Geothermal Phase 1

We have heat! Well, we’ve had heat – when we were house shopping, fireplaces were a big thing to some people. Kind of a ‘whatever’ to me – not like I’d refuse to consider a house because of a fireplace, but I didn’t care if there was no fireplace either. The house we purchased has this Lopi Freedom Bay wood burning insert. More of a curiosity to me when we were house shopping, but it’s allowed us to make non-hasty decisions about HVAC equipment twice now. We got a super high end (and super expensive) air exchange heat pump in November of last year. It didn’t work well for us — 20kW of heat strips kicking in for a few months gets expensive. The service from the company that installed it, however, was right abysmal. Things we reported in November of 2015 were still unresolved during the summer of 2016. And, yeah, we could have been ringing them every day to force some action … but few of the issues were worth that level of effort. The thermostat software locks & the system is in the state is was at lockup (i.e. you wake up shivering in mid-summer because the AC has been running full-blast for hours). It reboots and works for another month or two. The air handler leaked. Until they patched it and our lower level got ten degrees warmer, I didn’t realize how MUCH it leaked. The list goes on. We’d bother them every month or two, sometimes get some action and sometimes not. The installer, though, had a one year 100% satisfaction guarantee. Without a bunch of fine print or conditions. Which, really, is why I was OK getting an air exchange heat pump from them.

On several levels, we were not satisfied. The company tried adding some conditions to their written guarantee after-the-fact, but they eventually relented and removed the system from our house and refunded the full contract price. They were not, however, able to restore us to the original condition … not that I wanted an old gas Trane with a cracked heat exchanger … but the circuit breakers and copper wire they pulled would have been nice. They were willing to leave the NEW circuit breakers and wiring in for the > 900$ line item from their bill. But, seriously, 200$ of stuff from Home Depot is not something for which I’m keen on paying near a grand.

Initially, I wasn’t sure how much more a geothermal system would cost … until we got some quotes and discovered that we could get a fully variable geothermal system for 500$ less than we payed for the air exchange heat pump. WOW! The configuration we chose ended up being 100$ more – we added an additional 200′ bore. Because it is going to take about three weeks before the drilling can commence, they installed the HVAC equipment without connecting it to the earth loops & set it up to run in emergency heat mode — which is essentially a really expensive 20kW electric heater. But it keeps us from freezing when the fire goes out overnight 🙂

I is for … huh?

There’s political correctness and then there’s silliness. Anya’s preschool newsletter said they would be introducing the letters “H” for harvest and “I” for Native Americans in the first half of November. Wait, “I” for Native Americans? Took me a second to realize that they mean Indians. To some extent, I get removing controversial terms – especially at a young age where you just don’t want to get into the discussion around why some people find whatever-it-is to be offensive. But why wouldn’t they pick another word for the letter?! Ice, Ink, Inside, Incredible, Imagine, Infinite, Island … thousands of words that start with ‘i’.

Introvert, Extrovert, And Somewhere Inbetween

I’ve found myself researching how introverts deal with raising an extroverted child. I have no idea how that combination manages. I am not a introvert. I abhorred quiet – my office space was silent most of the day, and I would blast music so I could concentrate. Living alone, my house was quiet — I’d go out with friends after work, come home and turn on music or ring someone up to chat. I got enough quiet in half an hour before bed and a dozen quick walks (outside for the mail, across the car park at the office, etc) to be happy.

Living with another adult reduced some of the quiet times, but not enough that I minded. Having a young child, however, has almost completely eliminated quiet from my life. Relatives purchase loud toys — and laugh about it, knowing exactly how much the kid is going to adore creating cacophony. I feel bad about taking away a beloved toy (or ripping the batteries out of the damn thing), but seriously the ONLY time Anya isn’t talking … she’s got some toy blaring, or the TV is on, or there is some other assault on my ears.

She’s had a few experiences with boys at the playground who were a few years older than her, and VERY rough in their play. She hates it – to the point she’s happy to leave the playground. I’ve tried explaining to her that those boys were putting out a lot more energy than she wanted to deal with. And I feel the same way about her sometimes — I see that you are having fun, but it’s just TOO MUCH. She gets it, and then turns on one of the singing race cars.

I found a lot of articles / blogs / etc from the standpoint of an extroverted parent trying to raise an introverted child — but an adult has the capacity for abstract thought. You can be quiet for someone else. An almost four year old … not so much. My mom used to have enforced quiet – turn off the lights, fire up a few candles, and just relax. Hated it to the point that I, twenty-five years later, cannot imagine forcing such horror on our child … no matter how practical the solution might be. Unfortunately the only other solution I can see is being somewhere else for a few hours each week.

Change

There are a lot of areas where the trend oscillates between two states. “Cloud computing” is somewhat new and somewhat trendy, but the “computers are expensive, bandwidth is cheap … centralize everything” and “computers are cheap, bandwidth is expensive … distribute everything” states haven’t changed. A VAX with its terminals or a Citrix farm with its thin clients. Better graphics today, but conceptually the same thing. The difference is marketing — I don’t believe they pushed VT100’s for the home market. SaaS has personal targets as well as commercial.

With these changes, there were winners and losers. Mainframes lost market-share as companies deployed desktop PCs. And now desktop PC vendors are losing market-share as “cloud” services become prevalent. Sucks on an individual level — for, say, the people IBM laid off as their mainframe business contracted — but it wasn’t the driving force behind a political movement.

Manufacturing moved overseas. Energy production moved overseas. Some manufacturing (electronics, for instance) are harder to bring back — we simply lack the knowledge and equipment to pick up manufacturing electronics. Beyond that, though, it is hard to compete with someone who can continually undercut you on cost. You can slap import tariffs on everything you see, but the Chinese government can force employees to work for less. And who wants to start paying MORE for the same stuff? That’s the other side of import duties that people fail to talk about — sure we can jack up the price of ‘stuff’ that comes in from overseas so domestically produced items are competitive … but unless you’re getting a serious raise to go with it, that means items become less affordable. Apart from political change, some manufacturing is apt to move back to personal production (i.e. I’ll 3D print any cheap plastic junk we used to ship in from overseas). And that will negatively impact some of the BRIC economies. The move to personal production may benefit American companies — they design the products, license out the print file, and you make it (or use the 3D printer at your public library to print it, or go to the 3D document centre at Staples).

Until about 3AM today, I thought we’d be seeing a similar apolitical shift in energy markets. The renewable energy tax credits got extended in a Congress where even the trivial faced unimaginable opposition. Personal energy production makes electric vehicles a lot more enticing — paying 20$ a week to the petrol station or 20$ a week to the electric company … not much immediate, tangible benefit. But using the electricity that I’m producing v/s paying 20$ a week to the petrol station – that’s a whole different story.

That shift had worrying geo-political implications — the Middle East isn’t stable, but the area is useful and there’s incentive on both sides to maintain some semblance of order. As demand for oil shifts, incentives change. Odd, to me, that someone who wants to levy tariffs to make American products competitive doesn’t agree with leaving tax incentives in place to promote domestically manufactured clean energy solutions. “Clean” coal, sure … but don’t give ’em a tax incentive to buy solar panels manufactured out on the West coast.

 

 

Toddler Closet

I used a tension rod to create a toddler-accessible closet. I plan on raising the bar as she gets taller.

I got hangers that have clips for slacks/skirts, and each hanger holds an outfit. Her pajamas, daily clothes, and gymnastics outfits are all available. Anya *LOVES* having her clothes in her closet.

Real People

When I was in college, I went out to a bar with some friends. They had a friend, who had graduated a year or two previously, visiting; this guy came out with us. This friend-of-a-friend and I were sitting at a table while everyone else was getting a drink, and the guy said he wanted to meet a beautiful girl like me … but he doesn’t know how to approach one. What, he asked me, would be the best “pick up line”? To which I quickly answered “Hi, I’m Eric”. Why is speaking to a cute girl different than talking to any other human being?

I subsequently learned that, indeed, young attractive women are treated a lot differently — the sort of things people assume are acceptable make the 2005 ‘grab them by the pussy’ recording … well, not surprising. My office at the University had been a photography darkroom. It had two separate rooms — an antechamber and the darkroom part. A friend of mine and I were in the darkroom part, and she was on the phone with someone. Glenn, one of my work-study students came in to speak with me. Not wanting to interrupt her conversation, I asked him to come into the antechamber. He proceeded to back me into a chair, physically restrain me by sitting on me, and kiss me on the mouth. My rather loud entreaty for my friend to come into the other room was met with an annoyed “I’m on the PHONE”. Luckily she finished her call before the student got beyond unwanted kissing, and he backed off when he heard her walking.

And to people who say “but no one reported it happening, so it didn’t happen”. I didn’t report the student either — there’s no evidence. There’s nothing beyond my say-so. And I’m sure he’s going to say it never happened. And that’s a scenario where I at least knew the person. Random guys at a club who take similar liberties — how would that work? Gently move his hand from my crotch to the table, then ask for his name and number? Remove yourself from the situation, and make sure a friend stays close to you at the club — that was my realistic solution.

Non-solutions

This post takes as a priori knowledge (i.e. not something I necessarily believe to be true based on my experience) that white flight is still a thing – that African Americans primarily live in urban centers – and that these urban centers are an absolute wreck of violent crime and disintegration.

I’ll admit to being advantaged by a lot of implicit bias — I’m a grown up white person. A female, though … and a female in science/technology fields … so it is something I’ve experienced occasionally. The first major company for which I worked, a top-level manager in the IT org hired in a lot of his at-the-time girlfriends. The new girl showing up was assumed to be incompetent, and it is a lot harder to convince someone of your competence if they start out knowing that you are only here because you are sleeping with the boss. Frustrating, but nowhere near the level of “the cops got called when I was standing at my front door trying to find my key”.

My specifics don’t give me a lot of understanding of minorities who suffer implicit bias, racial profiling, and outright discrimination … but I cannot fathom how “stop and frisk” is meant to solve either problem. Even if 25% of the people who live here are degenerate criminals, 75% of the people aren’t. Statistically you spend a lot of time hassling innocents — who may well not consider it a worthwhile trade-off to eliminate one burglar.

The nearest analogy in my life-experience is DUI and seat-belt check-points. I remember being late to work one morning because a seat-belt check-point was on my route. Slowed down traffic quite a bit, stopped on the queue waiting for my turn. Plus it took a couple of minutes for the check itself (they were doing about the nosiest check-point I’d ever seen — basically taking as much time as they could to peruse the plain-sight contents of your vehicle, asking questions, etc). There’s a sanctity of human life argument that says that the potential to save one life has more weight than a hundred people being delayed for twenty minutes that morning. Which, as a one-off … whatever. How many times, though, could I be detained before *I* don’t care all that much about the life of some goober who intentionally refused to fasten their seat belt.

And there’s a difference between reducing and relocating crime. New York City got very “tough on crime” and was able to reduce crime significantly. But Philadelphia saw a dramatic increase in crime — NY didn’t stop people from committing crime, they just stopped people from committing crimes *in NYC*. I don’t see stop-and-frisk having the slightest chance of reducing crime. Relocating, sure, but not reducing.

Geothermal Pricing

I’ll start out with an acknowledgement that what makes this comparison so shocking is the 30% federal tax credit. A straight comparison of a super high-end HVAC system with a geothermal system will be a completely different scenario if the tax credit expires.

Last year, we got the top of the line air-exchange heat pump. And we’ve had a lot of problems. Installation problems, air leakage problems, thermostat problems … all compounded by terrible difficulties getting service people out to sort the issues. And at the end of the day, the house isn’t comfortable. The “this is the only thermostat you can use” thermostat … well, first off all freezes up every now and again and the system is either ON or OFF at the time and stays there. But from a firmware / logic standpoint – there is nothing that looks at the relative humidity in our house and says “hey, we should drop the temperature set-point a degree or two to avoid living in a swamp”. Which wouldn’t be a problem if we could tie the thing into OpenHAB. But we cannot.

The system came with a 365 day 100% satisfaction guarantee … which, really, was the reason I was OK with installing it last year. Worst case, we ask for it to be removed & the entire contract price gets refunded. Well, we are not satisfied … but that means we’re back to shopping for an HVAC system.

I researched geothermal system manufacturers. Evidently there are only a few actual manufacturers whose product is sold under a lot of different labels. I contacted local installers to get a quote for each of the major systems I found. My expectation was that a geothermal system would be a couple thousand more than we paid for the air exchange heat pump once you take off the 30% tax credit money.

We got our first quote today — for 600$ less than the air exchange heat pump. It’ll be more to do vertical bores instead of horizontal bores, but that’s a decision to spend money for efficiency. I expect vertical bores will take us into the “couple grand more than we paid” territory. But I don’t see the point of high-end air exchange heat pump systems up North here — a two-stage geothermal system is going to be quite a bit more efficient, not engage the backup heating as often, and cost less than the top of the line variable speed air exchange systems.

The HVAC company that installed our current unit had horror stories of people having to rip out entire yards because of leaking tubes … but, thinking about it without needing to make a decision now … I suspect those are older installations. So, yeah, we have the possibility of leaking lines twenty years from now (lines are warrantied for 50 years, but you are still paying labor). And that would totally suck, but do I really expect the air-exchange heat pump sitting outside is going to be in service twenty years from now?

The price of an egg

Pricing can be amusing – I always thought the 6$ roasted chicken at markets is 3$ chicken with today as a sell-by date. Toss it and you lose money, cook it and you charge more for it.

We recently stopped at McDonald’s during a marathon shopping excursion (and hungry/cranky tiny people are *not* good shopping partners). Don’t know the menu, so we went inside to take our time ordering. Sausage McMuffin = 1.29$. Sausage McMuffin With Egg = 3.29$. Umm, an egg costs 2$? An entire *dozen* eggs doesn’t cost that unless you want the “free range” “organic” ones from a major chain grocery store. A dozen from the guy down the street (fully free-ranged hens, but not certified organic) only costs 2$!

I know that pricing is determined by perceived value and demand. And the cheap sausage/cheese/English muffin option is included in the tiny ‘value menu’ section while the expensive sausage/egg/cheese/English muffin option is a huge menu tile in full color with a picture so a lot of customers (especially those in the drive-through who may not feel comfortable parking long enough to read the entire menu) may not even know the other option exists. But where else does a single egg cost 2$?!
