Systematic heating
The module
The further the water tapping points are from the hot water producer, the more important a good circulation set is. While conventional systems send some hot water through the pipes from time to time, the ETA circulation set is only active when there's a demand. That saves energy.
This is how the circulation is activated:
Technology
Corresponds to DIN DVGW or ÖNORM B5014-3
FWM 33:
Tap output 33 l/min. with 45 °C at 60 °C buffer temperature
Pressure loss module drinking water side:
33 l/min = 580 mbar (5.8 mWs)
15 l/min = 150 mbar (1.5 mWs)
FWM 44:
Tap output 44 l/min. with 45 °C at 60 °C buffer temperature
Pressure loss module drinking water side:
44 l/min = 560 mbar (5.6 mWs)
20 l/min = 160 mbar (1.6 mWs)
Plastic cap H=600 mm, W=400 mm, D=190 mm
Cascadable for greater tap outputs
Water side:
Control system with safety plug:
The components inside the module are already pre-wired.
Control system contains 2 freely available sensors inputs (for poss. connection of the buffer sensors) and an output for the circulation set.
Loosely enclosed:
CAN-Bus line L=10 m for connection with ETA boiler control system
