As some of you already know, I have a deposit on a P and M BL 2840. Won't be here until July, but I guess it's never too early to start with the install. I currently have a forced air wood and oil furnace, 2 seperate units. I'll be putting a water to air hx in the plenum and a water to water hx for my domestic. I also want to run a baseboard heater to my upstairs bathroom, so I wasn't exactly sure how to go about it the correct way. I decided to get in contact with slimjim and was I ever glad I did. I definitely would have run into major issues trying to do this all on my own. What he suggested I do was have my owb run come into a 50 plate hx and then setup a primary secondary loop for the in side install. This way I shouldn't have to worry about ghost flow especially with the baseboard upstairs.
I have most of the parts for the manifold and plan on starting to piece if together very soon. I'll post some pics as it comes along.
For anyone interested, here is a pic of the manifold that slimjim uses. I was a little confused at first as to how it works, but now totally understand it's purpose. It would be best to direct questions to him on how it all works

What does the flaming decaldo?

There is a unit heater there dumping heat from the 250 on my show trailer, the deco is to attract attention to it. The manifold is brought to the shows so that people can take pictures and use them to build their own, it's compact and very functional, in fact it's in my shop right now hooked up to my chip boiler supplying the heat for home and shop. Thanks sceptre74, I've been wanting to get that posted for a long time now.

No problem. I really appreciate all your help so far. It's the least I could do

Where is a manifold of such design actually installed?    In the house or within the plumbing by the water jacket on the OWB itself? 

Any chance we could get a little explanation as to "what is what" and "this does this, and this does that" with respect to the assembled manifold?

Cheers!

The manifold is setup in the basement. The water from the owb enters on the right side in this particular setup. The aquastat is hooked up on the hot side and then wired to the indoor boiler/furnace. Not sure which circuit it goes to. It cuts the power to it as long as the water temperature is above 160. If the owb water falls below 160, power is restored to the boiler/furnace until the water temperature starts to increase or set temp on the thermostat is reached.
The left side is used for whatever your indoor setup is or will be. Hope I didn't confuse anyone as much as I was when I first saw this. Lol

Pre built manifolds make installs and controls very simple and quick. Good quality control too

GREAT job explaining that Sceptre74, thank you.

[Sloppy_Snood]

Thank you for the picture (slimjim too) and explanation sceptre! 

[sceptre74]

No problem. Hopefully it helps someone in the future.

I saw this set up at Slim's this weekend and have a few questions.
          -OWB on right side(this set up)
          -House side on left
          -Both pumps on supply sides to OWB and house
          -Water flows through plate exchanger in opposite direction(think Slim mentioned this)
          -Water fill for OWB is on the return side of exchanger
These are pretty basic questions as I am still trying to grasp the whole concept.

[sceptre74]

No worries. I'm still asking questions about this and lots of other stuff.
Yes,yes,yes,yes and yes. My finished install will be a little different, but basically the same. I'll try to post up the pic slim drew for me

Here it is

You should try to locate your expansion tank on the intake side of the circulator, not the output side, perhaps removing it from the air separator.

The 26-99 is a plenty hefty circulator, are you going to manage speed control?

Yes, going to leave it on low and see how that works. Might end up using the two spade loops in the near future so might as well have the pump big enough from the get go.
What's the reason for the tank on the intake side?
