Morning Ed, I haven't done any green coffee hoarding yet but am hoping the supplies don't end up like the toilet paper isles!

TC4+ Arduino coffee roaster shield (TC4-compatible)
renatoa
As I see engraved on the PCB, you have there a 16 Amps triac, so heatsink is the real limit.
Even current paths on the PCB aren't a real issue, if you double the PCB tracks with some AWG18 wire.
If the traces are 3 mm width, they are good for 12 Amps. They will heat up though, but at the limits of skin touch, 50-60C.
