Book Review: Why Heat Pumps Fail by Craig Moreton

A paperback copy of Why Heat Pumps Fail by Craig Moreton lying on a desk in front of a keyboard. The cover shows a commercial heat pump split by a red crack, with the subtitle "The Engineering Mistakes That Kill Performance – And How to Avoid Them".

For designers and specifiers of heat pump installations, Why Heat Pumps Fail is an invaluable practical guide. Craig Moreton examines every stage of a successful project, from system design and specification to installation and commissioning, with the level of detail needed to understand not only what good practice looks like, but why it matters.

One of the book’s key strengths is its focus on the installation as a complete system. Moreton makes clear that the heat pump itself is often the most dependable component: when supplied with the right conditions, it produces hot water as intended. Performance problems usually arise from the way the wider system has been designed, installed, configured or commissioned. Although many installers recognise the factors that can reduce efficiency, this book explains the reasoning behind them and shows how real-world conditions can turn a promising installation into one that fails to meet the customer’s expectations.

The book is particularly well suited to business owners and directors of heat pump or air-conditioning companies, as well as design, installation and commissioning managers. It offers a useful framework for checking that all the essential conditions for a successful installation are in place. The depth of the detail reflects Moreton’s extensive knowledge of heat pump design and commissioning process, which he shares in a practical and distinctive way.

Even experienced industry professionals will find value in using the book to test and confirm their existing knowledge. Comprehensive, technically informed and highly relevant to professional practice, Why Heat Pumps Fail is a highly recommended read for engineers, specifiers and anyone responsible for delivering reliable heat pump installations.
