They used (if I remember correctly) a Fiat 127 engine... it drove a generator and provided hot water for heating and domestic use... It was all super-insulated and the engine was able to run at its most efficient speed... I think it was connected to a number of houses in a small community.
I guess the key would be matching output to requirements... in Cyprus there would be little point having a system that produced hundreds of gallons of hot water in the summer for instance...
Not quite correct about the need for hot water, restaurants, bakeries, hotels, and certainly some industries require a lot more hot water than they can produce with the normal solar water heaters. They could very easily benefit from micro-CHP.
The thing would be to use the hot water for cooling, possibly with some sort of heat pump? I have no idea if that is viable.
