Performance of WhisperGen micro CHP in UK homes
Response to the first Carbon Trust
interim report 2006
This report discusses the performance
of the WhisperGen micro CHP based on data from the Carbon Trust
micro CHP Field Trial and complementary test work.
Summary conclusions are:
•
In all homes significant Carbon savings were
demonstrated
•
Average CO2 savings for the sample homes
were 16% and up to 19%
•
Family homes, typical of target market,
save 1.1-1.5 tonnes of CO2 annually
•
The value of electricity generated can pay for the
marginal investment in as little as 3 years in the typical family
home
Since publication of
this report additional data has been acquired and an updated report
is available on the Carbon Trust web site. It contains a great
deal of valuable information and confirms the target market for
Stirling engine based micro CHP as being for larger family homes
and, in particular, those for which it is difficult to implement
traditional energy efficiency measures such as cavity wall
insulation. This represents about half of the homes in the UK.
Since that time, the
WhisperGen unit has undergone significant development and
improvements in performance, so that the savings for current
products are expected to be be somewhat better. At the same
time, other micro CHP products are becoming available so that the Carbon Trust
report represents a very conservative view of the potential benefits
of this technology.
