Key Specs for Choosing Your Unit
-
Check the fuel source
Your existing gas line determines which heater fits. The top pick uses natural gas, which is often cheaper and piped directly to homes. The second option runs on propane, requiring a tank. Choose natural gas if you have a permanent line. Select propane if you need portability or lack gas infrastructure. Both models share the same 20L size, so the fuel type is your primary decision point for installation compatibility.
-
Verify flow rate needs
Flow rate dictates how many fixtures run at once. The top two models deliver 5.26 gallons per minute. This supports whole-house outdoor use, allowing showers and sinks to operate simultaneously. The third model offers 4.76 GPM. This lower rate suits RVs or single-outdoor showers. If you need high volume for multiple taps, stick with the 5.26 GPM units. Lower flow rates may struggle if multiple outlets open at once.
-
Confirm outdoor placement
All listed units are built for outdoor installation. They feature weather-resistant white exteriors. This allows mounting on patios, decks, or exterior walls without weather damage. Ensure your site has proper drainage and ventilation. The compact dimensions, roughly 14.4 inches wide, fit tight spaces. Verify your local codes allow outdoor gas appliances. Proper placement ensures safety and longevity for the digital components inside.
-
Assess remote control value
Remote panels allow temperature adjustment without approaching the unit. The top natural gas model includes a remote panel for precise heat control. The propane option also features remote convenience. The RV model adds remote control for easy setup. This feature is useful for hard-to-reach outdoor locations. It lets you adjust settings from a distance. If your unit is mounted high or in a tight corner, a remote simplifies daily operation significantly.
-
Match voltage requirements
Electrical needs vary by model. The RV-specific heater requires 120V power. This ensures the electronics and display function correctly. The other models do not list specific voltage in their attributes, implying standard connections. Check your power source before buying. Ensure you have the correct outlet nearby. Proper voltage prevents damage to the digital display. Always verify electrical specs match your home or RV supply before installation.
