This sounds relevant to my interests. How big/strong heat dish did you use? And for how long at a time?
It’s 1000W but usually used it at 50%
I used it 30-60 min a day for about a week to clear all of my eczema, but I could feel a huge difference after one or two days.
It’s not the optimum things (not designed for FIR) but it did the job nicely and was available.
