Thermophore Digital Moist Heat Therapy Pad — Large 14" × 27" (Model 655)
Our hottest, heaviest, and most advanced heating pad. Digital controller lets you dial in your exact temperature from 115°F to 170°F and set a timer up to 60 minutes. The heaviest pad in the Thermophore lineup for maximum body-contouring contact. Automatic moist heat without water. Full temperature in under 10 minutes. Drug-free pain relief trusted by doctors since 1931.
This is a very good heating pad. It feels like a high quality device. The digital controller makes it easy to adjust. This pad can get very hot so don't let little kids play with this.
Our Take: The Digital 655 is the flagship Thermophore — the hottest, heaviest, and most precise pad in the lineup. The digital controller lets you set your exact temperature anywhere from 115°F to 170°F and choose a therapy session timer up to 60 minutes. That's 5 degrees hotter and more than double the session time of any other Thermophore. It's also the heaviest pad in the lineup, so it contours to your body with even more surface contact than the already-weighted MaxHEAT and Liberty models. At 170°F it reaches temperatures that no other Thermophore — and no generic pad — can touch. The same automatic moist heat from the fleece cover, the same 14" × 27" large size, the same 10-foot cord. Thermophore recommends 115–140°F for comfort and relaxation, and 140–170°F for therapeutic moist heat. If you want maximum control and maximum heat, this is the one. If you don't need digital precision and want to save, the MaxHEAT 155 delivers excellent performance with a 3-setting switch at less than half the price.
Why You'd Choose the Digital 655
- The Digital 655 reaches 170°F — 5 degrees hotter than the MaxHEAT 155 and Liberty models and far hotter than generic drugstore pads. When you need the most intense therapeutic moist heat available, this is it.
- Select any temperature from 115°F to 170°F on the digital display. No more guessing between Low, Medium, and High. The controller shows your chosen temperature and remaining session time. Full temperature is reached in under 10 minutes.
- Set therapy sessions up to 60 minutes — more than double the fixed 25-minute shutoff on other Thermophore models. Use lower temperatures for longer comfort sessions or higher temperatures for shorter therapeutic bursts.
- The Digital 655 is the heaviest pad Thermophore makes. More weight means more body-contouring contact, fewer air gaps, and more consistent heat delivery across the entire surface.
- The same large 14" × 27" coverage as the MaxHEAT and Liberty models. Covers the full back from shoulders to lower back, wraps around a hip or thigh, or drapes across both shoulders.
- The fleece cover absorbs humidity from the air and the pad's intense heat converts it to therapeutic steam. Moist heat penetrates deeper than dry heat into muscles and joints without adding water.
- Moist heat therapy is a proven drug-free method to relieve pain from arthritis, back pain, muscle spasms, fibromyalgia, and sports injuries. No NSAIDs, no opioids — just therapeutic heat at your chosen temperature.
- The Digital 655 qualifies for Health Savings Account and Flexible Spending Account purchases. Also approved for Medicare and insurance reimbursement when prescribed for arthritis pain management.

Frequently Asked Questions
How does the digital controller work on the Model 655?
The Digital 655 features a digital controller that lets you select a precise temperature between 115 and 170 degrees Fahrenheit and set a timer for up to 60 minutes of continuous heat. The controller displays your chosen temperature and remaining time. The pad reaches full temperature in under 10 minutes. This gives you far more control than the 3-setting or press-and-hold switches on other Thermophore models.
What is the difference between the Digital 655 and the MaxHEAT 155?
The Digital 655 is the most advanced Thermophore. It reaches up to 170 degrees Fahrenheit versus 165 on the MaxHEAT 155. It has a digital controller with precise temperature selection from 115 to 170 degrees instead of just Low, Medium, and High settings. The timer is adjustable up to 60 minutes instead of a fixed 25-minute shutoff. The Digital 655 is also the heaviest pad in the lineup. Both are 14 by 27 inches with automatic moist heat, washable fleece covers, and 10-foot cords.
What temperature range does the Digital 655 offer?
The Digital 655 offers a temperature range from 115 to 170 degrees Fahrenheit. Thermophore recommends 115 to 140 degrees for comfort and relaxation, and 140 to 170 degrees for therapeutic moist heat. You select your exact temperature on the digital controller. For comparison, most generic drugstore pads max out at 120 to 140 degrees Fahrenheit.
How does the Thermophore produce moist heat without adding water?
The fleece cover absorbs moisture from the humidity in the surrounding air. When the pad heats up, it activates that moisture into therapeutic steam that penetrates deeper into muscles and joints than dry heat alone. No water, spray bottles, or damp towels are needed. The cover produces moist heat for 20 to 30 minutes, after which it begins to dry out and the pad should be set aside to regain moisture from the air.
Why can the Digital 655 run for up to 60 minutes instead of 25?
The Digital 655 has an adjustable timer that lets you set therapy sessions up to 60 minutes. The digital controller gives you precise temperature control, so you can choose a lower, more comfortable temperature for longer sessions or a higher therapeutic temperature for shorter sessions. Other Thermophore models have a fixed 25-minute shutoff because they run at fixed high heat settings. The Digital 655 puts the duration and intensity decision in your hands.
Is the Thermophore Digital 655 HSA or FSA eligible?
Yes. The Thermophore Digital Model 655 is HSA and FSA eligible. It is also approved for Medicare and insurance reimbursement when prescribed for arthritis pain management. Check with your insurance company to verify reimbursement, which can vary by coverage.
Can I lay on this heating pad?
No. It is not recommended to lay on this or any heating pad. The pad is designed to be placed on top of the body area being treated. Laying on a heating pad can trap heat against the skin and increase the risk of burns. The weighted design ensures the pad stays in place and maintains full body contact without the need to lay on it.
