Books by Fred B Orr

Originally published in 1915, this book holds much relevance today as district heating is again being considered in many areas. Topics covered include origin and development of district heating, selling of heat, heat distribution systems, metering, district-heating stations, methods of estimating heating requirements in buildings, estimating miscellaneous steam requirements in buildings, relation between heat load and electric load in buildings, the use of heating data in making estimates on the comparative costs of isolated plant and central-station service, and the relation between central-station heating and central-station lighting and power. "The object of the book is not only to impart a general knowledge of District Heating to those who wish to study the subject, but also to promote the interests of District Heating companies. For this purpose various points on economical operation are suggested, as illustrated in the methods practiced by companies which have made a success in this line of work." - The Authors
