Since my last Email I have some new info. I talked with Meziere's tech department. This is my new plan

1. Put in the thermostat, drill 2 3/16 holes in the thermostat to allow bypass.

2. Meziere told me that the pump should run all the time and not use a thermostatic temp control. As I had suspected having no water flow in the block is a big NO NO. Hot spots will occur because of the location and charactistics of a thermostat sensor.
