as you know I have had much trouble with colorfastness with idye poly red dyes as I become bolder with the color. I realize red is a high energy color and requires higher temps than possible without pressure. 
How about using an Instapot/Hot pot?
thanks.

Yes, pressure works to get the water hotter.  the color is prettier under pressure too.  Less bricky and more vibrant

I haven't done this personally.  I think getting the color even may be difficult since you can't stir.  This is how they make wigs with polyester dye and this is how they use these poly dyes industrially.
