We designed the Geyser System to be safe and easy enough for a child to use, with 2 layers of safety at every point of contact.
Chiefly, you want a hot shower, but not too hot. For that reason, the Geyser features two thermostats to monitor the water temerature. If the water is above 113°F / 45°C, the pump will automatically disable itself until the temperature returns to 85-95°F / 30-35°C. This is to prevent you from adding hot water, forgetting to add cold water, and scalding yourself or your loved ones. If you are using the Geyser in conjunction with your camp stove, we strongly advise adding cold water first, then topping off the Geyser with hot/boiling water.
Using the built in water heater? Once the water reaches 95°-107° F / 37-43°C , the heater will shut itself off.
In addition to letting you know when to wrap up your shower, the built in water level sensor will never let you run the built in heater without water in the unit.
Additionally, the lid switch at the top of the unit makes sure you won’t . The built in water heater will only turn on when the lid is screwed on securely.
