Web2 days ago · Heat integration Historically, the chemical industry has wasted large amounts of residual energy in the form of “off heat”—heat that is actively cooled down for disposal. This was primarily driven by the low cost of steam generation and the lack of technologies, such as heat pumps, to recycle low-energy residual heat. buy freezer thermometerWebHeating mantle on a lab jack is usually the way to go. Depends upon what you are distilling. For water, a bunsen burner is fine. Otherwise, I prefer a heating mantle: it allows for better heat control, and less chance of catching things on fire.
