.... The water thing I haven't got totally nailed yet but getting there. I'm just finding it a bit of a pain in the arse getting the temperature right quickly. The water comes out of my cold tap about 15c at the moment although come summer that'll be coming out much warmer, as Walter was telling me the other week.
I'm thinking of getting a water tank (like a home brew fermentation tank with a tap) and leaving my fish tank heater dunked in it so I have water "on tap" ready to go. I'm still working on the basis of a bit of cold, bit of hot, bit of cold to get it up to 20c. It's works but I want to spend more time developing and less time getting my water right!...
Developer temperature control is a non-event for me in terms of anxiety about methods or results.
About 6 years ago I started the replenished Xtol batch that still works perfectly today after many square metres of film have gone through it. All films go into rep-Xtol, just at different developing times that have been calibrated for each by experiment. Replenished Xtol delivers a predictable activity versus temperature performance. For example Fomapan 400 comes out the same at 13 Celcius @ 23 minutes as it does at 34 Celcius @ 2minutes 45 seconds! In-between temperatures have known in-between times all determined by some one-off conscientious experimenting. Now I just measure the temperature and instantly know the right developing time...except when I'm in a hurry or have a big batch of film to do. Then the dev/stop/fix trays get floated in bigger trays of hot water, the temperature is measured, and processing proceeds apace. My last big session was 32 Celcius @ 3minutes 20 seconds and several dozen nice 4x5 negs (via 4 place slosher) came out as expected.
