Lister CS
Lister CS
This page is about using a Lister CS single cylinder diesel stationary engine for a Combined Heat and Power system running on waste vegetable oil.
We have purchased one (yet to be collected).
It is a Lister CS 8/1, that's one of the later models producing 8HP at 850rpm rather than the normal 5 or 6 hp at 600rpm

Apparently typical consumption is between .25 and .33 litres per hour for each kw of load so assuming 4kva generator running at 75% load that would be about 1 litre of fuel per hour.

Imagine a power plant that produces electricity and heats your home and water... imagine this power plant that sounds quiet and soothing, not loud and noisy like other power plants. Also imagine a power plant that instead of belching nasty diesel exhaust fills the air with an aroma of delicious french fries. Imagine this power plant doesn't wear out and burn up after a couple months of use, but instead can run up to 40 years without being overhauled and when it finally does need working on, it is simple and easy to repair.
The Lister CS (cold start) diesel engine was first produced in 1929. With a running speed of 600 - 650 RPM, and a simple engine design the Lister CS diesel engine is now legendary for its record of longevity with many engines running in rural areas for 40 years or more. With its slow speed is quiet and gentle sounding. Indirect injection and its slow cycle speed aid the listers ability to burn alternative fuel such as waste vegetable fuel oil (wvo).
Some stats on the 6hp version
Weight 330kg (engine only, not including generator or mounting base) Mechanical Power Output 4.47kW (6 hp) Heat Output 6kW maximum (not including heat recoverable from exhust system) that's about 330 litres of hot water per hour at 60 degrees C Fuel Consumption 3 litres every 2 hours when running a 2.5kW electric load
Basically, it's an engine that can be used as a combined heat and power plant running on the waste vegetable oil will collect from local restaurants. We agreed a few weeks ago that we'd invest in one of these systems as it would make our squat autonomous from the power companies, providing not only electric but also heat and hot water. We'd run it for about 4 hours each day during peak electric needs (electric oven anyone?) and recharge the battery bank during this time. At the same time we'd heat a tank of water to provide hot showers and water to wash up with.
