Wolf CGS-2 gas condensing central heating system, consisting of a gas condensing boiler for operation with natural gas E, LL or LPG, with stainless steel hot water heat exchanger and stratified storage tank 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 modulatingly controlled, 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" ecolabel according to RAL UZ61 when operating 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 adjustment of the volume flow.
For maintenance, the heating water heat exchanger can be swung 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 utilization through spread control without overflow valve.
Suitable for multiple occupancy according to DVGW worksheet G635 due to integrated flue gas backflow prevention.
Warning message for low water pressure by electronic heating water pressure sensor.
Integrated 3-way diverter valve for switching between heating and hot water operation.
Control with gas burner control, electronic ignition and ionization flame monitoring, 10l expansion vessel, hanging brackets, pressure gauge for the heating circuit, electronic pressure sensor, integrated connection piece for the air/flue gas duct with concentric connection 60/100 mm with measuring openings.
Stratified storage tank made of steel, enameled.
The "Turbostop system" in the stratified storage tank ensures comfortable hot water preparation, which surpasses a coiled pipe domestic hot water storage tank with 120, 160 or 200 liters.
Controlled storage tank charging for highest energy efficiency through effective condensing utilization (European patent granted).
High performance figure NL = 1.3 to 2.5 when heating from 10° C to 60° C.
Lowest heat losses due to highly efficient insulation technology, only 1.0 kWh energy consumption in 24 hours.
Compact design as a condensing unit with stratified storage tank.
Easily separable into two modules of 35 kg and 49 kg for installation.
Prepared for the installation of the LAN/WLAN module ISM-7i for communication via smartphone, laptop, PC or the internet.
For operation, a control module BM-2 or a display module AM is required.
