The author is an independent engineer who is familiar with most heat pumps, with allegiance to none.The book is mostly aimed at the consumer, and lays out the options and issues starting from the basic first principles. It has a refreshingly straightforward approach, with enough technical detail to satisfy architects and installers too. It is completely jargon and hype-free, and tackles all types of system. It discusses different building types and their suitability for this technology in an un-biased and neutral way.
Discusses wider environmental issues too.

Domestic RHI is here!

See DECC website

In spring 2014 the Government's Renewable Heat Initiative (RHI) will pay Domestic consumers for renewable heat:

Air source: 7.3p per kWh
Ground source: 18.8p/kWh
Solar Tharmal: 19.2p per kWh
Biomass Boiler: 12.2p per kWh

What is a Heat Pump?

More and more homes in the UK are being heated by heat pumps. This little understood concept has been around for many years, but has only recently become of interest due to the current concerns over global warming and environmental issues

This technology is not appropriate for every situation, and there are pitfalls to avoid. It is mostly viable in remote areas where mains gas is not available. It is particularly suited to well insulated houses with underfloor heating, or background heating for older houses.
