How to Heat a Wheat Pack Safely

A wheat pack should feel comfortably warm, never hot. Wheat holds heat well and can keep warming after it leaves the microwave, so short, checked bursts are the safest approach.

Heating steps (800–1000 W microwave)

  1. Use a clean microwave rated 800–1000 W. Microwave heating only.
  2. Lay the wheat pack flat in the centre of the microwave.
  3. Start with 30 seconds, then remove and check the temperature.
  4. Continue in 15-second bursts, checking each time, until comfortably warm — not hot.
  5. Never overheat. Allow the pack to cool completely before reheating.

Never

  • Do not heat in an oven, under a grill, on a stovetop or with an electric blanket.
  • Do not heat when wet or damp. The pack must be completely dry.
  • Do not add oils or fragrances.
  • Do not microwave directly from frozen.
  • Stop immediately if you notice a burning, scorching or popcorn smell.

While using your wheat pack

  • Use through clothing or a suitable cover — not directly on bare skin.
  • Do not use under bedding or while sleeping.
  • Use on any one area for a maximum of five minutes at a time, then remove, check skin and pack temperature, and allow a brief break.
  • An adult should heat the pack and supervise children during use.
  • Only for people who can sense temperature and remove the pack themselves.

Why short bursts matter

Microwaves heat unevenly, and wheat is a natural grain. Overheating dries the grain, can scorch fabric and, in the worst case, can cause the filling to ignite. Starting at 30 seconds and adding 15-second bursts lets you stop well before that point.

Always allow a pack to cool completely before you heat it again. Reheating a pack that is still warm is a common cause of overheating.
