Electric heat is really expensive. My house is all radiator heat/gas except my bedroom, which ran on electric heat before I installed mini splits. I kept it at 55 and my electric bill still skyrocketed in the winter. I can’t imagine with the rate hikes now what folks with electric heat are going to pay.

Enrolling in the Mass Power Choice electric option someone mentions here will help a little. If she’s not already turning it down when she leaves and sleeps, she should start doing that. Electric heat sucks, unfortunately
