This is where the DSX Twin is used.

Shower in spa area
Wellness shower
Bath tub

For maximum shower convenience.

This solution combines two E-comfort instantaneous water heaters to supply one or more tap points with high hot water requirements (minimum flow rate per single tap: 6 l/min), e.g. a wellness shower. The devices are synchronised via the special Twin software, temperature settings are automatically taken over by both devices.

Complete set of two fully electronically controlled high-tech instantaneous water heaters DSX with a special installation frame and remote control
With special piping set and mounting material for inside wall mounting
Depending on the set nominal output (kW) of the DSX units, the flow rate is doubled.
Always precise temperatures between 20 °C and 60 °C thanks to TWIN TEMPERATURE Control TTC^® and dynamic flow rate control SERVOTRONIC^®.
Cabinet dimensions (height × width × depth): 81.6 × 60.3 × 14 cm
