My house isn't very big, and I live alone (so less demand for hot water

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.

Okay - if you live in a pretty cold climate, that may be it.

Sounds like you need to do some demand-side management :-).
