I think Sprucebunny is on the right track. You may need mono flow tees but...  Head has no relationship to height, it is a term for resistance and friction loss.. A car radiator has very small tubes in it and that creates a large friction loss or a lot of head.  The 007 might be to small, but if it is piped wrong then pump size will not solve the problem.  I could not open the picture you posted so I can't see how the piping is installed
Think like a farmer.

I'd add a distribution manifold with two 007 size circulators, one for the garage and one for the house with another larger one feeding the manifold.  I prefer Grundfos over tacos  ;) ;D



 

I don't have a pic showing the main pump.  It's to the right and down.  These circulate water through tubing in the 1st and 2nd floor.  One for each floor.

I've got one pump on the stove that feeds the old part of the house.  It'll be moved into the basement eventually.  I'd rather have the pumps in the building if elevations allow it.

All good advice from everybody that I can see to get the flow issue resolved.

Having all the heat exchangers on one circuit, even with enough flow, has got to be hard on the boiler. As far as firebox condensation.

I tried to post drawing but, it's an xls file and can't be uploaded to the thread.

And by-the-way r.man, Happy Birthday.

I think zoning or a primary/secondary set up would be better

My system has a Taco 007 on the back of the OWB, and another one in the house (both on the primary loop). I was told running 2 pumps would eliminate air problems, and give better pump life. I would suggest putting your exchangers on secondary loops, if you get too many restrictions on your primary loop your pump will have a hard time with it.

I have the same setup with a car radiator in the basement. Get a 3 speed grundfos superbrute pump and you can adjust your flow. It's a better pump and its cheaper. The grundfos is as much as a cartridge for taco.

I installed a taco 009, and everything is working good.

Thanks for all your help.
