The HydroHeater™ is designed to thaw your frozen hydration tube

It is important to do everything you can to prevent the tube from freezing:

  • Blow back – flush the water from the tube by blowing back into the tube until you hear the air reach the bladder with a gurgle.
  • Keep inside jacket – protect the tube from the extreme temperatures be keeping it inside a jacket as close to your body as possible.
  • Run tube from bottom when possible – We have found that a tube routed up from below stays drained better than a tube run over the shoulder.
  • Drink lots – it's good for you to keep hydrated, but it also keeps the tube fresh with the warm water from the bladder.

We also suggest only using water in the system in order to keep the tube clean. Because the heating element is inside the tube, it is more difficult to clean the tube and heating element.

There are many times that in spite of your best efforts the tube freezes anyway. When that does happen, you can turn on the HydroHeater™ and thaw the tube.

Here are the instructions for using the HydroHeater™:

  1. Use EIGHT (8) Lithium batteries only. Energizer Ultimate Lithium batteries are the recommended battery.
  2. Plug the system in at the battery pack.
  3. When your hose freezes, Hold button down, the light will flash rapidly.
  4. When the light stops flashing (6 seconds), release button.
  5. Light will begin flashing slowly (once per 2 seconds) and heater is heating.
  6. Heat will turn off automatically after about 10 minutes. To turn off manually before the 10 minutes have elapsed, hold down button until slow flashing stops.
  7. If the first run of 10 minutes didn't thaw the tube completely, start over at step 2 and run it again as soon as possible.
  8. When the system is no longer needed, UNPLUG the system at the battery pack.

As the battery pack runs down, you will notice that you need to run it several times to fully thaw. This is a sign that it's time to replace the batteries. Our testing indicates that the batteries should be good for 10 to 15 heating cycles. This is dependent on many variables including outside temperatures, and the time between heating cycles. At very cold temperatures even Lithium batteries have a slightly reduced capacity.
