Gas condensing boiler MGK-2 170 equipped for natural gas E, WOLF # 8752242

Conversion to LPG can be carried out by Wolf Customer Service.
Gas condensing boilers according to DIN EN 15502, as well as according to valid EC directives, for hot water heating systems with heating circuit pumps according to DIN EN 12828 for room air-dependent or room air-independent operation, high-performance heat exchanger made of robust aluminum-silicon alloy with high corrosion resistance and standard efficiency up to 110%.
Speed-controlled combustion air fan with a large, efficient modulation range of 17-100% reduces cycling to a minimum.
Sound-optimized gas premix burner with pneumatic gas-air compound for extremely low-emission and quiet combustion.
Gas valve with integrated filter and fault indicator.
A condensate trap, a backflow preventer, and an exhaust gas pressure switch are already integrated.
Water shortage protection by water pressure sensor already integrated in the boiler.
Bypass valve or return temperature increase not required as zero flow is detected by numerous temperature and pressure sensors.
Optimal condensing technology utilization through intelligent pump control.
Boiler circuit pump with PWM or 0-10V interface required.
Siphons, condensate trap and condensate hoses already pre-assembled.
Up to 5 boilers can be cascaded.
Backflow preventer for cascade operation already integrated in the boiler.
Combustion air supply, exhaust gas, gas and heating flow and return are led out of the top of the boiler, so that the boiler can be placed space-savingly on two walls.
Good accessibility for easy maintenance and low space requirement in case of service.
The boiler is completely factory-clad with high-quality, powder-coated steel sheet.
The internal PUR-ether acoustic and thermal insulation makes the boiler whisper-quiet and at the same time increases efficiency to a maximum.
Boiler is supplied completely clad, thermally insulated and electrically and hydraulically pre-assembled.
The boiler can be entered on all sides with a pallet truck, which enables 1-man installation.
Installation also possible in confined structural conditions, because the device can be disassembled into a gas-air compound and a heat exchanger unit.
Crane transport possible.
Safety group with manometer and safety valves can be mounted directly from the accessories.
Maximum pressure limiter can be integrated into the safety group.
Basic control with gas burner control unit, electronic ignition, ionization flame monitoring and power-dependent speed control of the combustion air fan.
The stepless speed control combined with intelligent control algorithms enables the boiler to always provide the desired heat output at the optimal operating point.
Collector sensor for hydraulic separator or plate heat exchanger can be connected directly.
Prepared for combination with weather-compensated temperature controllers.
0-10V connection for device control via building management system available.
Parameterizable input and output for e.g. fault message output available.
If required, 2 further parameterizable inputs and outputs can be installed with the I/O expansion module.
Connection for external safety devices, e.g. maximum pressure limiter, available on the control unit.
Remote monitoring function via internet and smartphone via ISM7i accessory.
