Rheem HotWave Multipurpose Heated Hose Nozzle Sprayer - Outdoor Heated

Our review of the Rheem HotWave finds it most useful for homeowners, RVers, and pet owners who need on-demand heated water outdoors without complex installation. The single biggest reason to buy is the convenience of a handheld heated nozzle that connects to a standard garden hose and a 120V outlet, delivering warm water for washing pets, rinsing patio furniture, or camping chores. It is straightforward to use and offers temperature and pressure control in one compact tool.

Key Features

• On-demand heated water: Provides warm water immediately at the nozzle so you do not need a separate outdoor heater or tank for rinsing and washing tasks.
• Standard hose and outlet connection: Attaches to a regular garden hose and plugs into a 120V, 15 AMP outlet with a 25' electrical cord and built-in GFCI for safer outdoor use.
• Four adjustable spray patterns: Flat, Jet, Center, and Shower settings let you choose the right spray for pet grooming, rinsing dishes, or cleaning outdoor surfaces.
• Water pressure control: A single-finger control lever gives fine control over flow so delicate jobs can be done without high pressure.
• Trigger lock and hook attachment: Lock the trigger for continuous flow and hang the unit to use as an outdoor shower during camping or RV use.

Who It's For

The Rheem HotWave is ideal for pet owners who want warm water for bathing animals outdoors, RV and camping enthusiasts who need a portable heated rinse or shower, and homeowners who rinse patio furniture, grills, or gardening tools without lugging water indoors. Its simplicity and direct hose-to-plug design make it attractive for users who want quick heated water without plumbing changes.

Those who need very high water temperature or professional high-pressure cleaning should look elsewhere; HotWave prioritizes convenience and gentle heated flow rather than replacing a dedicated indoor water heater or a commercial pressure washer.
