Hello everyone. I need help with the selection of statistical methods for one experiment. I'm a total newbie to the statistics

So, I need to compare the trend of temperature at two different types of open fireplaces. Wood will be stacked in parallel (fireplace1), and transverse(fireplace2) way. The variables are the temperature measured at 2 different heights and at 3 different distances from a fireplace, measured every 5 minutes during the entire period of combustion.

To determine the average temperatures difference between the two fireplaces, I guess I need to use the t test for independent samples?

I am interested in your suggestions. Can I somehow apply polynomial regression analysis? With the time as an independent variable and the temperature as dependent variable?
