Description

Dual-Purpose: Cabin & Outdoor Shower

Standard RV heaters are hidden away. The GWH-4 adds utility where it counts.

  • Front-Facing Outlet: A specialized port on the exterior door allows instant connection of a shower hose.

  • Outdoor Utility: Perfect for “Van Life” scenarios—washing muddy dogs, cleaning sandy feet, or rinsing surfboards outside the vehicle without tracking dirt inside.

  • Internal Supply: Simultaneously supplies steady hot water to the RV’s internal kitchen and bathroom faucets.

Instant Heat, High Efficiency

Built for the demands of full-time road travel.

  • TP2 Pure Copper Exchanger: Utilizes high-purity copper for maximum thermal conductivity and corrosion resistance against varied water qualities.

  • Segmented Combustion: The smart burner automatically adjusts the flame stages based on incoming water temp and flow, saving propane while delivering a massive 65,000 BTU load.

  • Zero Wait Time: Tankless design means you never run out of hot water, no matter how long the shower.

  • User-Friendly: Simple touch interface replaces vague analog knobs found on older RV heaters.

The Perfect Retrofit Solution

Engineered to replace outdated 6-gallon tank heaters.

  • Standard Cut-Out: Fits openings between 12.6″ x 12.6″ (Min) and 13.1″ x 13.1″ (Max), the industry standard for US travel trailers and motorhomes.
