Is it electric or gas? Yes if it is electric. The burners are new and tend to burn hotter at first. The wattage of your burners may be higher than your old stove.
Gas.... The holes can get clogged over time with burnt food or grease and thereby will burn cooler as time passes. The BTUs may be higher with your new stove.
Also, you are going through a learning phase with your new stove. Happy Cooking. Do let us know about all those new dishes you are going to be preparing.
