Hotties are designed to fail-safe in the event of overheating. This means, if overheated for a long period of time, the pouch is designed to split. This may create a “bang” noise, but is an important safety feature that prevents the build up of dangerous pressures and hot spots. Hottie will not explode or burst violently if overheated. As Hottie contains no gels or seeds there is no danger of it catching fire or causing burns. ▼What is inside my Hottie? Hottie is not a hot water bottle. Hot water bottles are known to cause burns. This is because of the fiddly design requiring filling with boiling water and also due to rubber bursting or splitting, spilling boiling water onto the user. We urge people to take extra care when re-heating a recently used Hottie as this seems to be when most people accidentally overheat and damage their Hottie. Please see FAQ "How do I re-heat my Hottie?" for further information on re-heating a Hottie. ▼How does it work?

Remove fabric cover if it prevents your Hottie rotating freely in the microwave. Re-heat in 15 second increments, testing temperature each time to avoid damage. Hottie will not explode or burst violently if overheated. As Hottie contains no toxic gels or seeds there is no danger of it catching fire or causing burns.

If you overheat Hottie and it pops, leave in microwave for at least ten minutes before lifting out. How long a Hottie lasts is a function of how carefully it is heated. If always heated correctly there is no reason a Hottie should decline.

The plastic pouch is composed of layers of different plastic types and is classified under Resin Identification Code (RIC) 7, which is the classification for “other plastics”. Ensure your recycling program accepts materials under this classification. We have been making Hotties since 1996 and in all that time we have never learned of a Hottie causing injury or exploding violently. If overheated, Hottie pops and oozes its water content. This is a built in feature designed to keep you safe by preventing Hottie reaching dangerous temperatures and pressures.
