here are my electric and gas bills to try and give info on what i use and how much it costs.
little background on the house.
built in 1934, 2 story plus basement(no insulation), each floor is 20'x22'x8'. 10'x11' and 6'x8' rooms with crawl spaces under them open to basement( no sealing and no insulation)
2x4 walls with foam insulation installed. (probably not filled the greatest) 1/2" foam board(pink) under vinyl siding (seams untapped)
attic has 2 rows of 9" batt insulation rolled out in a crisscross.
newer double pane windows.
still has a lot of work in the sealing and insulating areas.
planning on sealing and insulating the bond-board in the basement and crawl space this fall.
