❓ Frequently Asked Questions (FAQ)
1. Which ESBE series should I choose for my underfloor heating?
If your circuit is small or standard sized, the VTA322 Series (20-43°C) It is suitable and efficient. If you need to handle a High Flow due to the size of the installation or requires a slightly higher temperature range, the VTA572 Series (20-55°C) It is the superior professional option.
2. Does the anti-scald safety function apply to underfloor heating?
Yes, in the context of underfloor heating, the safety function protects the piping system and the floor from accidental overheating. In the event of a malfunction that could cause the temperature to spike, the valve cuts off the heat supply to prevent costly damage.
3. Is the VTA572 compatible with cooling applications?
Yes. Although the main model for underfloor heating has a range of 20-55°C, the VTA572 Series also includes versions with temperature ranges of 10-30°C, making it suitable for underfloor heating circuits. refrigeration on the same floor or ceiling.
