This video shows the utilities usage for a full year encompassing part of 2016 and 2017. The heat pump uses electricity through either driving the pump or, when on emergency heat, using an electric grid. The electric bill is a reflection of this usage. Of course there’s the lights, dishwasher and fridge but you’ll get an idea of each month’s usage, relative to the one before or after it.
We used the Masonry Heater, featured in the “Highlights” section of this website, and that curbed some of the potential electric usage through allowing the heat pump and electric grid to not be used as often. The utility usage is also a reflection of the Masonry Heater at work.
With the Strawbale Insulation giving 18 inch thick exterior walls, the double pane windows and the Masonry Heater, the house will hold about a 30 degree difference for extended periods of time where the heat can stay off.
