Waiting for the Police to Show Up

We have had a 1500 watt electric heater running in the bathroom for the last couple of weeks. We had to start using it as the drywall mud, and then the tile mortar, were not drying in the 14 degree bathroom.Today we started using the second heater as it was just too chilly in here. I guess you can't get past the fact that it is late October in Winnipeg. We are wondering how big the spike in your electrical usage has to be, and how long it has to last, before Manitoba Hydro alerts the police about a possible grow-op.
Of note: I'm impressed at the shutter speed of this camera-the blades of the fan look to be still.
I am equally appalled by how much dust is evident in this picture.
