An apparatus for collecting a substance has a fluid source providing pressurized fluid, a heating device, a heat transferring device and a vacuum producing device. The heating device is coupled to the fluid source and is adapted to cause a first pressurized fluid from the fluid source to become heated. The heat transferring device is coupled to the heating device for receiving the heated first pressurized fluid, and is adapted for transferring heat from the first pressurized fluid to a heatable substance. The vacuum producing device has first and second inlet openings, the first inlet opening is fluidly coupled to the fluid source for receiving a second pressurized fluid from the fluid source and the second inlet opening is adapted for receiving the heatable substance. The variation of the apparatus can recycle heated fluid back into the apparatus once used to heat the heatable substance. Another variation of the apparatus can use the hot and cold fluids from the heating device in heat exchangers, respectively, and multiple heating devices can be used in series to further heat or cool the hot and cold fluids.
