@spatialking - I have not used the Isonic machine, but I'm not sure you need "heat" to clean records; in fact, the cavitation action alone will cause the water temperature to rise. I took a quick look on Amazon to see what machine you might have bought and the description, while including heat settings, said that certain models don't include a heater.
Does the device you received have some sort of forced air drying? I assumed it was an ultrasonic bath with a rotisserie or other record spinning mechanism only.
