It offers high flow rates and consistent performance, making it the ideal choice for temperature control. Domestic Hot Water (DHW) and the management of circuits underfloor heating small in size.
The VTA320 Series is the preferred choice when a anti-burn safety function mandatory in the ACS supply line.
✨ Key Benefits: Control, Flow and Safety (EEAT)
ESBE's engineering guarantees high flow capacity and long-term reliability.
-
Guaranteed Scald Protection: Its safety feature automatically cuts off the hot water supply in case of a failure or interruption of the cold water supply. This protects the end user from accidental scalding.
-
Versatile Temperature Regulation: It allows a precise regulation range of 35 to 60°C, ideal for complying with legionella regulations and comfort requirements.
-
High Flow Capacity: Designed to offer optimized flow, being compatible with DHW systems with or without recirculation (HWC).
-
Easy Installation and Maintenance: The availability of connection kits with adapters and check valves (optional) simplifies assembly and any future servicing.
-
Universal Compatibility: Suitable for DHW, closed systems and underfloor heating circuits (considering flow rate and temperature range).

❓ Frequently Asked Questions (FAQ)
1. What is the main factor to consider if I use the VTA320 for underfloor heating?
Although the VTA320 is compatible with underfloor heating, the most important factor to consider is the temperature range (35-60°C) and the required flow rate (Kvs). Ensure that the temperature range meets the needs of your underfloor heating and that the flow rate is sufficient, as larger systems may require other ESBE series.
2. How does the anti-burn safety function work?
The internal thermostatic mechanism detects any loss of pressure or flow in the cold water line. Upon sensing this anomaly, it reacts immediately by closing the hot water inlet port, preventing the supply of water at a dangerously high temperature.
3. Is the VTA320 suitable for drinking water?
Yes, the VTA320 series is designed and manufactured with materials that make it fully suitable for use with fresh and drinking water, as well as closed systems and glycol water.
