I am setting up a boiler/water tank to be used with my self serve and IBA. What functions are suggested to use heated water? I was planning on using it on my pre-soak functions to start with. What is the desired warm/hot water temp?
For SS you only need to heat the water on HP soap, but unless your wax is low pressure or you have two separate gravity tanks it's common for the wax to also be hot. The presoak on your auto should be the only thing you'd need hot, unless you're applying a wax or CCC/CCP that recommends or specifies hot water.
