Why Thermophore Beats Other Heating Pads

Most heating pads barely get warm, slip out of place, and only treat the surface. The Thermophore Liberty 155 delivers deep, penetrating moist heat that generic pads simply can’t match. With a full-size weighted design, it contours to your body, stays in place, and gets hot fast—without the hassle of adding water.

Three heat settings, a one-touch switch, and a 25-minute safety timer put you in control of professional-grade relief. Assembled in America and backed by over 90 years of trust, this isn’t just a heating pad—it’s the one your pain deserves.

What Is Moist Heat Therapy?

Moist heat therapy uses water vapor to conduct heat deeper into muscles and tissues than dry heat (like a standard heating pad or heat wrap). It’s commonly recommended by physical therapists and pain specialists for more effective, longer-lasting relief.

Benefits of Moist Heat Therapy:

  • Penetrates deeper than dry heat

  • Increases blood flow to promote healing

  • Relaxes stiff joints and muscle spasms

  • Eases chronic pain from arthritis, fibromyalgia, or injury

  • Reactivates natural lubrication in joints and connective tissues

When to Use Moist Heat Therapy

  • After the first 48–72 hours of an injury (once swelling is down)

  • For chronic conditions like arthritis, back pain, or sciatica

  • To relieve muscle tension, soreness, or spasms

  • Before stretching or exercising tight muscles

  • During recovery from sports injuries or overuse

⚠️ Avoid using heat on fresh injuries, swelling, or open wounds—use cold therapy first, then switch to heat once inflammation has decreased. Always consult your doctor or healthcare provider for proper guidance when treating injuries.

Why Does the Thermophore Have a 25-Minute Timer?

The 25-minute auto shut-off is a safety feature designed to:

  • Prevent overheating or burns from extended use

  • Avoid falling asleep with the pad on (a common misuse risk)

  • Follow clinically recommended therapy intervals (15–30 minutes)

Thermophore pads reach higher temperatures than generic brands, so limiting exposure to 25 minutes at a time provides safe, effective relief without risk of skin damage or overheating.

Best heating pad, ever!

I have had a thermophore for many years. My mother in law had one that passed to me. My teenage daughter took it away so I ordered a new one. I really like the new 3 heat settings and auto shutoff. Just keeps getting better!

2nd one purchased

I purchased one in 1998 and have used it extensively. It’s pretty beat up so I ordered another one. The timer on the switch is a nice touch and keeps things safe. This thing gets HOT on the high setting. The moist heat is incredible. If you’re thinking of getting one choose this brand. You won’t be disappointed.

This is my second one.

I love how hot it gets in the washable coverlet.
