NEW! KTE412 HWC KIT AND KTE112 CONNECTION KIT!

2026-06-02

Here come two hot product updates! The KTEx00 series includes an HWC kit and a connection kit, both perfectly suited for our thermostatic valves.

The brand new KTEx00 series is here! KTE412 HWC-kit for UPTT and KTE112 connection kit for VTA_1900x600.jpg

To simplify installation and optimize performance in larger domestic hot water systems, ESBE is launching two new accessories: the KTE412 HWC kit (HWC = hot water circulation) and the KTE112 connection kit. The products are developed to complement our thermostatic valves with G1" (KTE112) or G1¼" (KTE412) connections and help create reliable, energy-efficient, and flexible solutions.

 

KTE412 HWC kit – easy and safe integration in hot water circulation

KTE412 is a connection set with external thread and integrated non-return valves, designed for easy connection of, for example, UPTT522 to systems for hot water circulation (HWC).
A correctly dimensioned and balanced HWC system ensures that the correct temperature is maintained throughout the domestic hot water system. This reduces the risk of legionella growth, improves comfort with immediate access to hot water, and minimizes unnecessary flushing — which in turn saves large amounts of water over time.
KTE412 is optimal together with UPTT522, but thanks to the standard G 1¼" connection, it can also be combined with VTA522 and VTA552. It is especially well suited with the UPTT500 series in larger applications where high temperature accuracy and safe operation are crucial.
Advantages in practice:
●    Integrated non-return valves for correct flow direction
●     Simplified installation in HWC systems
●    Secure temperature maintenance throughout the system
●    Reduced water consumption and increased comfort
The result is a reliable installation that meets both hygiene requirements and comfort expectations.

KTE112 Connection kit – parallel installation for higher capacity

KTE112 is a connection kit with external thread on the system side and union nut on the valve side, developed for installing two identical thermostatic mixing valves in parallel.
In larger domestic hot water systems where high flow requirements exist, a single valve may be insufficient to achieve the desired Kvs value without compromising control accuracy. By connecting two valves in parallel, the system can reach a higher total Kvs while maintaining the high temperature precision of smaller valves.
The solution provides:
●    Higher capacity at high flows
●    Stable temperature control
●    Good performance even with varying and low flows
KTE112 is compatible with the valve series VTA522, VTA552, VTA572, VTS522, and VTS552 with G1" connection. This allows you to choose the valve that best meets your system’s requirements while building a tailored solution for larger hot water systems.

Flexibility without compromising safety
With KTE412 and KTE112, we provide well‑designed accessories that simplify installation and expand the application range of our thermostatic mixing valves. Whether the focus is hygienic safety in an HWC system or high capacity in larger hot water installations, the products offer a technically robust and future‑proof solution.
For you as an installer, this means fewer compromises and a system that delivers stable temperature, high safety, and long-term operational reliability.
