Cool and Smooth

I started bright and early on installation of our new solar attic fan.  I wanted to get it done before the heat of the day set in.

The first thing I had to do was remove the cover of the old fan.  While I do not have any pictures of it, it entailed removing some shingles and prying it off the roof.

I then had to replace those shingles I had to remove to prepare the hole for the fan.

As you can see, the top half of the hole has been removed completely of shingles and roofing felt.  I then used my reciprocating saw and pry bar to loosen and remove any nails in the vicinity of where the flashing of the unit goes (underneath the shingles).

Now it was time for some test fitting.

As you can see, the bottom half of the flashing is above the singles.  This is how the instructions said to install.  It took a few times, but we finally got it.  The major pain was the fact that the fan is so close to the peak of the roof.

I then applied some roofing sealant, some call it tar to the underside of the flashing from the 9 o’clock to the 3 o’clock positions.  I ran 2 beads of it for an extra layer of protection.  I then slid it right back to the same spot.

I then nailed the unit in place as the installation instructions recommended.  Then I applied roofing sealant to the areas where I nailed the fan into place.

That’s it!  It was running before I even had it fully installed.

I was very surprised that it only took me about 2 and a half hours to fully install this fan.  I dread any work on a roof, but this went as smooth as can be.

Many thanks goes to my dad for helping me with this one.  It’s much easier to pass things from ground level to a roof with another person.

Now hopefully our attic will stay cooler, our energy bills will be lower, and we will have no leaks.

The next solar project we are discussing is water heating.  It’s hard to decide on what type of system to decide on.

Solar Power Here We Come

Our 34 year old attic fan has basically bit the dust.  The bearings have just went kaputz!

As I wrote previously, we are replacing it with a solar attic fan.  Rachel and I did some research, and decided to go with a Attic Breeze – Model AB-201A.

By far it’s largest draw is a lifetime warranty.  Most other models have between 5 to 10 year warranties on the working parts.

It is coming from Texas, and I’m expecting it’s arrival within a week or two.

I will post energy saving figures and installation pictures as soon as possible.

Letting The Numbers Speak

I have been keeping a log of all of our utility usage and costs this year.  I’m hoping to drop our electricity usage by a meager 2% per year.  I don’t want to start large and disappoint myself.

My logs for other utilities, such as water, sewer, telephone and cable haven’t been as closely monitored because I seem to can’t find some of the statements.

Our home is a total electric home, so it is easy to disseminate our total usage.

In 2007 we used a total of 17,712 KWH (Kilowatt Hours) of electricity.  We used an average of 48.9 KWH per day, which cost us on average $4.90 per day.  On average one KWH of electricity cost us $0.10 in 2007, and we paid $1,777.41 for electricity in 2007.

How do your numbers look in comparison?  I really don’t know if ours is bad or good.  So if you are a dork like me and like to keep track of things such as these, perhaps I can get some information to set my household on a track to help this earth, instead of harming it.

I’ve spent the past hour trying to get information on “average household electricity usage” but the DOE’s website is junk, and I can’t find anything else useful.

Green Power For The Masses

Finally electric consumers in this area have options when it comes to how the power they consume is generated.

The Herald-Times had a story on October 4th that blew me away.  All of the local electric utilities (Duke Energy, UDWI-REMC and SCI-REMC) have an option now, where you can ensure at least parts of your electric consumption are from renewable sources.  They lised biomass, wind and methane from landfills as examples.

It is purchased in 100 kilowatt blocks, which in my case cost $4.  This is in addition to your normal usage bill.  We are UDWI-REMC customers, according to their form, you can purchase as much as you desire.

Our average electric bill is around 1200 kilowatts.  We are discussing purchasing around 400 kilowatts to lower our carbon footprint.  We might purchase more eventually.  I do want some proof before I commit though.

That’s only $16 more a month!  True, we will still be using coal produced electricty primarily, but we will be using 1/3rd less “dirty power.”

The other options aren’t cheap!  A whole house solar array starts at around 20k, adequate wind turbines are about 50k.  Smaller systems are not that much cheaper.  That’s not in my budget right now.  When the time comes for a new water heater, we are still considering solar, which could save thousands in the long haul.  Solar water heating systems are only around 3k though, much more feasible.

With our new heat pump, our electric bill has been reduced significantly, but I know we can do more.  This is one step in the right direction.

If only the rest of the country, or heck 10% would get out of their Hummers and give it a thought, Earth might be a far better place in the future.  Don’t even get me started on these college students with the Uber-SUV’s that they don’t need.

Letting The Numbers Speak

To help us determine ways to save energy costs and consumption, I have created spreadsheets of our utility bills and a spreadsheet for the fuel consumption of my truck.

From what I have entered thus far I have found some very surprising facts.

I believe there is something “fishy” going on at our water company, as the numbers just don’t add up.

Here’s an example:

In March, we were billed for using 1980 gallons of water, which we were charged $9.43.  A month later, we used 1990 gallons and were charged the same amount, $9.43.  Our sewer bill shows this same descrepancy as we were charged $46.00 each month.

What’s 100 gallons of water and sewage when you’re only being charged 1/2 cent per gallon for water and 2 cents per gallon of sewage?

Here’s the amazing thing.  The installation of our new heat pump has significantly reduced our electric use.  Here’s the numbers:

Billing Date     Total KWH Used     Avg. KWH/Day     Total Charges
   3/5/07                   3023                     107.96                $261.94    
   4/4/07                   1379                       44.48                $138.55

The first set of numbers are consumption prior to installation.

Our home is powered completely by electricty.  We are using more and more energy conservation methods, and when something needs replaced we always look at how much it consumes before purchasing.

Hopefully we will get that new solar attic fan I wrote about before sometime soon.  We are even discussing purchasing a tankless hot water heater, when the time comes.  Electric models require much more infastructure than gas ones, but are still just as good.

How does your household rate?  I read somewhere that the “average” US household uses 1000 KWH per month.  If we could drop the average by 1%, we would be doing the world more than we know.
