This is my attempt at designing a system for my house and pole barn running off the same OWB.
I have never done anything like this before so if you have any input of where I am going wrong or have an idea on how to make it better please let me know your thoughts.
I have looked at numerous webpages/videos trying to figure this out.
The Idronics catalogs and Coffee with Callefi videos had allot of good info.

My thoughts are to have a Primary/Secondary loop system. With one outdoor reset that controls the water temp for both the garage and basement floor heat in the house. And another outdoor reset for the barn to control both concrete zones.
In the house I would like to heat the following.
2 water to air heat exchangers. Mounted in the existing ductwork. One is on the first floor and the other is on the second.
Domestic hot water with a Flat plat heat exchanger. Anti scald valve on top.
Attached garage concrete floor. 3 - 300 ft loops
Basement concrete floor. 6 - 300 ft loops.
Pole barn has the following.
Unit heater hanging from ceiling
Domestic hot water with a Flat plat heat exchanger. Anti scald valve on top.
Small baseboard radiator heater for small bathroom.
Main zone concrete: 8 - 300 ft loops
Secondary zone 1 - 300 ft loop.
Once I get a system design nailed down I need to figure out where to put all the valves, flanges,
drain ports, etc.....
Does anyone know of a free software that would help with system design and part specification?
Thanks for your time.
