I'm considering getting a home standby generator. I have an existing small propane tank that's only used for a gas fireplace which is rarely on. I'm trying to figure out if I need a bigger tank.
My home has a peak power usage of about 16kw, but that's way, way more than my typical usage. I generally am not pulling more than 2kw in the winter, and perhaps 5kw in the summer. Averages are closer 1kw.
I can figure out the fuel usage based on these loads, but I do not know if a generator has significantly variable fuel consumption depending on the power consumption of the house. In other words, if my house is pulling 10kw, is that using twice the fuel as when it's pulling 5kw? Or is it more chunky?
