Here's an original Lister CS 8/1 start-o-matic. The alternator is complete and is used for both generating electricity and starting the engine.

This CHP is housed in a purpose-build brick outhouse. All the plumbing is neatly installed, but the fue system needs a little more work doing.

The large tube seen here that goes between the engine and the wall-mounted Exhaust Gas Heat Exchanger is a silencer.

The silecer not only reduces exhaust noice, but also changes the exhaust flow from high speed pulses to a smoother more continuous flow. This makes the EGHE more efficient as there is better heat transfer with a smooth continuous flow.

Here's a better view of the EGHE.

This CHP system comprises two water circuits and therefore you will see two central heating water pumps.

The blue water pump circulates water through the engine, through the EGHE and through a Flat Plate Heat Exchanger, which transfers the heat to the second water circuit, which is the house central heating system and domestic hot water.

Both waer circuits are open type, and therefore require a header tank. Shown here is the header tank for the primary (engine and EGHE) water circuit.

 

The primary water pump (blue) takes cool water from the FPHE and pumps it into the EGHE. The water then flow to the inlet of the engine cylinder block. Hot water then flows fromthe engine cylinder head on to the FPHE where the heat is dumped into the secondary system.
