Heating Units & Hydrocollators
Professional heating units for repeated use
This range includes professional heating systems such as the Chattanooga E-1, E-2, M-2, M-4, and SS-2 Hydrocollator Heating Units. These products are better suited to clinics and treatment spaces that need more than a simple home heat option.
Choose the right hydrocollator size
Some buyers want a smaller unit for lighter use, while others need a larger hydrocollator for busier treatment environments. Comparing unit size and clinic workflow can make it easier to choose the right heating system.
What to consider before buying
When comparing therapeutic heating systems, it helps to think about treatment volume, available space, whether you need a cart or other support equipment, and how much reusable moist heat capacity your clinic needs.

Frequently Asked Questions
What is a hydrocollator and how does it work?
A hydrocollator is a professional heating unit that uses hot water to heat reusable HotPacs. The unit maintains the water at a controlled temperature so HotPacs are always ready for moist heat therapy without needing to be reheated between patients.
What is the difference between a heating unit and a hydrocollator?
In healthcare settings, the terms are often used interchangeably. A hydrocollator specifically refers to a water-based heating unit designed to heat and store HotPacs for moist heat therapy, whereas “heating unit” is a broader term that can include other types of heat devices.
What are hydrocollators commonly used for?
Hydrocollators are commonly used in physiotherapy clinics, chiropractic offices, rehabilitation centres, and hospitals to deliver moist heat therapy. This type of heat is often used to help reduce muscle stiffness, ease pain, relax muscles, and improve circulation.
How do I choose the right hydrocollator size for my needs?
Choosing the right size depends on available space and how often heat therapy is used. Smaller countertop units work well for low-volume use or home settings, while floor-standing units with higher capacity are better suited for busy clinics and hospitals treating multiple patients at the same time.
Can hydrocollators be used at home?
Some compact hydrocollators are used in home settings, especially by individuals familiar with moist heat therapy. Home users should ensure proper placement, follow manufacturer instructions, monitor water levels, and always use protective covers when applying HotPacs.
Are hydrocollator heating units designed to stay on all day?
Yes. Professional hydrocollators are designed for continuous operation and are commonly left powered on throughout the day so HotPacs remain at therapeutic temperature when needed.
Do hydrocollators require plumbing or a water hookup?
No. Most hydrocollator heating units do not require plumbing. They are manually filled with water and can be placed anywhere a standard electrical outlet is available.
Are HotPacs included with hydrocollator heating units?
Many hydrocollators include a set of HotPacs, but the number and type vary by model. Product listings will indicate exactly how many HotPacs are included with each unit.
Are protective covers required when using HotPacs?
Yes. A protective terry cover is required between the HotPac and the skin to ensure safe and effective treatment. Covers are selected based on HotPac size and are sold separately.
What is the difference between countertop and floor-standing hydrocollators?
Countertop hydrocollators are compact and suited for smaller spaces or lighter use. Floor-standing hydrocollators offer greater capacity and mobility, making them better for clinics or facilities with higher daily treatment volume.
How long do HotPacs stay warm after being removed from the unit?
When properly wrapped, HotPacs typically retain therapeutic heat for up to 20–30 minutes, depending on the pack size and treatment environment.
Are hydrocollators safe to use in clinical settings?
Yes. When used according to manufacturer instructions, hydrocollators are a well-established and safe method of delivering moist heat therapy in professional healthcare environments.
