Haven't read all the posts and just joining now but I see some problems:
piping is small and will provoke a big pressure drop
Piping is flexible and removing air out of your system will therefore be difficult. As long as there's air in the system, you will have no proper flow.
Pump seems too small for 4.000 BTU
The fan will bring in additional heat in the house.
