Wolf Condensing Boiler Unit CGS-2-20/150R with High-Performance Coiled Tube Cylinder

Wolf condensing boiler CGS-2 consisting of gas condensing boiler for operation with natural gas E, LL or LPG with stainless steel domestic hot water heat exchanger and coil in modular design.
Factory set for natural gas E, LL, convertible to LPG.
Tested according to EC directives and DIN EN 483 for heating systems according to DIN EN 12828 with flow temperatures up to 90° C and 3 bar permissible operating pressure, suitable for continuously lowered operation down to room temperature.
Power modulating, gas-adaptive, self-calibrating combustion control with premix burner for extremely low pollutant emissions and changing gas quality, closed combustion chamber for room air-dependent and independent operation.
Speed-controlled fan.
Casing white RAL 9016 powder-coated.
High standard efficiency up to 110% (Hi) / 99% (Hs) for best possible energy utilization.
Conditions of the "Blue Angel" environmental label according to RAL UZ61 when operated with natural gas.
Low CO and NOx emissions.
Continuously modulating heat output from 1.8 kW.
Lowest power consumption in standby mode of 3W.
Modulating high-efficiency pump (EEI < 0.23) for automatic adaptation of the volume flow.
For maintenance, the heating water heat exchanger can be swiveled out under system pressure without draining heating water.
Easy maintenance thanks to coated heating water heat exchanger Wolf "ALUPro".
Fast installation, easy operation and maintenance with convenient access to all components.
Easy flue gas measurement from the outside without opening the device.
Optimal condensing technology utilization through spread control without overflow valve.
Suitable for multiple occupancy according to DVGW worksheet G635 due to integrated flue gas backflow prevention device.
Warning message for low water pressure by electronic heating water pressure sensor.
Integrated 3-way diverter valve for switching between heating and domestic hot water operation.
Control with gas burner control, electronic ignition and ionization flame monitoring, 10l expansion vessel, hanging bracket, pressure gauge for the heating circuit, electronic pressure sensor, integrated air/flue gas duct connection piece with concentric connection 60/100 mm with measuring openings. Controlled cylinder charging for highest energy efficiency through effective condensing technology utilization (European patent granted) with CGS-2-20/150R a bathtub of approx. 200 liters / 40° C can be filled in 10 minutes, with CGS-2-14/150R approx. 180 liters / 40° C are achieved high performance coefficient NL = 1.4 or
1.8 when heating from 10° C to 60° C lowest heat losses due to highly efficient insulation technology in 24 hours only 1.47kWh energy consumption compact design as a condensing unit with coil storage tank.
Easily separable into two modules of 35kg and 80kg for installation Storage tank charging via robust heating coil with generously dimensioned heat exchanger surface for short heating times Prepared for the installation of the LAN/WLAN module ISM-7i for communication via smartphone, laptop, PC or the Internet.
An operating module BM-2 or a display module AM is required for operation.
