I circulate through the heaters until the VO is 100F at the CF inlet. In the summer this is within minutes of startup.

I do as Sunwizard does, but there is no reason you couldn't start running with cold oil through the CF as long as the pressure is held within CF operating tolerances, either using a bypass valve or a pressure regulator. I've done it both ways, depending on whether or not I wanted to babysit the oil as it warmed up. In the beginning, I didn't have the electrical supply to run the 2 heaters and a pump.

If I've got 2 heating elements running simultaneously at the start, as I do now, I'll let them heat the oil in the heater pipe for a min before turning on the pump. By then, the oil is starting at about 100+ F at the CF start and with 2 heaters and a pump pushing at 1 gal/min, the oil only gets hotter and hotter at a fairly fast rate.

If your pressure regulator immediately follows the pump, you won't heat oil that gets bypassed by the pressure regulator, so your CF oil would heat up even more quickly at the gitgo.

Yes its always safer to have a thermostat.
