Thermophore MaxHEAT Plus Moist Heat Pack (Model 356) Medium (14 x 14)
Thermophore MaxHEAT Plus Moist Heat Pack — Medium 14" × 14" (Model 356)
The medium-size Thermophore with the Moisture-Plus cover — reliable moist heat in any climate. 3 heat settings, weighted construction, up to 165°F, 25-minute auto shutoff. The Moisture-Plus cover lets you add a moist cloth in dry or heavily air-conditioned environments. Sized for a single shoulder, knee, abdomen, or hip. The same Thermophore quality trusted by doctors since 1931.
Hottest electric heat pad on the market. Even the fabric and stitching feels higher quality than anything else I've tried. Very much worth the price!
Our Take: The MaxHEAT Plus 356 is the medium-size Thermophore with the Moisture-Plus cover. Same 14" × 14" size as the MaxHEAT 156, same weighted construction, same 3 heat settings, same 150–165°F range, and same 25-minute auto shutoff. The difference is the cover: the Moisture-Plus cover lets you add a damp cloth inside for supplemental moisture in dry or heavily air-conditioned environments. Standard Thermophore covers rely on ambient humidity and work well in most homes, but the Moisture-Plus cover gives you more control when indoor air is dry. If you do not need the Moisture-Plus cover, the MaxHEAT 156 is the standard-cover option. If you want a USA-assembled medium model, the Liberty 156 is the closest alternative.
Why You'd Choose the MaxHEAT Plus 356
Tip: Tab to a reason. Press Enter or Space to toggle details. Press Escape to close.
- The Moisture-Plus cover produces automatic moist heat from ambient humidity. In dry or heavily air-conditioned environments, add a moist cloth inside the cover for supplemental moisture. The most versatile medium Thermophore cover option.
- Covers a single shoulder, wraps a knee, covers the abdomen, or targets a hip. More manageable than 14" × 27" large models. Good for petite users and travel.
- Reaches 150–165°F — dramatically hotter than many generic drugstore pads that top out around 120–140°F. Designed for deeper therapeutic heat.
- Three temperature levels with a hands-free switch. Start on Low for comfort, step up to Medium for moderate relief, or use High for maximum intensity. Stays on until the 25-minute auto shutoff.
- The weighted construction molds to curves and joints, maintaining full surface contact. Stays in place without you holding it.
- Customers often note the fabric, stitching, and overall build quality compared with lower-cost heating pads. Designed as a durable therapeutic product.
- The 14" × 14" format is easier to position than a large pad and is well suited to more focused relief on one area at a time.
- The MaxHEAT Plus 356 qualifies for HSA and FSA purchases and may be reimbursable through Medicare or insurance when prescribed for arthritis pain management.
Perfect For

Frequently Asked Questions
What is the difference between the MaxHEAT Plus 356 and the MaxHEAT 156?
Both are 14 × 14 inch medium pads with 3 heat settings, 25-minute auto shutoff, and up to 165°F. The key difference is the cover. The MaxHEAT Plus 356 includes the Moisture-Plus cover that lets you add a moist cloth in dry climates for supplemental moisture. The MaxHEAT 156 has the standard fleece cover that relies entirely on ambient humidity. Both use the same hands-free switch.
What is the Moisture-Plus cover?
The Moisture-Plus cover produces automatic moist heat from ambient humidity like all Thermophore covers. In very dry or heavily air-conditioned environments where there is not enough humidity in the air, the Moisture-Plus cover allows you to add a moist cloth for additional moisture. This makes the 356 the most versatile medium Thermophore for any climate.
What is the MaxHEAT Plus 356 designed for?
The MaxHEAT Plus 356 is a medium 14 × 14 inch pad designed for targeted areas like a single shoulder, knee, abdomen, or hip. It is also a good size for petite users and for travel. The Moisture-Plus cover makes it especially versatile for use in any climate or environment.
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. In very dry environments, the Moisture-Plus cover lets you add a moist cloth for supplemental moisture.
What temperature does the MaxHEAT Plus 356 reach?
The MaxHEAT Plus Model 356 reaches between 150 and 165 degrees Fahrenheit. It has three heat settings: Low, Medium, and High. For comparison, most generic drugstore heating pads max out at 120 to 140 degrees Fahrenheit.

Yes. The Thermophore MaxHEAT Plus Model 356 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. The weighted design ensures the pad stays in place and maintains full body contact without the need to lay on it.
