About the Thermophore Digital 655

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 model.

The same automatic moist heat from the fleece cover, the same large 14" × 27" coverage, the same 10-foot cord — but with total temperature and session control. 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.

⚠ Important Safety Information

⚠ Do not lay on this or any heating pad — place it on top of the treatment area only ⚠ This pad reaches high temperatures — keep out of reach of children ⚠ Avoid use on fresh injuries, swelling, or open wounds — use cold therapy for the first 48–72 hours after injury, then switch to heat ⚠ The digital timer provides automatic shutoff at your chosen duration 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 session 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 temperature selection vs Low/Med/High, and an adjustable 60-minute timer vs a fixed 25-minute shutoff. It is also the heaviest pad in the lineup. Both are 14" × 27" with automatic moist heat and washable fleece covers.

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. Set aside between sessions to reabsorb ambient humidity.

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 use fixed high-heat settings, which is why they have a fixed 25-minute shutoff. The Digital 655 puts both duration and intensity in your hands.

What temperature should I use?

Thermophore recommends 115–140°F for comfort, relaxation, and general muscle relief. Use 140–170°F for therapeutic moist heat targeting arthritis, deep muscle spasms, fibromyalgia, and chronic pain. Most generic drugstore pads max out at 120–140°F.

Can I lay on this heating pad?

No. Place the pad 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 pad design keeps it in place without laying on it.
