More adventures in my new home in the Poconos!

so our first electric bill came in at $260, and we were shocked! we changed our high use lights to LED bulbs and changed our thermostat from 68 to 63 degrees in the occupied rooms. The next bill came in and it was $420!! thats almost as much as my mortgage!

I wear we couldn't be using that much electricity so today I went breaker by breaker to determine what was using so much. sure enough it is our electric baseboard heaters. In our unscientific test it brings the rotation of the analog electric meter from 20 mississippi's to 3 mississipi's.

Could something be wrong with the wiring? or is this just how much it costs for electric heat?

About the home: 2600sq ft, individual room thermostats and a propane fireplace in the kitchen. Thermostats are set to 63 where we stay, night time and bathrooms set to 50. I'm not sure if i need to keep heat on in the bathrooms to prevent pipes from freezing,

Thank you guys!
