Micro CHP (micro Combined Heat & Power) is the simultaneous production of heat and electricity in individual homes.  Effectively the micro CHP unit replaces the gas central heating boiler and provides heat and hot water as usual, but additionally provides the majority of the home's electricity needs.  Although individual units produce relatively small amounts of electricity, the significance of micro CHP lies in the vast number of systems which may ultimately be installed in the millions of homes in the UK and other European countries where natural gas is currently the dominant heating fuel. 

It is anticipated that, ultimately, micro CHP may provide 20% or so of the UK's electricity generating capacity; unlike a number of other microgeneration technologies such as solar PV or baseload nuclear, this generation occurs during periods of peak electricity demand, thus providing high value to the energy system.

This site is provided as an information source for the general public and students interested in micro CHP.  Links are provided to manufacturers' sites, but please note that we do not endorse or sell any products.



A simple introduction to what micro CHP is and how it works.

In 2004, the first micro CHP units became available in the UK.  Today, products based on both engine and fuel cell technologies are available in Germany, UK, Netherlands, Japan and USA.

Micro and mini CHP products which are available now as well as some of those under development.

Information on so-called "enabling technologies" which enhance the performance and value of the micro CHP products themselves is also included.

As interest in micro CHP grows, numerous conferences and similar events are continuously taking place.

The list is not exhaustive; please send details of any events you think should be included.

This section includes links to international energy related sites, with particular focus on Distributed Generation and micro CHP. 

Links to manufacturers and developers of micro CHP can now be found within the relevant product sections.


Micro CHP can provide significant economic, social & environmental benefits.  However, before investing in micro CHP, you can make a simple economic payback calculation using this excel spreadsheet.  Download and insert the relevant data for your home.

At last the definitive text on micro CHP.  You can preview the contents here and order on line.

Other books shown on this page include papers by other authors and may be ordered from the publishers.

An archive of papers relating to micro CHP.  Although papers will be added on an ongoing basis, please note that individual papers will not be changed, so check the publication date to see how relevant they are...and to see how wrong my predictions were!

You may also be interested in other types of microgeneration.  This links to a partner site containing basic information on other microgeneration technologies as well as links to additional information sources.
