  1. Re:Nest & Tankless heater on Ask Slashdot: Shortcuts To a High Tech House · · Score: 1

    Ah I see. My tankless is natgas powered, and they locally store more than a days worth, so that did not cross my mind.

    I have seen the system design where you a large thermal solar tank storage feeding into a electric tankless, which strikes me as a pretty good design.

    The one saving grace is most of the tankless heaters I've seen draw similar power to a air conditioner. So a house with tankless and air conditioning, draws 50 amps at 5am for a couple minutes, then more and more power until running darn near continuous 50 amps around 3pm for the air conditioner, then declining etc.

    Also all the houses in my neighborhood simultaneously run full out air conditioning at 3pm on the hottest day of the year, but the phase variance in lifestyles is pretty large, so my entire neighborhood probably only draws one heater at a time.

    In a non-air conditioning wired neighborhood, your example Could be an issue.

    If, as you say, money is a problem and you're on a budget, you should obviously drop any wild plans. Look for quality instead of tech,

    Or, if you assume, as most people do, that your life of freedom and fun is over once you get married and get a house, you'll probably have a lot more spare time, and a hell of a lot more space, so go ghetto and spend enormous amounts of time building it yourself out of cheap junk.

    Priced as an "extra luxury item" a large digital picture frame is Very expensive. But an old used PC, and a low end multi-monitor video card, and a cheap desktop monitor with a wallmount, results in a cheap large digital picture frame.

    Just like if you want automation, you can stick misterhouse on the existing fileserver for "free" and cable it to your X-10 or insteon bridge which costs damn near free, or you can pay $2500 for basically misterhouse installed in a turnkey appliance box. I'm sure I could buy an automation appliance that costs $3000 but instead I spent $29 on my insteon bridge years ago and plugged it into the existing file server.

    Similar to the automation, I eased into mythtv by piggybacking on the fileserver. My first frontend was a plain old $50 desktop living in an adjacent closet. If you want, you can do something like mythtv by spending thousands, but I spent tens instead.

    If you live in an apartment, and you do electronics, and you determine you need an oscilloscope, for storage reasons a kilobuck handheld digital scope might be your only reasonable choice. If you have an empty basement, a filing cabinet sized old tektronix that weighs 150 pounds is A-OK and only costs $50 at a ham radio fest.

    no rapid filling of bathtubs or buckets, or hot water pressure wash.

    I call shenanigans on this one as I have seen no such effect and can't even imagine it happening in the marketplace for sound financial reasons.

    Your plumber, operating on a sales commission, will try to figure out how much money he can extract from you, and then extract it. He was trying to convince me that I need to output water hot enough for instant 3rd degree burns, at full blast, simultaneously out both showers, the bathroom sink, the kitchen sink, the dishwaster, the clothes washer, and the utility sink, all while the input water is at 33 degrees. There are not enough people in my household to operate all those valves at once. Um, no sorry, you're installing something a little more reasonable. Especially since the whole point of installing the tankless was to be able to turn the temperature down below scalding level while not running out of hot water in the shower. This has NOT been an issue in actual operation.

    The scaling rate of price for BTU of heating seems to be somewhat quadratic, certainly not slightly sub-linear like you'd intuitively guess based on construction. So half the BTUs is a hell of a lot less than half the price. At least thats how it was years ago.

    You'll also likely be at the mercy of power outages - even short ones.

    Same problem for tank w/ direct vent. I suppose it depends where you live. Where I live the only reason the power ever goes out is near-tornado conditions... you're supposed to be cowering in the basement under the stairs then, not enjoying yourself in the shower. The power requirement is ridiculously low to run the electronics and fan, so for 7 years now I've been planning on buying a very large computer UPS, but the darn power never is out long enough to make the upfront expense worth it, not to mention having to replace the UPS batteries every 2 years or whatever. I do have a 50 foot (rather expensive) extension cord coiled up next to it that I can run over to the basement server UPS, but I've never had to try it.

    Its kind of like arguing you shouldn't install a furnace or air conditioner because you'll be at the mercy of power outages...

Him and his coworkers all moved into the same subdivision at the same time and helped frame each others houses, then they contracted out for the technical stuff (electrical, plumbing) then my grandmother and friends painted the inside walls.

  6. Plan for a short sale now on Ask Slashdot: Shortcuts To a High Tech House · · Score: 1, Insightful

    about to take on the next big adventure: home ownership

    Bad time to buy. Run like hell.

    1) Multi-generational low interest rates mean they'll inevitably increase. Increasing rates = declining home prices. My parents bought the equivalent of a mcmansion for only $80K (not 8M, not 800K) during the peak of the 70s-80s stagflation when I was a kid, 20% interest rates and all. Needless to say the price exploded as rates dropped to normal. You'll be experiencing the reverse effect as rates increase... home price implodes. If you're planning to live there for the entire mortgage, then you'll merely get a legendarily bad deal, but if you have to move you'll probably be underwater, welcome to foreclosure and bankruptcy.

    2) The % of the population employed has been steadily and permanently dropping. The odds of your being able to make a mortgage payment, every month, for 25 years, is about the same as the odds of having the same job at the same company for 25 years. On a "tech board" like this we know all about ageism... after 40 no one is ever going to hire you to do tech, so you either need to contract or greet at walmart or retrain into ... something.

    3) For at least 40 years the median inflation adjusted income has been dropping. That means the median person's housing budget has been dropping. That means that aside from govt intervention, etc, the price of median real estate must drop. Essentially you're buying an asset whos value is guaranteed to drop over time.

    4) Kids are much cheaper than houses, the payments are generally much more flexible and predictable, and the "contract" theoretically ends at 18 instead of 25 or 30 years. You skipped a step on the plan. Ease into a commitment toward debt slavery. Actually you probably skipped two steps... start with a pet, like a housecat, see if she's all bonkers maternal instinct on the cat, then if its all good squirt out some kids, then do the landed estate thing.

    5) Everyone who gets married thinks their relationship is "special" and "forever" but half of them end up divorced anyway. The odds are actually better than you'll be divorced than you'll be married forever. A house just complicates things, a "high tech" house complicates further.

    Arguments for:

    1) A commissioned salesperson thinks today is a great time to buy. For a good laugh ask your barber how often to get a haircut.

    2) People used to make lots of money buying and selling real estate. Well, they made a lot of money selling horse carriages, and working on industrial assembly lines, and being travel agents. Would not advise entering real estate in 2012 anymore than I'd advise becoming a travel agent.

    So here's the deal. In the long run the price of the house is going to drop. I don't think a fancy thermostat and/or sound system is going to offset that. At some point when you own the house you'll be unemployed and minimizing your expenses (electrical bill, credit card bill, monthly subscriptions) is the key to survival. In the future, even during good times, you'll have less money, either lower bottom line income, inflation, etc. Needless to say, when I bought my house, I was not paying $5/gallon for gas... The majority outcome in the medium term is you'll be trying to figure out what to do with the house at a divorce proceeding.

    Theoretical plan based on the above: Only invest in fixed non-removable stuff that save you money every month. Fancy insulation, triple pane windows, high efficiency appliances. Do not put something "unmovable" into the house, because you'll be removing it a heck of a lot sooner than you think, so forget whole house audio etc. Plug in X10/Insteon stuff, OK. Wired in X10/Insteon, not OK. Ethernet patch cable thru hole in floor OK, permanent house wiring that'll just get ripped out by the next owner, not OK. Never install or purchase anything with a monthly subscription or increased monthly cost because you'll probably not be able to afford it in the f

    What I've read about them says that tankless water heaters wear out faster than the traditional kind with a tank

    LOL. I know its April 1st, but for those who don't get it, try to find a tank guaranteed by mfgr longer than 6 years or a tankless with a guarantee shorter than 20 years. The guy's humor is in stating the exact opposite of reality.

    There is some truth that a decade or so ago when I got a tankless, tanks were for residential and were value engineered to fail rapidly to maximize profit via maximum lifetime cost, and tankless were for industrial apps (think laundromat or health club showers) so they were engineered to meet the business accounting goal of minimum lifetime cost. It may be that 2012 residential-grade tankless heaters are now value engineered and built in China such that they'll only operate for a couple years before requiring replacement... If they aren't, the retailers are missing out on a huge opportunity to screw their customers, and they never miss a chance to do that, at least not for long, so buyer beware. But at least in years past, tank = flood the basement twice per decade, and tankless = buy roughly once per human generation.

    Another way I've heard it phrased is if you go tank, then you need to pick a basement floor covering that tolerates flooding multiple times before the floor material is replaced, but if you go tankless, then you will replace the basement floor covering a couple times before the heater is replaced. It has a big impact on decor... Pergo is legendary for being perhaps the least flooding tolerant floor covering, so you can really only go Pergo if you have a tankless, and/or if you have a tank you pretty much need tile to eliminate the water damage issue.
