Buying Guide
- Tank capacity and flow: Choose a 2/3-gallon tank for compact spaces; larger campers may opt for 2.5-gallon units. Consider how many cups of hot water you typically need per hour.

- Installation and footprint: Under-sink units with standard power cords simplify DIY setup. Check dimensions to ensure fit beneath cabinets or inside RV compartments.
- Faucet compatibility and design: Consider 360-degree swivels, pull-forward handles, and finish options (stainless, satin nickel, chrome) to match kitchen aesthetics and backsplash clearance.
- Filtration options: Integrated filters improve beverage taste and reduce particulates; verify filter replacement costs and schedules.
- Durability and warranty: Stainless steel tanks resist corrosion and offer longer lifespans. Confirm warranty terms for residential and RV use.
- Maintenance considerations: Check for easy-tobrowse maintenance steps, dry-start protection, and filter access if applicable.
- RV-specific needs: For campers, anode rods protect the tank from corrosion. Select correct rod size and material based on your vehicle’s water conditions.
