In this months IEE review there is an interesting article on small scale
CHP for domestic installation in the UK.


Is this review on-line?

Hope its of interest.

Thanks. Told me nothing new. Whispergen has been around quite a time
selling marine applications CHP units. They are only a samll NZ company.
They kust have found a manufactrer to produce the unit in bulk. MicroGen
have been promoting their unit for about a year now.

These are not full CHP units. They are to supplement electricity usage
taking and feeding the grid. There running costs will depend on what the
electricity supplier will buy back power from you. To kick start take up it
must be a 1:1 ratio. The take up of these units is the biggest hurdle. As
the article points out, it is ignorance by installers that will be a large
hurdle. They haven't even accepted condensing boilers yet, thinking they
are complex.

Full CHP which can be installed in a remote off-the-grid house is different
in that most use diesel units running on heating oil. These can be very
expensive to run if not on full load. Running a genny just for lights and a
TV is expensive as a lot of energy is wasted. You need to have a large
thermal store to store the heat that would otherwise be wasted, and it must
be turned off at night with battery LV lights and water pump used.
