Chacham's Journal: Question: Which immersion heater? 6

Journal by Chacham

I want to boil water in my stainless steel sink. Boiling water can be poured in, but it must still be boiling while in the sink.

I've told an immersion heater does this. I have no idea what to buy though. I figure something that plugs into an outlet and can handle my single (not double/split) sink.

Any ideas?

Question: Which immersion heater?

  • ... but since when has that stopped anyone from saying anything on slashdot? ;)

    If it's one of those industrial style standalone sinks, what about setting a fire underneath it? (Is it indoors or outdoors?)

    If it's built into a countertop, then the question is whether the cabinetry will be OK with the sink being 100C... if it's cheap particleboard it'll probably start to come unglued. Is this something you're planning on doing on a regular basis?

    Looking around, most of the "immersion heaters" I see are desig

    • There isn't any way to keep that sink boiling without b0rking the supporting cabinetry, and seeing as how most plumbing nowadays is plastic, proly melt the drains and assorted other bits in the process. And the only cheap get it at the home despot immersion heater is an electric hot water element. Which you would still need to cobjob a mount for plus a plug (and these are 220 VAC!!), plus make sure it doesn't all go into the water.

      I love mad scientist stuff as much as the next guy, but this sounds more like

      • On second thought- I found this page Which suggests a thermoregulator [eatfoo.com] is actually the same equipment as a real Sous Vide Thermal Immersion circulator, only more accurate. Search E-bay, is his suggestion.

        I built these [alfter.us] for homebrewing, but they'd do the job here as well. Water heater elements up to 2 kW are available that'll run on 120V; I use 1.5-kW elements.

          I'm a bit nervous about building my own, but it seems that'd be the cheapest route.

  • What you really want is an immersion circulator:
    http://en.wikipedia.org/wiki/Thermal_immersion_circulator [wikipedia.org], Sous Vide in France [techneusa.com] makes them. They usually have their own sink though.

    A cheap, but slightly dangerous way, to make one on your own would be to use a standard resistive range element, being sure to silicon seal the connection to the thermostat and being sure to waterproof all electrical connections.
