Personally I think that unit would only be of use for colour processing which use higher temperatures and then it wouldn't be of any use for E6 5 bath because it only has 3 bottle holders.

Why do I think that? Because if you use a kitchen washing up bowl it is just as good. You fill the washing up bowl with water at the required processing temperature. The volume of water in the bowl is such that it will take at least 20 minutes for it to change temperature, especially if your room temp is around 20 deg C and your processing temp is 20 deg C.
Then you mix your chemicals into some of those plastic bottles using water from the bowl, put the lid on, and float the bottle in the bowl. So you now have a water bath keeping your chemicals at correct temp.
As for your processing tank, well if your room is at around 20 deg C, then when you pour chemicals into the bath, they will not drop in temp. However, you can measure temp of liquid when you pour out. It may be a deg or even two lower than when it went in depending on ambient temperature. But if that is the same everytime you develop, then it is consistant and that is what is important. So if your ambient room temperature is consistant when doing your film development, then you don't need a heated processing machine for B+W film.
For colour things are a bit different because of the temperature differential between chemicals and room temperature. There will be some temp drop off. But even then, if your bowl of water is at 38 dec C to start with after mixing chems and floating bottles in bowl, then drop off in temp will be minimal and you can stand your tank in the bowl if the bowl water level is correct to allow that. Floating tank in bowl is not a good idea.
So a kitchen washing up bowl will do exactly the same for you and is a lot cheaper.
