# How to calculate thermal load?

basically I am trying to build an oven that we are going to use to cure prepreg carbon fiber. I found a company that can make it but they are requesting the termal load in order to continue.

This is the information I already have: Dimensions of the oven: 23.7in x 59in x 59in (height, width, depth) Desired temperatures: max 284F, min 158F

I have found the formula to calculate this, but honestly, I don't know how to begin:

q = -k A dt/dx
q = heat transfer rate, Btu/hr
k = thermal conductivity, Btu/(hr-ft-F)
A = area normal to heat flow, ft^2
dt/dx = temperature gradient, F/ft
