Chattanooga Theratherm® Digital Moist Heating Pad

The Chattanooga Theratherm® Digital Moist Heat Pack is a self-contained electric moist heating pad with adjustable temperature and treatment time, a digital hand controller, automatic shut-off, and a flannel exterior designed to retain moisture.

Unlike a traditional hot pack that must first be heated in a water-filled tank, Theratherm generates heat electrically at the treatment site. Its specially designed flannel material draws moisture from the surrounding air as the pad warms, creating moist heat without requiring a Hydrocollator® heating unit.

Choose from three current Chattanooga configurations:

Current specifications list adjustable moist-heat temperatures from 113°F to 166°F, treatment periods of up to 60 minutes, automatic shut-off, a setting lockout, and a one-year warranty.

The key distinction is control.

Many conventional electric heating pads offer several preset levels, such as Low, Medium, and High. Instead, Theratherm uses a digital controller that allows the user to program and monitor the treatment temperature and time.

That can be useful when the goal is to have a repeatable heating setup rather than estimating a setting from a simple numbered or color-coded control.

The controller also includes a lockout mode, which Chattanooga designed to prevent unintended setting changes during a treatment session.

Digital Control

Theratherm allows the operator to control the following:

How Theratherm Creates Moist Heat

Theratherm uses a different approach than heating pads that require a separate damp sponge or clinical hot packs that are immersed in heated water.

Its flannel cover draws moisture from the surrounding air. As the pad warms, that retained moisture contributes to the moist-heat application.

This gives Theratherm a relatively self-contained workflow:

Plug in → select temperature and treatment time → position according to the instructions → begin treatment.

There is no separate Hydrocollator tank to maintain and no reusable hot pack that needs to be returned to a heating unit between sessions.

1031-B Medium — 14" × 14"

The Medium Theratherm is the most compact of the three current models.

Its square 14" × 14" footprint makes it useful when a large 27-inch pad would create unnecessary overlap or be difficult to position.

Model: 1031-B Primary GTIN: 00190446715962

1032-B Standard — 14" × 27"

The Standard maintains approximately the same width as the Medium but nearly doubles its length.

That makes the 14" × 27" Theratherm the logical option when broad coverage is more important than compact positioning.

Model: 1032-B Primary GTIN: 00190446715979

1033-B Shoulder/Neck — 23" × 20"

The shoulder/neck model uses a contoured profile rather than simply increasing the dimensions of a rectangular heating pad.

Choose this version when the shape itself is important for positioning around the upper shoulder and cervical region.

Model: 1033-B Primary GTIN: 00190446715986

Medium vs. Standard vs. Shoulder/Neck

The heating-control platform is essentially the same buying proposition across the line; the primary decision is, therefore, coverage and shape rather than choosing different therapy technologies.

We carry several products that provide heat but use entirely unique workflows.

TheraMed uses a dampened sponge insert and four preset heat levels, while Hydrocollator HotPacs are passive packs designed to be heated in a compatible heating unit.

Choose Theratherm When

Choose Theratherm when you want a self-contained electric moist heating pad with programmable temperature and time.

Its digital controls are the distinguishing feature. There is no need to maintain a tank of heated water, and the user has substantially more control over settings than with a simple four-level heating pad.

Choose TheraMed When

Consider the TheraMed Professional Moist/Dry Heating Pad when simplicity and value are more important than programmable temperature control.

TheraMed provides both dry and moisture-assisted heat, four preset heat settings, two pad sizes, and automatic shut-off.

Choose Hydrocollator HotPacs When

Consider Chattanooga Hydrocollator Moist Heat HotPacks when equipping a clinic that routinely rotates several moist heat packs between treatment rooms.

HotPacs are passive packs rather than electric heating pads. They are designed to be maintained in compatible Hydrocollator heating units so multiple packs can remain treatment-ready during a busy clinical schedule.

A reusable gel pack is another option, but its workflow is fundamentally different.

Choose a reusable hot and cold gel pack when the ability to switch between heat and cold is more important than electronic control.

Choose Theratherm when the priority is a dedicated electric moist-heat system with controllable temperature and treatment time.

Theratherm occupies a useful middle ground between consumer-style heating pads and centralized clinical Hydrocollator systems.

A clinic does not need to maintain a hot-water heating tank to use it, yet its digital temperature and time controls provide more treatment-setting control than a basic plug-in pad.

This makes it especially relevant for the following environments:

Is Theratherm a heating pad or a heat pack?

Both terms are commonly encountered online. Chattanooga's official current product name is the Theratherm Digital Moist Heat Pack, while FDA device data classifies the product under powered heating pads, and Amazon uses both “heating pack” and “electric moist heat pad” terminology.

For product-search purposes, “Theratherm digital moist heating pad” is therefore an appropriate description of the same product family.

Does Theratherm require water?

Theratherm does not require a Hydrocollator hot-water heating tank. Chattanooga describes the flannel exterior as retaining moisture drawn from the surrounding air as the pad warms.

Follow the instructions supplied with the unit regarding preparation and use.

Is Theratherm the same as a Hydrocollator hot pack?

No.

A Theratherm is an electrically powered heating pad with a digital controller. A Hydrocollator HotPac is a passive reusable pack that is conditioned in a heated-water unit before application.

What temperature can Theratherm be set to?

a moist-heat temperature range of approximately 113°F to 166°F (45°C to 74°C).

The available temperature range describes the device's capabilities; it should not be interpreted as a recommendation to use the maximum setting for every application.

How long can the Theratherm timer be set?

Programmable treatment sessions of up to 60 minutes.

Actual treatment time should follow the current product instructions and appropriate professional guidance.

Does Theratherm shut off automatically?

Yes. Chattanooga lists automatic shut-off as a Theratherm feature.

What does the Theratherm lockout feature do?

The lockout mode is designed to help prevent inconsistent or unintended changes to programmed settings during a treatment session.

What is the largest Theratherm model?

Among the current models, the 1032-B Standard measures 14" × 27" and provides the greatest linear rectangular coverage.

The 1033-B Shoulder/Neck is 23" × 20", but its dimensions reflect its specialized contoured shape rather than a conventional rectangle.

What is the difference between 1031-B and 1032-B?

The principal difference is size.

1031-B is the 14" × 14" Medium model. 1032-B is the 14" × 27" standard model.

Both belong to the current Theratherm Digital Moist Heat line.

What is model 1033-B?

1033-B is the current Shoulder/Neck Theratherm, measuring approximately 23" × 20" and using a contoured format.

Important Heat-Therapy Safety Information

Powered heating devices can cause burns if used improperly.

Follow the current Theratherm instructions supplied with the product; select settings appropriate for the user and application; and monitor skin response during treatment. Do not treat the automatic shut-off as permission to sleep on the device or leave heat unattended.

Our Hot and Cold Therapies resource includes additional general heat- and cold-therapy considerations. We advise against sleeping on heating pads and emphasize timed, monitored applications.

Do not place an external heating device over a topical analgesic unless the medication's labeling specifically permits external heat.

Choose the Medium 14" × 14", Standard 14" × 27", or Shoulder/Neck 23" × 20" Choose the Theratherm size based on the area you need to cover.
