2015 Clayton Mobile Home Electric Usage Graph
When deciding to move into our single-wide 2015 Clayton mobile home, we searched and searched for information on what to expect for electric bills in manufactured homes. Unfortunately we found more complaints than praise targeting poor insulation and electric bills well into $300’s. We worried and fretted and directed our research into the construction of the home to get a better idea of what to expect for energy efficiency. We found that mobile homes build before 1976 had no guidelines/requirements for building and insulation. From 1976 onward HUD codes were implemented. Then after 1994 insulation had to match the geography of the home use location. It’s been my understanding that homes were either constructed with 2X4’s or 2X6’s which determined the amount of insulation. From our searching it seemed that most of the complaints of poor energy efficiency was from owners prior to 1976 or those with only 2X4 walls. To our relief newer homes (we specifically were looking at Clayton’s) are build with 2X6’s and therefore packed with 6 inches of fiberglass insulation. To quote our home’s paperwork exactly: “R19 wall insulation is 6.5″ thick as provided by the insulation manufacturer, and is compressed to 5.5″ to fit in homes that have a 2X6 wall cavity. The net R-value is reduced to R-17.8”. If you’re curious our floors are 3.5″ thick, R11, fiberglass, our ceiling is loose-fill fiberglass R25 at a settled depth of 7.08″, and our roof is fiberglass blankets. This is all be information that your manufacturer and/or sales rep should be able to provide you with. In our case our sales rep was more knowledgeable and then we saw all the numbers in that great big stack of final paperwork.
We are happy to report that in our Maryland location we saw no bill into the $300’s range during even the winter months. See the graphs below that begin when we moved in, in August 2015 to the present. On average, in the summer we keep the AC temperature set to mid 70’s and in the winter the heat is set to around 70 degrees (with heat tape plugged in). For our bill costs we’re charged a generation charge+transmission charge+energy cost adjustment. Then we have “reoccurring fees” labeled as: customer distribution charge, distribution charge, electric universal service fee, administrative credit, cogeneration PURPA surcharge, franchise tax, emPower MD surcharge, demand resource surcharge, and MD environmental surcharge. Those fees can be as high as 30-40% of our bill (higher the bill the higher the %). Electric bills after February 2016 are 100% green energy (wind generated from Texas). Our only other home bill is water. Our heat, lights, stove, and hot water are all electric. I’ll update this chart as the months roll by.
