In recent years, heat pumps have emerged as a promising new form of technology with a relatively low environmental impact. Moreover, they have presented householders with an opportunity to reduce their heating bills. Heat pumps can heat a building by 'pumping' heat from either the ground or the air outside: an intriguing process which utilizes principles that are somewhat analogous to those employed in the domestic refrigerator. Armed with the practical information contained in these pages, homeowners will have the necessary knowledge to take advantage of this potentially low-carbon technology to heat their properties. Now in an updated new edition, Heat Pumps for the Home describes what a heat pump is, how it works, the different methods of pumping heat and the importance of an appropriate and well-planned installation. It also provides you with the information that you need in order to make up your own mind about whether a heat pump might be appropriate to your own circumstances, and also demonstrates what you need to do to in order to make the system work efficiently.

This comprehensive book presents a thorough analysis of the wind turbine technology that is suitable for use on a small scale and presents an overview of the process of installation. Covering both small-scale on- and off-grid installations, Small-Scale Wind Power Generation is essential reading for all those wanting to use wind power to produce clean energy: it will help them to understand the nature of the wind in their area, to appraise potential sites and to assess the likely capacity of any wind power turbines that are installed. The authors also discuss the computer software that is suitable for predicting the likely financial benefits and provide valuable information about how to assess the economic viability of wind installation and how to calculate the resultant carbon savings.
