Yes, you want it to circulate as fast as possible. That's why Mid MN suggested blocking the radiator with cardboard to keep it hot, and the thermostat open and circulating full flow. or remove the thermostat. Dishwasher detergent is already low foam, dawn could work if the system is full so no air? but why bother?
