High flow pump doesn't have anything to do with requiring a low temp stat.

You should put in a high flow robertshaw stat. It has a much larger cross section when open.

Or, if it's really high flow (and you really want to defeat the entire point of a stat, then use a drilled stat).

When the tstat is shut the pump can either force it open at high rpms from pressure, or it can run through the bypass opening.

I also recall my heater lines having a small bypass before the valve if I'm not mistaken.
