Standby Generator Starting in cold weather
Scenario 1: Emergency diesel generator in a non-insulated outdoor enclosure. In winter, the 1500W coffee maker (also known as a water jacket heater) is brewing continuously since the thermostat is set to ~27C/ 82F. Big waste of energy and a high cost for this parasitic power.
Scenario 2: Air cooled Lister generator set is available as surplus. Love to buy it, but they were originally mounted indoors where the room temperature kept them warm. I don't have such a room in my house. If mounted outdoors, what options exist to keep it warm and ready to start when required?
Scenario 3: Natural Gas (vapor) engine. Does this engine need to be kept warm like the diesel? I'm thinking the coffee maker temperature can be severly reduced to say 0C/32F or even lower?
So the overall question is how to reduce the parasitic operating cost of a standby generator in cold weather while it is waiting for a power failure?
