Why waste hot water...it's going down the drain...unless you use 100% of the elevated tds water for watering plants or whatnot. People talk about how much systems costs when up and running using hot water would just be another energy bleed. I use straight cold in Calgary and happy with the product of my unit.
I threw on a pressure gauge and adjustable valve on the water input keeping it @ 70-75psi and never looked back with any problems.
