Buying Guide
Key purchase considerations for 120V hybrid water heaters include capacity, fuel flexibility, installation space, and electrical requirements. A hybrid model with dual-fuel capability can reduce propane usage while still offering electric heat at campgrounds. When evaluating capacity, match the tank size to typical hot water usage and available space. For RV setups, ensure the heater fits standard openings and doors to simplify installation.
Electrical compatibility matters: some units require a dedicated breaker (often 30A for higher draw), while others operate within standard 120V circuits. If you select a conversion kit (like Camco or Briidea), confirm compatibility with your existing tank model (Suburban, Atwood, etc.) and verify included hardware meets your installation needs.
Build quality and corrosion protection influence long-term reliability. Look for features such as magnesium anode rods, robust insulation, and leak protection. Temperature control is valuable; models offering adjustable thermostats or preset temperatures provide consistency for household or RV use. Finally, assess warranty coverage and replacement parts availability to minimize downtime and maintenance costs.
