I'd struggle to see how a 20kW generator struggles to to run a home, unless you've also got heated floors, saunas, steam baths, water and space heaters, electric stoves and ovens all running at the same time :-).
My house isn't very big, and I live alone (so less demand for hot water for example), and I hit a peak demand of 15kW a couple of months ago during a cold snap (I've seen it higher, maybe 16kW IIRC, just didn't dig any deeper). I probably took a hot shower while the heat was running, but I didn't cook anything that day, which could easily pulled another 1-2kW (oven, microwave, etc.). And that's without any water/septic pumps. Electric heat pumps are great for power efficiency until the temperature drops and they switch over to pure electric heat. -- Chris Adams <cma () cmadams net>
