Introducing the ULTRA THB auto-balancing actuator: Achieve Optimal Comfort and Energy Efficiency in Underfloor Heating

Are you tired of struggling with uneven heating and wasted energy in underfloor heating systems? We have exciting news for you: we are weeks away from launching the Ultra THB, our new, auto balancing Actuator by Salus Controls!
Developed in collaboration with experts from the University of Dresden, this groundbreaking product is set to revolutionize the way installers achieve optimal comfort and energy efficiency in underfloor heating systems.

The Challenge

Underfloor heating has become increasingly popular due to its comfort and aesthetic benefits. However, achieving an evenly heated space has always been a challenge for installers. Traditional underfloor heating systems often result in temperature imbalances, energy wastage, and reduced performance, leading to frustrated end-users.

This makes the Ultra THB a game-changer in the industry. This innovative device utilizes advanced technology to automatically balance the flow of hot water throughout the underfloor heating system, ensuring consistent temperatures and maximum comfort for end-users.

What’s Different with our new THB?

The Ultra THB Actuator from SALUS Controls brings significant advancements and improvements to underfloor heating installations. Here are the key features:

  1. Calibration-Free Operation: With the new Ultra THB, there is no calibration required anymore. The actuator works like any other actuator with a spring for closing. Every time the thermostat calls for heat, the actuator opens the valve and then closes it, measuring the force.

  2. Improved Valve Closing: The Actuator ensures reliable valve closing. It be utilized in a manner similar to a standard thermal actuator, but with the added benefit of a quick, high-precision motor. This combination of capabilities results in improved performance and greater control across diverse applications.

  3. Enhanced Balancing: Extensive tests conducted by the Computime Center of Excellence and Dresden University have proven that the Ultra THB Actuator achieves exceptional balancing at any time. It successfully balances under various conditions, including different flow temperatures, temperature loads, pump forces, room sizes, and even when sensors are wrongly installed.

  4. LED Indication: The THB features a new bi-color LED  for clearer indication. Green indicates normal functioning without any issues, while red serves as a visual alert indicating the presence of a problem.

Benefits and Advantages the Ultra THB for underfloor heating installations:

  • Enhanced Comfort: Experience consistent temperatures throughout space, eliminating temperature imbalances and cold spots, ensuring optimal comfort for end-users.

  • Energy Efficiency: The actuator optimizes the flow rate, reducing energy consumption and potentially leading to cost savings and a more environmentally friendly footprint.

  • Simplified Installation: The actuator does not require calibration, saving time and effort during installation. Its compatibility with a wide range of underfloor heating systems makes it a versatile choice for various projects.

  • Reliable Balancing: With its advanced technology and robust design, the Ultra THB Actuator maintains effective balancing, providing optimal performance under diverse conditions and installations.

Testimonials and Case Studies:
