More comprehensive pilot testing is required outside a laboratory setting before implementing a similar project at scale. The relationship between fuel efficiency and stove operation is direct and complex. Fuel efficiency gains observed in the laboratory and field testing prior to implementation were achieved under normal operating conditions. The evaluation observed more varied operating procedures among MCA stove owners. The result was observation of little to no fuel savings, warmer temperatures in the home, and/or fuel savings that were less than those achieved in the laboratory (30%). While demonstration and written instructions were provided to consumers, alternate methods or greater investment in the same is recommended. Laboratory level fuel savings are still attainable by stove owners who operate their stoves according to the instructions.
