Heating Innovation: The Radiant Auto-Balancing System (RABS) introduces the ability to monitor the temperature of every return circuit in a radiant system. Coupled with the monitoring of each zone’s air temperature via wireless thermostats, the control actuates flow of conditioned water to each loop using a learning algorithm to increase the efficiency of a radiant installation. Circuit lengths no longer need to be designed to be similar lengths or manually balanced using flow controls on the manifold. Even though designing similar length circuits is still best practice, designs rarely account for furniture and temporary floor covering. The system maintains set temperatures through changes in these variables without user input, giving designers more flexibility without loss of efficiency.

This innovation will offer a desirable solution to customers seeking high efficiency radiant. The system also incorporates more digitalization of plumbing for monitoring by end users, something that is sought after more and more by customers looking to have more interesting and useful data related to their system performance. Additionally, this system will save installers valuable time when balancing a radiant system. Once the system is connected to a manifold and the web application, the customer has the ability to make changes and monitor temperatures.

Plumbing Innovation: The Caleffi AngleMix™ 520 series thermostatic mixing valve accurately controls mixed water temperature in residential and commercial domestic hot water systems. It is the industry’s only thermostatic mixing valve with an angle-styled body. This geometry minimizes the number of elbows required which reduces overall installation cost. Additionally, AngleMix is the industry’s only thermostatic mixing valve that can close off its hot and cold ports at 100% tightness, preventing temperature creep or droop.

The innovative Caleffi AngleMix™ 520 series easily mounts at the tank-type, or tankless type water heater outlet and the angle-style body mixed temperature outlet is in line with the water heater outlet. This facilitates straight-line piping which reduces pipe elbows and overall space required for installation. The AngleMix has a lockable set point adjustment knob and includes a temperature gauge on the mixed temperature outlet for instant verification of temperature. The precision engineered anti-scale internal components minimize service requirements, assure smooth operation and long life, and compensate for temperature and pressure fluctuations of the incoming hot and cold water. Available in a wide variety of end connections, the angle style body design is compatible with all common pipe types and connection styles from ½” to 1” sizes. AngleMix is certified to ASSE 1017 standard for point of distribution domestic water systems.
