Wolf condensing gas boiler CGW-2-14/100L with high-performance stratified storage tank

Consisting of a gas condensing boiler for operation with natural gas E, LL or LPG with a stainless steel domestic hot water heat exchanger and a stainless steel stratified storage tank in a 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 modulated, 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 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 swiveled out under system pressure without draining the heating water.
Easy maintenance due to coated heating water heat exchanger Wolf "ALUPro".
Quick assembly, 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 diverting valve for switching between heating and domestic hot water operation.
Control with gas burner control unit, electronic ignition and ionization flame monitoring, 10l expansion tank, mounting 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.
High-performance stratified storage tank made of stainless steel. Comfortable hot water preparation integrated, which outperforms a coiled-tube hot water storage tank with 100, 120 or 140 liters.
Hot water turbo with guidance and distribution system made of stainless steel for hot and cold water for quiet, radial water distribution and excellent hot water performance (European patent application).
High operating cost savings through efficient hot water preparation and innovative insulation technology with integrated annular gap system (utility model protection).
Controlled storage tank charging for highest energy efficiency through effective condensing utilization (European patent granted).
Compact design as a condensing unit and docked stratified storage tank for lowest assembly and installation costs.
Gas condensing central unit electrically and hydraulically ready for connection.
For installation, easily and quickly separable into two transportable modules of 35 kg and 19 kg.
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.
