Thermophore Digital Moist Heat Pad Model 655 — Large 14" x 27" Electric Heating Pad with Deep Moist Heat, Up to 170°
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 session timer up to 60 minutes. That's 5 degrees hotter and more than double the session time of any other Thermophore. At 170°F it reaches temperatures that no other Thermophore — and no generic pad — can match. 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, the MaxHEAT 155 delivers excellent performance at less than half the price.
Why You'd Choose the Digital 655
- Reaches 170°F — 5 degrees hotter than the MaxHEAT and Liberty models and far hotter than generic 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. Shows current temp and remaining session time. Full temp 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 temps for longer comfort sessions or higher temps 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.
- Moist heat therapy helps relieve arthritis, back pain, muscle spasms, fibromyalgia, and sports injuries by increasing blood flow and relaxing muscles — without NSAIDs or opioids.
- Qualifies for HSA and FSA purchases. Also approved for Medicare reimbursement when prescribed for arthritis pain management.

Frequently Asked Questions
How does the digital controller work?
Select a precise temperature between 115 and 170°F and set a timer up to 60 minutes. The display shows your chosen temperature and remaining time. Reaches full temperature in under 10 minutes — far more control than 3-setting or press-and-hold models.
What is the difference between the Digital 655 and the MaxHEAT 155?
The Digital 655 reaches 170°F vs 165°F on the MaxHEAT 155, has exact digital temp selection vs Low/Med/High, adjustable 60-min timer vs fixed 25-min shutoff, and is the heaviest pad in the lineup. Both are 14" × 27" with automatic moist heat and washable fleece covers.
What temperature range does the Digital 655 offer?
115°F to 170°F. Thermophore recommends 115–140°F for comfort and relaxation, and 140–170°F for therapeutic moist heat. Most generic drugstore pads max out at 120–140°F.
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. No water, spray bottles, or damp towels needed. The cover produces moist heat for 20–30 minutes per session.
Why can the Digital 655 run up to 60 minutes instead of 25?
The digital controller gives you precise temperature control so you can choose a lower, more comfortable temperature for longer sessions. Other Thermophore models have a fixed 25-minute shutoff because they run at fixed high heat settings. The Digital 655 puts duration and intensity in your hands.
Is it HSA or FSA eligible?
Yes. HSA and FSA eligible. Also approved for Medicare reimbursement when prescribed for arthritis pain management.
Can I lay on this heating pad?
No. Place it on top of the body area only. Laying on a heating pad traps heat against the skin and increases the risk of burns. The weighted design keeps the pad in place without laying on it.

What is the difference between the Digital 655 and the MaxHEAT 155?
The Digital 655 reaches 170°F vs 165°F, has exact digital temp selection vs Low/Med/High, adjustable 60-min timer vs fixed 25-min shutoff, and is the heaviest pad in the lineup. Both are 14" × 27" with automatic moist heat, washable fleece covers, and 10-foot cords.
