tank-style units store heated water, providing instant hot water availability but limited capacity. For camping applications, tankless models offer better portability and unlimited capacity, making them ideal for extended stays. Tank models work better for quick, high-volume needs but require recovery time between uses. Consider your camping style and group size when choosing between these options.
