Does micro CHP for a new build make sense?

    Looking at the potential for gas powered micro CHP for a new build instead of a high efficiency gas boiler. Plan would be to feed a large buffer tank which would also have solar panels connected. Doing some research came across some UK specific information http://www.greenconsumerguide.com/powergenminisite/whispergenunit.htm

    Does anyone have any experience of installing micro CHP on a domestic scale in this country or know how the economics of one of these units stacks up

    PS - have no connection with the company link above, just somewhere I found info

    will you have a swimming pool or some other demand for DHW if so yes it could be ok. if not you would have a lot of extra hot water in the summer without including your solar. turning it off means you only get to use 50% of the time. So i would say no, but if you really want to look into get a professional to size it for you taking account of the two different heating patterns. it is a very price sensitive technology. you will still need to import electricity even in the winter if sized right i would say.
