Yes, I see mixing with injection section. Haven't done my homework on that section yet.
About the picture above.
Should the 3way valve and circulator be placed near the boiler, or better to place it in another building close to radiant heating floor?

The Distance between a garage where boiler is installed and main living house is about 300'

Pipes have no choice going the distance one way or another, but the control sensors would be best not run the 300' distance.

Yes, I thought about sensors. I guess I will use low resistance thick wire and recalibrate sensors.
About pipes.
If valve and circulator placed near boiler then the only boiler and near pipes are kept hot, outside underground pipes will be heated only when valve opens. So, there going to be some time delay.
If valves and circulator placed in another bldn, then, exterior underground pipes will be kept hot all the time. I think second scenario suits me better

Either works there are just bigger penalties with some...

Update: I took my plumbing schematic to a radiant heating supply store nearby. The manager, who installs systems like these professionally, looked at it, asked about the boiler type, and said that I had a perfect setup for a variable speed injection pump. He drew a quick picture showing where it should go, how it should operate, and ways to hook up my dump zone (and in turn helpcto heat my garage). He is compiling a list of all of the parts I will need for the full install, and will have them all ready for me once I am ready to start. Super helpful! I am glad I made that short trip!
