Plumbing / Re: Adding a branch to heat a workshop

OK, thank you for your time and advice.  Just to make sure I understand this correctly ... I am running ~50 feet from the OWB into my Dad's basement through 1 1/4" Central Boiler thermopex.  I will go into a 1 1/4" x 1" x 1" (I guess) tee just inside the basement wall and run one side of the tee through the existing TV and to my Dad's boiler about 10 feet away (ultimately to a plate exchanger that I suppose I would have heat up the water being returned into the bottom of my dad's boiler) and the other side of the tee will go across my dad's basement and over to the workshop (~100 feet) where it will go into it's own TV before going into some type of heat exchanger over there.  I should not rely on the circulator pump at the boiler to drive both of the loops, but it will continue to drive the side of the tee that goes to my Dad's furnace?  I would put another pump (running continuously) on the other side of the tee in the loop that is going over to the shop.  Disregarding the Taco 009 that I already have, could you tell me what brand/size pump you would put at the OWB (or would you move it into the basement away from the OWB?) and what brand/size pump you would put on the loop going over to the workshop (and where would you locate that pump?)?  Thanks again!

Sorry, the two circulator pumps at the outside boiler that feed my house and my dad's are actually Taco 009-BF5 pumps.  The distance from the outside wood boiler to my dad's basement is just under 50 feet.  It is then about another 100 feet over to the workshop (25 feet across my dad's basement and then another 80 feet underground).  As far as the heat load at the new building, I have not attempted to calculate that, but it is basically a small old deserted one story house (with a basement) that I finally bought and am putting to use.  It is approximately 24 feet by 48 feet.  I have basically gutted the house and am using it for storage and a growing workshop.  I am working on improving the envelope (tore off old faded siding and replaced with Tyvek and board-and-batton, adding insulation on the inside.  I don't envision ever wanting/needing it to be terribly warm in there, but keeping it above freezing with the ability to get it up to 50 or 60 when I want would be great.  Oh, and the underground thermopex is from Central Boiler.

I have a CB E-Classic 3200 that is heating my house and my Dad's house with no issues.  It was installed professionally a few years ago and there are two Taco 007 circulator pumps out at the boiler pushing water to both houses through 1 1/4" underground, insulated PEX that then ties into both indoor boilers.  I am now going to extend an underground 1" insulated PEX line that will go out the other side of my Dad's basement and run about 80 feet to another building that I would like to supply some heat to.  My question(s) are related to how to plumb that line from where the 1 1/4" pex currently comes into my dad's basement and enters his furnace.  I plan to take a branch off the 1 1/4" PEX at some point after the thermostatic valve that is just inside my dad's basement wall (which returns the water back to the OWB if it drops below a certain temperature (150 maybe?).

1) Do I just split off the 1 1/4" with a tee to run the 1" out to the workshop?

2) Do I bring the 1 1/4" into a header (or manifold) in my dad's basement and then run it to both his furnace and the line that goes out and to the workshop?

3) Ultimately, I think i would feel better about running into a plate heat exchanger for my Dad's furnace instead of going straight into his furnace and having to de-pressurize his system every winter.  If I did that, should I first go to the HX for his furnace and then go to the workshop (running them in series), or should I still split the line having it go to both the HX for his furnace and the workshop (in parallel)?

4) Depending on which option is chosen, would I need another circulator pump to move the water through the workshop and back?

Thanks in advance for any advice.
