    There was a post several years ago here that described small animal heating pads that could be set to a desired temperature. The example shown was for baby piglets. It might be of interest here.

    I prefer to do things at room temp.

    Regarding C-41, current Bleach III consists of 2 parts. Versions from 3 or 4 years ago used 1 part. Replenisher for bleach, fix and stabilizer are not needed.

    My experience with electric hot-plates, 'food warmers' etc., is that the thermostatic controls are less than satisifactory - large temperature swings, and quite often 'load dependant' (meaning sensitive to the amount of water etc., being kept warm). If you are a DIY'er, one can cobble together a temperature controller from a triac and temp-sensor (lm35).

    I use a Corning 5x7" ceramic hot plate/stirrer with integral control probe. I set the temperature that I want and it stays there +/- 1 degree or less. I do use it to keep my C41 stuff up to temp without wasting water.

    Those are nice! Little pricey though.

    Yes, but essential for making emulsions.

    And, that was your question in the OP..... So, I pointed out that it was possible.

    It is pretty hard to get things to 50 - 80 C using hot water. It takes a lot of hot water. If you heat it, you use a hot plate to keep the bath up there.

    I have tried a lot of alternatives for making emulsions well and the controlled hot plate does well.

    An uncontrolled plate is very nice, as long as you are willing to stand there and fiddle with the knob. That works just fine and is less expensive but more labor intensive.

    So, in the absence of any alternative, I feel that I can stand by what I say.

    Yes it was and I do appreciate the info, I did not know those existed.

    I'm not making emulsions yet and the water bath/microwave system is giving me good results so I may join the "fiddle the knob" crowd for now so I can put more money into film, paper, and chemicals.

    The problem with those plates would be the residual heat kept up in the plate. If you turn it on 10 and then shut it off when the bath reaches temperature, the bath temperature will continue to rise for some time after.
