## Summary description

Herz 3-way thermostatic mixing valve TEPLOMIX DN32 with G 1 1/2 connection, designed to raise boiler return temperature. Brass construction provides corrosion resistance and durability. The valve mixes hot and cooler return water to maintain set return temperature, protecting condensing boilers and improving system efficiency in central heating circuits.

## Long description

The Herz TEPLOMIX 3-way thermostatic mixing valve DN32 with G 1 1/2 connection is designed to increase boiler return temperature in central heating systems. Constructed from brass, the valve mixes hot supply water and cooler return water to maintain a preset return temperature, which helps prevent condensation in boilers and supports stable operation of heating circuits. The compact design and threaded connection allow integration into boiler return lines and closed heating networks.
Advantages
The brass body provides corrosion resistance and mechanical durability for long-term operation in water-based heating systems. The thermostatic element ensures automatic and continuous regulation of return temperature without electric power or external control, offering reliable protection against flue gas condensation in low-temperature operation. The 3-way mixing configuration enables precise blending of flow and return water to achieve and keep the required temperature, improving overall system efficiency.
Suitable for
Increasing return temperature to protect condensing and non-condensing boilers
Integration in central heating circuits and boiler return lines
Domestic and small commercial heating systems requiring passive temperature control
Key specifications
Connection size: DN32 with G 1 1/2 threaded connection
Type: 3-way thermostatic mixing valve for return temperature control
Material: brass valve body for corrosion resistance
Operation: thermostatic element for automatic regulation without external power
Application: designed for water-based central heating systems and boiler return lines
How to use
Install the mixing valve into the boiler return line according to the flow direction indicated on the body and ensure tight threaded connections. Set the desired return temperature following the manufacturer's adjustment procedure for the thermostatic element; the valve will then blend hot supply water and cooler return water to maintain that temperature. Commission the system by purging air from the circuit, checking for leaks, and verifying stable temperature control during normal operation.
Usage recommendations
For reliable performance, install the valve in an accessible location for adjustment and maintenance. Use appropriate thread sealant on connections and follow local regulations for heating system installation. Periodic inspection for scaling or debris is recommended in systems with untreated water to ensure smooth thermostatic operation.
