Ideal for use with deck showers on smaller boats—and great for warming wetsuits!This water heater connects to a 12V power supply, meaning there is no need for a generator, inverter or shore power. The compact design fits in small spaces and because it operates on 12V DC installation is no longer tied to the engine room—so you can fit it in the galley, transom or other storage areas. It heats water in less than an hour and retains heat up to 10 hours!Key Features3-gallon capacity12V operation (electric only, no heat exchanger)Ideal for deck showers and warming wet suitsIntegrated temperature and pressure valveThermal cut-out and heat indication outputIntegrated anode for longer lifeRelay allows for switching at the helm for ease of use and control
