    I am looking to build a DIY hot water bath, I was planning on using a small screw plug immersion heater, drilling a hole into a polypropylene tank and using a nut/gasket to seal it.

    Recon it could work?

    It would probably work, but why would you want to do it? Consider:

    1. Make sure its earthed and fed through an RCD.
    2. What's going to turn the electricity off when its reached temperature, or does the heater have a thermostat?
    3. That tray you illustrate doesn't have vertical sides, so the top of the element might poke out of the water unless you're careful.
    4. The melting point of polypropylene is about 160C, but it may get soft at lower temperatures.
    5. How are you going to stop it boiling / evaporating dry?

    Assuming your intention is to set fire to something or electrocute someone it'll probably work okay.

    What's the problem? Isn't the traditional toaster-in-the-bath going to work in your case?

    So the overall consensus seems like 100% guaranteed success.

    I was planning on using a cheap temperature controller and thermo-couple to avoid most of the fires caused, the others I guess will have to be dealt with whenever they occur. Hopefully the plastic lid will stop the water boiling dry, if its not in its molten/fiery state.

    The plan was to build a heated water bath around 50 C for cleaning parts. It'll have some pure water in so I'm limited to using only stainless and polypropylene.

    I could, however I want it a bit more fancy.

    I was going to put glassware in it, that needs to be really clean. The plan was to have two polypropylene containers, one inside the other, so that all the gunk will flow over the top of the inside one and collect in the outside one.

    Could maybe use a stainless container, that might get rid of a lot of the fire potential:

    Hello, I can`t really contribute to this thread apart from agreeing with other Members that this `contraption` exudes DANGER !

    I have found that I cannot post a new thread without getting a Forum Error Message about having too many `Tags` even though there were no Tags within the message.

    I have asked Moderator Lou about this.

    I have replied to this thread just to see IF I can submit a reply even though I cannot submit a new thread.
