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.

Precise Temperature Management

Complete control from the comfort of the driver’s seat or living area.

  • Digital Remote: Comes with a wired wall-mount controller that displays real-time temperature, flame status, and fan operation.

  • Wide Range: Users can dial in their perfect temperature between 95°F and 124°F (35°C-51°C).

  • 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Engineered to replace outdated 6-gallon tank heaters.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.

  • Easy Access: The door design provides quick access to internal components for maintenance without removing the entire unit.

Certified Safety for Peace of Mind

Safety is non-negotiable in mobile living spaces.

  • CSA Certified: Meets rigorous North American safety standards for gas appliances.

  • Anti-Freeze Protection: Active ceramic heating elements prevent the heat exchanger from cracking in cold weather.

  • Comprehensive Sensors: Includes Air Pressure Switch, Flameout Protection, Overheating (>85°C) Cut-off, and Water Overpressure Relief Valve.
