  1. Peruvian Water Heater By Kevin Stubbs and Brad Ivey

  2. Introduction • The purpose of this project is to develop a stove water heater capable of efficiently heating water using excess cooking heat for the villagers in rural living conditions. • Villagers obtain their water from mountain springs with water temperatures of about 50 °F (10 °C). • A warm water source will greatly improve the frequency of bathing and quality of health for the villagers.

  3. How it Works • The tank sits above the stove • Cold water flows down through the fire and is heated • The hot water rises and the water begins to flow. Question: How much pipe do we need in the oven to heat the water to 130° F? Tank Water Flow Oven

  4. Assumptions • The pipe that runs from the stove to the tank is perfectly insulated. • qs is constant within the stove • Constant mass flow rate

  5. Calculations

  6. Conclusions • 2.57 feet of pipe is required inside the oven to meet the desired temperature • qs = 1001.72 W is required from the fire • This is very possible to construct and will benefit the Peruvians of Salkantay
