Central Heating: A Design and Installation Manual is a guide to modern domestic heating systems for those involved in the trade. The book discusses the benefits of heating systems, the effects of heating, the effect of insulation on comfort and cost, and the process of heat and moisture transfer. The text also describes the concepts, possibilities, and prevention of condensation; the basic heating system; and circuit hydraulics and variation. The chemical effect of water, the selection of hardware (i.e. gas-, oil-, and solid-fuel boilers; emitters; and cylinders), temperature control, and the design of a heating system are also considered. The book tackles the relationship between boiler size, system size, capital cost and running costs, as well as the installation of heating systems. The text will be invaluable to students taking up central heating installation related courses, householders considering installing central heating, and electricians.
