I put this piston in the sink yesterday, the temperature of the sink was 18 C. I set the sink to 60 C, put the piston in, and started the transducers. The transducers run on a timer, and run for up to 30 minutes.

I left it there for about 3 hours, I'm not sure how hot it got, but when I took the following pictures, the heaters had turned off (I guess they're on a timer... bummer) but with minimal effort, I would call this a huge win.

Now, this is actually the second sink I have owned, the first, the heaters didn't time out, which was desirable to me, because I don't think the sink even gets up to temperature by the time they turn off. my other sink, which stopped working after it got rained on, did not have timers on the heater, only the transducer.
here was the first sink I bought, without the timers.

in both sinks, I have used this solution with excellent results.
