Ed, The first thing that you need is a digital multimeter set to read the current in your brew cell. The initial current is probably the best indicator of the quality of yourDW.
There is no need to heat the DW. I have been evaluating many protocols to make CS in the last 4 years and find no need to heat the water. Obviouly the 45 minute brew time is very excessive for heated water. Try a run with room temp. water with a meter in the circuit. With very good DW the current will be in the range of 0.2 to 0.4 ma. If it is in the 2.0 to 5.0 ma range the water is junk. Stop the brew when the current is about 3 to 4 ma.These numbers are for 14 to 16 ounces of DW.
