Frequently Asked Questions
Q. Why is this product called Fomentek®?
A. The name Fomentek is derived from a combination of two words: Fomentation and Technology:
Fomentation is the use of heat to promote healing or relieve pain. A heating pad is a fomentation device.
Technology is the application of tools or methods.
We shortened technology to TEK, thus our registered trademark name Fomentek®.
Q. How can I tell if the water I put into the Fomentek® bag is the correct temperature?
A. Run the tap water to a temperature that is comfortably warm (110°-113° F) to touch before filling the Fomentek bag . Just as when we adjust bath water, we can sense if the temperature is painfully hot. To be more precise (and train your hands to recognize the temperatures) we offer a pocket clip thermometer.
Q. I have always heard that moist heat is the most often recommended. Does the Fomentek® bag provide moist heat?
A. Yes. The Fomentek bag provides moist heat when it is placed directly against the skin. The body’s own moisture enables the Fomentek bag to transfer heat. (See UNDERSTANDING THERAPEUTIC HEAT)
Q. How long will the Fomentek® bag stay warm?
A. The Large Fomentek bag will stay therapeutically warm for up to 2 hours. This time interval is dependent on the volume of water, temperature and whether the warm bag is in contact with a cold solid object. For example, a warm Fomentek bag laying on a cold granite counter-top will become cold in a few minutes whereas a warm bag surrounded by bedding or a padded massage table will stay warm for well over an hour.
Q. I weigh a lot. Is the Fomentek® bag strong enough to support my weight?
A. Fomentek bags are made of a double layer of modern engineered extruded polymer, which is as soft as flesh, yet strong enough to support up to 600 lbs.
Q. Is the Fomentek® bag guaranteed?
A. Yes. Your Fomentek bag carries a 90 day factory replacement warranty against leaks due to defects in materials or workmanship. Additionally, Fomentek bags carry a 30 day money-back (shipping excluded) satisfaction guarantee.
Q. How does the Fomentek® bag differ from my red rubber hot water bottle?
A. It is imperative that the Fomentek Bag user understand the differences between this product and the traditional (old time) red rubber hot water bottle.
The red rubber hot water bottle is typically filled with very hot water, often from a boiling kettle, and then capped and wrapped in a dry towel before being placed against the body.
The Fomentek Bag, however, comes into direct contact with the skin and that means that the temperature of the filled Fomentek Bag is the exact same temperature the body will experience.
The Fomentek Bag is used directly against the skin at much lower temperatures.
Fomentek Bags should never be used with scalding water, only comfortably warm water no hotter than 113.7ºF (45.4ºC.)
Q. Can I just use a microwave to heat the Fomentek® bag?
A. No. The Fomentek Bag is designed to be re-filled with hot water before each use.
Here is why: When our material reaches 188ºF it begins to lose structural integrity. A microwave oven heats unevenly. Areas of the bag will achieve temperatures as high as 212ºF thus weakening the material.
Q. Can I use ointments or oils with a Fomentek® bag without damaging it? I use ointments and essential oils on my joints for arthritis pain.
A. Yes. Fomentek bags are not harmed or weakened by any oil, liniment, or ointment. This engineered polymer stands up to all solvents, acids or chemicals in any concentration. Even acetone-based fingernail polish remover won’t hurt the Fomentek bag.
However, ALWAYS read the directions on any ointment before applying ANY SOURCE OF HEAT as there are ointments containing a heat-inducing chemical such as Capsaicin that should NEVER be used with any thermal heat because it can result in chemical burns to the skin.
Q. How do I clean the Fomentek® bag?
A. The outside can be cleaned with any detergent. The inside of the Fomentek Bag does not require cleaning, however, if it is stored in a lighted place, algae can develop inside. If this happens, put an ounce of chlorine bleach and a little water into the Fomentek Bag then rinse well.
Q. I am diabetic. Can I still use a warm Fomentek® bag ?
A. Diabetes Mellitus is a serious vascular disease. Consult your treating physician before using a Fomentek Bag or any other heat modality on your extremities.
Q. How long have you been in business?
A. Since 1986.
Do you mention how wonderful FOMENTEK™ Bag s are to travel with? They pack so easily and relieve aches from long hours of driving or flying and being on the go, and sleeping in awful hotel beds. My clients rave about having FOMENTEK™ Bag s with them on vacation.Julie H.
I purchased my FOMENTEK™ Bag from my physical therapist. I had surgeries and the use of your product has saved me. I cannot sleep or exercise without it.Rosemary G.
I really can’t imagine getting by without my Fomentek – it goes on every trip and I keep a spare at our daughter’s home. I’m addicted. I use mine almost every night even in this heat, as it’s the only thing that helps my tingly feet and aching legs.Patricia Beede
