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

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.







And here it is with all of the work complete:

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.


The rest of my installation!



Horrible Experience with Square Enix and DIgital River - Review

by filip 7. March 2014 09:11

It could have been worse, in that my order could not have arrived. It did arrive, although almost 1 month late and after I spent hours of my time on the phone with Digital River customer support (and many email threads).

Feb 10th, 2014

I pre-ordered Final Fantasy 13-3 Lightning Returns from the Square Enix online store, which is powered by Digital River. I had already heard of how bad Digital River can be due to their complete screw-up of the Ni No Kuni Collectors Edition. However, since that had happened about 1 year prior, I thought that they may have already fixed their problems.

Right off the bat I should have known that something was not right. It took me about 30 minutes to register an account. I registered with my normal email, but some error occurred during registration. When I tried to re-register, it told me that the email was already in use. However, any attempt to log in (or do a password recovery) was not successful. I was asked security questions in the password recovery screen, however, I never answered these security questions when I created my account in the first place. I had to abandon that email, and try a different one. The process failed again, with the exact same password recovery problem. The third time worked.. I suppose it is a good thing that I can make unlimited aliases for my email address.

Final Fantasy 13-3 Lightning Returns CE was $90, which is $10 less than would qualify for free shipping from Digital River (they wanted about $10 for the shipping charge). Instead of paying for their overpriced shipping, I decided to add a Cactuar Plush to my order so that it would ship for free. I had wanted to add other items, but they were all out of stock, and the Cactuar was in stock.

Feb 11th, 2014

The game was supposed to be shipped. Instead, I get an email that the Cactuar is back-ordered and my entire order will not ship because of it. I really don’t understand why they handle it like that. All of the other stores I’ve ordered from online will ship the items as soon as possible… except for Digital River.

Instead of waiting for the Cactuar to come back in stock, I quickly called their customer support department (by the way, their web site is a complete disaster to navigate if you need to get some help). I found their phone number in a comments section on a blog, as their own website does not seem to make it available (FYI, it is (866) 585-3251). The CSR confirmed that the product was on back order, and she did not have an estimated shipping date. She suggested that I cancel the Cactuar Plush from my order and that will cause it to ship in the next 1-2 days. I instructed her to process the cancellation, and I could verify that the cancellation request appeared right away on my order on Digital River’s site.

Feb 14th, 2014

Three days have passed and the item has not shipped. I called their customer service again. They tell me that the order has been sent to the fulfillment agency and that it should be shipping very soon. Also, they tell me that there isn’t anything else that they can do at this time.

Feb 17th, 2014

Three more days, and no update on my order. At this point, I cannot even cancel it and order a new one since the game is sold out. Instead of calling, I use their email feature online to ask about my order, since the phone attempt was not very successful.

Feb 19th, 2014

It takes them two days to answer my email. The tell me the exact same thing as the phone support 3 days earlier:

Thank you for contacting the Square Enix online store. We show that your order is complete, and it will be shipping soon. You will receive a separate shipping notification email when your order ships. We suggest to check your inbox, spam or junk mail folders.

Feb 24th, 2014

Five more days pass, and the order has still not shipped. It is now 2 weeks after my order date. I send them another email asking them about the status of my order.

Feb 25th, 2014

I get a response back from their customer support:

Thank you for contacting the Square Enix online store. A request has been submitted to cancel cactuar from your order so that the Final Fantasy XIII will be shipped.
However, the cactuar was not successfully cancelled. A follow-up ticket has been created for this issue and you should receive a response within 2-3 business days. If you do not receive any email in your inbox, please check your junk or spam mail filters. As soon as the backordered item is cancelled, your order will be promptly shipped.
We apologize for any inconvenience this may have caused.

Not cancelled? What does that mean? The cactuar has been in stock for probably a week now. So my order cannot ship with the cactuar, and it cannot ship without the cactuar?

Feb 27th, 2014

Two more days pass and nothing. I send them another email.

Feb 28th, 2014

I get an email that the Cactuar has now been cancelled. So it took them 17 days to cancel an item from my order…

Mar 2nd, 2014

I finally get a reply to my email from the 27th:

Thank you for contacting the Square Enix online store.
We apologize for the inconvenience this may have caused you.
We show that your preordered FINAL FANTASY Series Plush CACTUAR [2014 Ver.] was already cancelled. Your order will be shipping soon. You will receive a separate shipping notification email when your order ships.

Mar 3rd, 2014

Shipping confirmation! Its only 3 weeks late, but they’re actually shipping my order. The order is shipping from near Indianapolis, which is about 90 minutes away.

Mar 7th, 2014

I need to drive to the post office to pick up my order. The tracking says that the delivery was attempted yesterday but no one was available to accept the order. This is shipping to my place of work and there are about 20 people working at the time the delivery supposedly happened. We also have security cameras that show that no delivery was attempted. However, I’m able to retrieve the package from the post office.

I still cannot understand why this process is so difficult. I would gladly pay $20 more for the game if it was to be delivered from somewhere like Amazon and I could be fairly certain that it will arrive on the day it is supposed to (I have yet to see Amazon mess up a pre-order, although I’m sure it has happened to others). At least Amazon’s customer service is great.

I suppose I should be happy that I got the game. During the weeks it took to ship, I did lose hope. But this could have been so much easier had Square Enix not used Digital River and stuck with Amazon, Newegg, or even Gamestop.

I would never recommend for anyone to use this store.


jQuery 1.9 and UI 1.10 tabs with cookies

by filip 31. January 2013 15:19

Seems like jQuery UI got rid of maintaining state with the latest implementation.

Before, it pretty simple to keep state across page loads with jQuery tabs. This is one possible way to do it with the new code.  Its still pretty easy, just a little different.

    activate: function (e, ui) { 
        $.cookie('selected-tab', ui.newTab.index(), { path: '/' }); 
    active: $.cookie('selected-tab')
