    In the beginning of the thread there was a question about circulators pumping through each-other. That does work. I'm pumping through a Taco 007 and doesn't seem to effect things. There was a comment about the close proximity of the 2 circulators,. That I don't know about. Someone way back had called Taco and talked to a rep and they said no harm would come and there would be very little restriction.
    Nice soldering....

    went to get a roll of 12 -2 wire yesterday and seen the price went up about $6.00 a roll. Wonder if pipe is soon to follow ? Seems someone posted last fall that the price was going to go way down. Pat mabey ?

    From the number of copper thefts lately, I'd say the price is back up.

    See pages 16 and 17 (depending on boiler output) of this document: http://www.woodboilers.com/admin/uploads/public/WoodBoilerPlumbingSchematic1110Web.pdf

    also read Appending F to see how all the components work together. Let me know if you have any questions.

    Found some 1" type K coils on Craigslist yesterday, and drove to get them last night.
    I picked up all that I should need to charge my storage tank 400' I got it for about half the shelf price woohoo. Menards price is $5.21 out the door right now, this was $2.60, much more tollerable for this important part of the system. This savings will pay for my chimney, and most my underground Thermopex.
    The stuff is a little corroded on the outside (green dust oxide) but largely it's great. Still in original boxes but the boxes were ripped opened so the copper was exposed here and there.
    I'm going to shine it up with some Con-Coil (coil cleaner used in the HVAC industry)
    Planning on going with the SSTS coil arrangement, two coils about 180' each or I might just use the full 200' for each one. 1 1/8"OD (1"ID) has about 30% more surface area over 7/8OD (3/4"ID) per my primitive calculations.

    The guy said he might have some more rolls if anyone is interested. I told him I wished he had told me before driving out, I would have bought it all knowing how valuable this is right now. I think he could have scrapped it for more than he sold it to me for.
    He said they are out of the box, in a little rougher condition, but that should just be surface corrosion. This is 1 1/8 OD 1" ID, Let me know if anyone is interested.
