Thermostat Statistics via Logs for Honeywell Prestige IAQ 2

by filip 21. November 2014 06:00

I created a log viewer for my Honeywell thermostat. In addition to providing a much more friendly way of viewing log files, it aggregates logs over time allowing for some pretty neat analysis.

Detailed Geothermal Analysis in Cincinnati, Ohio

by filip 19. June 2014 02:49

The following numbers are all in kWh, and for my single-family house that is about 2,000 square feet, plus basement. All heating is electric. My electric bills usually come in around the 17th to 20th of the month. In the data below, an October value is actually the usage from the second half of September to the first half of October. 

The data is current as of 5/24/2017. I'll try to update this monthly.

kWh Usage Details, Monthly

Below is a breakdown of my monthly electric usage since late 2007. The gray cells is my usage when using an inefficient air-source heat pump (probably 10 or 11 SEER). The green cells is my usage since installing a geothermal heat pump.

kWh Usage, Monthly Average

Here is a summary of the above table. The grey cells is the average, per month, of the grey cells from the table above, and the green cells are the average, per month, of the green cells above.

  Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec
Air 4,578 4,656 3,343 2,096 1,263 1,276 1,435 1,363 1,523 1,169 1,580 3,304
Geo 3,277 2,433 2,007 1,487 1,109 1,273 1,464 1,526 1,454 1,170 1,273 2,339

In the summer months I'm obviously not really saving any (significant) money, even when compared to the 20-year old, inefficient air source heat pump. I never did use much electric (for cooling) in the summer months though.

Based on the "Monthly Average" data above, I'm saving about 6,379 kWh per year. At my current electric rate of about $0.10 per kWh (it varies slightly month-to-month), the yearly savings from upgrading to geothermal is $637.91. This translates to a 23.5% savings per year over my previous electric bills.

When I purchased my geothermal unit, my existing heat pump was broken. I received various estimates for replacement - the average of which was around $8,500. The final cost of the geothermal heat pump from Arronco came out to be around $13,500 after tax credits and rebates. If I assume that a new air source heat pump would have similar performance to my old air source heat pump (which probably is not a good assumption), the return on investment would be roughly 8 years. However, since a new air source heat pump should be more efficient than my old air source heat pump, I'm guessing that a more realistic ROI would be closer to 10 years.

Arronco Geothermal Installation in Cincinnati Part 2

by filip 23. April 2014 02:42

This is a follow-up article to my initial article about my geothermal installation.

For the past couple days, Arronco was finishing up their geothermal installation in my house. The first day was spent on removing my existing unit as well as setting up the Byrant geothermal unit (GT-PB). The second day was spent on finishing up the GT-PB install, hooking up the tubes that run outside to the unit, attaching my water heater to the geothermal unit, and finally setting up my thermostat.

The first set of pictures is some of the work outside of the house.

My Arronco Geothermal Installation in Cincinnati

by filip 18. April 2014 17:19

It was time for me to replace my heat pump, and I got a few bids from local companies. I ended up setting on a geothermal system from Arronco.

They came out yesterday to drill the wells where the tubes will go. The first thing to show up was the tubing, delivered by a local delivery company.

Geothermal tubes. Each is about 510 feet long.

After that the Arronco geothermal truck showed up.

Arronco Geothermal Truck

The guys put down some rubber mats on the lawn so that the tires don’t damage the yard too much. It still ended up tearing up my yard, but I don’t really see how they could do it any other way. They also had very little space to work with as it had to fit between the driveway and the electric box in front of the house. The weight of that truck would have probably cracked my driveway.

Path for Geothermal Truck

Once everything was set up, they got the truck in.

Once the truck was in place, they put the big digging arm up and started digging the first of two holes. Each hole was to be 225’ deep.

The entire process is very loud, a kind of messy (although a lot less messy than I thought it would be). Here are some more photos of the entire process. The white stuff is ground up limestone that started coming up once they got like 30’ below ground.

After they left, I was left with the following in my yard. They’ll be coming over on Monday to install the unit inside, and on Wednesday to dig the trench that will connect the tubing to the inside.

Adobe Creative Cloud Subscription for Business Catalyst Website

by filip 21. June 2012 09:40

We recently got the Adobe Creative Cloud subscription at work, and I wanted to check out their web hosting plan – one of the features is hosting for up to five websites.

Step 1: Creating a Website

I’ve never hosted a website with Adobe (or, more specifically, Business Catalyst), so I wasn’t sure where to start.  I looked around the website, and eventually found that there are three ways to create a website:

  • Muse: an Adobe program for non-programmers to create websites
  • Dreamweaver: an Adobe program for programmers to create websites (last time I used this was maybe 12 years ago)
  • BusinessCatalyst.com: an online management tool for websites

The documentation I read on Adobe.com indicated that even if I go the Muse or Dreamweaver route, I’ll eventually need to use BusinessCatalyst to manage my site for things such as DNS, so I went to BusinessCatalyst.com.  Also, I didn’t really feel like installing Muse or Dreamweaver, as I have no intention of using either of those programs (I like to use Visual Studio for those types of tasks).

Well, turns out that creating my website with BusinessCatalyst.com was a mistake. Creative Cloud subscriptions come with five webBasic websites. These types of websites can be created from Muse (or possibly Dreamweaver).  However, creating from BusinessCatalyst.com will create a webCommerce site. I noticed the problem when I tried to promote my site to live. When clicking the “Upgrade” button, it started asking for my credit card info. After a chat with their CSR, my site was “downgraded” to webBasic and I was able to push the site to live.

Step 2: DNS – Creating a Subdomain

I did not want to move my website to Business Catalyst. What I wanted was a place to store files on the Adobe Cloud, while keeping my website where it was.  To do that, I wanted a subdomain, images.bloodforge.com, to be hosted on Adobe’s cloud. Everything else with bloodforge.com would remain where it was.

The first step is to go to the administration section of the website created in Step 1 above, clicking on Manage Site-> Site Settings –> Site Domains. Click on “New Domain” button on the top of the page, and configure the domain. In the “Domain” field, enter the full domain name of your site. So, in my example, I entered “images.bloodforge.com”, without the quotes. Select “Use an external DNS server” radio button option, and copy the IP address listed. You will need this in the next step.  Click on the “Save” button.

Now that you have the IP address of your site, log into the DNS manager of your current website (which in my case was Arvixe, but it could just as well have been GoDaddy or something similar.  You will need to create an “A” record for your domain, and point it to the IP address you just copied from BusinessCatalyst when creating your domain. So, in my example, I created an “A” record for "bloodforge.com” with a name of “images”, and pointed it to the correct IP address.

At this point, you should be able to go to the domain you just created. Type the full domain (in my case, images.bloodforge.com) into your browser and you should now be at the BusinessCatalyst website.

Step 3: FTP files to your Adobe/Business Catalyst website

You’ll need to obtain the FTP settings for your website from BusinessCatalyst. Log into the admin section of the website created in Step 1, and go to “ManageSite” –> “Site Manager” –> “File Manager”, and click on the “Upload Files” button at the top of the page. There should be a Tip on this page, and if you click on the “See Details” button, it will show you the details for your FTP login info. In my case, it was:

  • host: images.bloodforge.com
  • username: images.bloodforge.com/{Business Catalyst username}
  • password: {Business Catalyst password}

I use FileZilla to FTP, and I entered in the information above. I was rather disappointed that BusinessCatalyst used standard FTP with plain text encryption. Doesn’t seem very secure, but it is what it is.

I was able to upload “.aspx” pages to the site, however, it did not execute. Seems like the handler for the file types is disabled. However, other files, such as images, serve up just fine. One thing to keep in mind is that if you upload HTML files, they will not be exactly the same when you access them with a browser. BusinessCatalyst adds some of their own stuff into your files.
