Unsatisfactory operation of an electric snow melter in the Deep Freeze 64 NCEL camp led to the development of a hot-water snow-melting system using excess capacity in the camp water heater as the heat source. In tests of the semiautomatic hot-water melter, water was produced at a rate of 100 gph. This compared to 60 gph with the electric immersion heater snow melter which had been designed to operate on excess generator capacity available during periods of nonpeak electrical load. The hot-water snow melter was used throughout the Deep Freeze 65 summer season to produce about 250 gpd. It was a fast and efficient melter, and had the advantage of employing standard parts whichwere easily assembled and operated. It was concluded that the hot-water melter should be considered for use in camps obtaining water by melting surface snow. (Author)
