The Calientamigos system allows impoverished families living without hot running water to heat and pressurize water for bathing, cooking and cleaning. The system comprises three modular components: BOMBA, a safe, portable electric water heater (like an inside-out electric tea kettle) that safely heats 5 gallons of water to 110 degrees Fahrenheit in 15 minutes - enough for showers for 2 adults or 3 children; CORAZON, a simple to use foot pump that pressurizes the warm water; and GOTA, a multi-purpose faucet head. Calientamigos is flexible enough to work with any container found around the home. It heats water more quickly, at a lower cost than existing methods, is more affordable than existing market options, and more accessible than installing a gravity-fed water system. Calientamigos helps kids stay clean and healthy for school, and frees their families from the time and energy spent inefficiently heating water.
