A study of methods and costs for converting buildings' heating systems to a hot water supply in St. Paul, Minnesota is summarized. The general characteristics of an economic analysis are presented for a typical building with a current energy source of either steam district heat or natural gas. Building heating systems were classified by the distribution media - steam, hot water, and air - and also by the heating system configuration - perimeter heating and/or air ventilation heating. Conversion cost results for hot water distribution system buildings average $40/kW(t) of demand, as opposed to $200/kW(t) for the steam perimeter heating systems. The economic analysis results were characterized by the payback period. Payback periods are found to be longer for current steam users than for natural gas customers. (LEW)
