As soon as the heater gets the signal to turn on the fan starts and the burners fire up. However it takes about 30sec to 1min for the heater to warm up thus delivering warm air not cold air.
New units like the brivis ME and HE series actually start the burners first, wait until the temperature of the air gets to 50celcius and THEN start the fan, meaning no cold air blowing into the home - only warm air.
