Chronic underheating is commonplace among poor households in cold-climate regions of developing countries beyond the reach of district heating and gas-distribution networks. Until fuel switching is possible, high-efficiency, low-emissions (HELE) technologies offer a cost effective, intermediate solution to meet the heating aspirations of underserved populations.
Recent pilot experience in Kyrgyzstan shows that switching to HELE heating stoves yields substantial benefits, including dramatically reduced emissions, better health, and savings in household fuel expenditure.
