    Thank you. I guess I will speak with my future neighbours and a few well drilling contractors in that area to see what they recommend. I have to admit, I like the idea of a small water tank. The ...

    Steve, As far as I know, drilled wells all require the same three components for water delivery: a submersible pump, a pressure switch, and a pressure tank. I don't think that there is a ...

    Thanks Walter I do already have a similar free program of such kind that's used here, but I have a feeling this one might be better :) I will certainly give it a go over the weekend. As a ...

    It really depends on how deep and what GPM you can get/want. But really the only thing that makes a difference in residential usage is the size of the pressure tank, or if you can go gravity that ...

    Thanks Martin. I'll report back regarding results. Yes, I am definitely dense packing 2x10 joist bays. Thanks for highlighting. Regards, Joe

    You should down load a free program called BEopt from the US government. https://beopt.nrel.gov/ It will calculate the energy related costs based your mortgage rate, local weather, ...

    Walter, That's how we fasten all our sheathing now. The boxes of nails just disappear.

    If your part Delaware is in a hurricane zone please be sure to do your home work and be sure you have enough structure to resist any wind that could come your way. As I recall the non ...

    Anon3 : The Trane/American Standard mini-splits look EXACTLY like a Gree Crown in every external detail, and not much like a Midea. What is it that makes you think they are "most likely" made by ...
  • Anon3 | May 24,2017 06:02 PM EDT
    They are all made by Chinese companies (Midea or GREE), there are a couple 40 SEER 9kbtu units coming out 2H this year. Also checkout GREE 2017 catalog, the spec is out already. They probably ...

    I appreciate the links that you provided, Martin, and the additional discussion and link from Dana. (Edited to avoid two separate "thank you" posts.)

    It was ~85F out on the hill @ 7PM when those clips were taken with a hand held still camera operated in video mode (which only enhances the arm waving excitement! :-) )

    That reactor ran for about 40 years, a sufficiently long lifecycle to "pay off" the greenhouse gas emissions of baking all that limestone to make the concrete, among other material costs. The ...

    Even if you go to 36 inches

    Marc, I haven't heard of the method described in your latest post, but I have no reason to think it wouldn't work.

    Josh, The usual definition of a low-slope roof is a roof with a shallower pitch than 4-in-12. Some sources say 3-in-12. So you probably don't have a low-slope roof, and you can probably move ...
  • user-6793320 | May 24,2017 03:31 PM EDT
    Martin, Thank you for your quick reply. My spray-foam contractor recommended 2 layers of 2" closed cell applied against the sheetrock, waiting for those to cure, then applying a 3rd layer of ...

    It's great to capture these exciting sports moments with a head-mounted camera. My heart was in my throat as I watched your daredevil descent.
  • Josh Dudeck | May 24,2017 03:25 PM EDT
    Martin: Ask my wife... she'll regale you for hours on my lack of brevity. Roof Slope = somewhere between 4/12 and 5/12. I'll climb up and get an exact figure if it is helpful. Thank you.

    "Since 2010, however, they sure have had a lot of mild winters in Aspen. That's great for heating bills, not so great for skiing." Skiing conditions aren't about HDD- it's all about the ...
