But How? Our system runs on a natural flow called thermosyphon — no pump, no wires. As fire heats the water inside the coil, hot water rises out the top and flows back into the tub.At the same time, cold water from the bottom of the tub gets pulled into the coil to be heated. This creates a steady, silent cycle powered only by fire and gravity. Quick and Easy Installation Installation takes about 20 minutes. It's a quick and easy DIY project; the only tool needed is a power drill. Just drill two holes, mount the wall ports, and hook up the hoses. Now you're ready to soak. BBQ Grill Functionality Place a grill, hot plate, or large wok over the coil to enjoy flame grilled food while the tub heats up.
