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 have 2 modine heaters in my garage. they are bolth 12' off the floor and its only 20' to the owb. i have had trouble a couple times in the fall when i first start a fire. the water will not circulate. so i put a tee and a valve so that i can hook the garden hose to it. turn it on and after a few mins all is fine

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 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.
