Heating Our Home with Wood

This past summer we had our roof re-shingled due to the massive hail storm damage (see blog post from June). While the shingles were off and several plywood sections needed to be replaced, we had the contractors (my cousin's business Triple L contruction) insulate the attic. We brought the insulation level from R19 to over R40. This made a big difference in the energy needs of our house! It has felt cooler in the summer, and retains heat better thus far in the winter. Our windows are another story...single pane from 1969. Beautiful to look out of over the wooded landscape, but terrible in terms of energy efficiency.

In addition to the extra insulation, we also started to seriously consider using wood to help heat our home. Propane prices have increased greatly, along with all other fossil fuel prices. I don't think we'll ever see fossil fuel prices go back down. They are certain to increase greatly over time. The total price we pay now for LP each heating season has tripled in the 8 years we've been in the house! This, despite keeping nighttime temps quite low, and daytime temps low when we are not in the home during winter week days. We had installed a programmable thermostat which made things very convenient. However, we do live in a woods and do have some access to dead trees we could consider for heating our home.

Our ancient fireplace insert is quite small and not very efficient. It adds some ambiance and does help warm part of the living room area. After researching outdoor wood furnaces that can heat the home and the water we would use, we decided the $10,000 + investment was not the best choice at this time. We found an indoor wood burning furnace that will integrate with our current gas furnace for the best of all worlds. It is also EPA approved for efficiency (up 76%) and low emissions. We spent a lot of time working on the installation...and it still is not completely electrically installed. Beth has had visions of me as the father on The Christmas Story, going to the basement to kick, scream, and cuss out the furnace on a daily basis. The directions are very vague, and looks like we'll need to hire an expert to get it compeltely hooked up and running properly. It's really, really hard for me to admit defeat. But, I think we need to call in an expert before I get socked to death.
This has not deterred me from USING the wood furnace. Other than one day where the gas furnace malfunctioned and continously heated the house to about 85 degrees, we have not used any lp gas this season. The wood furnace does take more oversight, but I've been really impressed by how much heat and how long it will burn a load of wood.

The other aspect of this is that I need to get out there and cut, haul, and split wood a LOT more. this is a lot of time and muscle required, but also is good honest work (and might help keep me in shape). It feels good to know I can gather the necessary resource for heating our home locally. The trees are a renewable source of energy, as long as we harvest respectfully and utlize this sustainable source responsibly. On the economic side, I've estimated we'll save over $1,000 dollars a heating season (typically Nov - April) with the wood furnace. This is a big savings, and will basically pay for the indoor wood furnace in three years! Beyond three years, the savings will accrue.

I know not everyone can heat with wood, but it is an option that may end up being one of the better ways we can locally source our energy for heat. One of the best things we can do in current times is to re-forest the landscape. Trees do an incredible number of functions to made ecosystems healthier and more stable, and provide many useable products in the future. It used to be that a nation's wealth was accounted for based on the health and spread of its forests. With the vast increase in wood burning technology and efficiency, and if you have access to a wood lot, and research what you are doing, it can be economically and environmentally sound.
