A micro combined heat and power (mCHP) unit 10 comprises an internal combustion (ic) engine 12 driving an electric generator (14, figure 4). An internal fluid circuit 22 for central heating fluid conveys the fluid so that it extracts heat from a series of components in order of increasing expected normal operating temperature. The coolest component may be the generator (14, figure 4), and the series may comprise the engine crank case (oil sump) 36, cylinder block, cylinder head and exhaust heat exchanger 28, with the exhaust manifold being the hottest component. |
