Wolf Gas Condensing Boiler TGB-2-20 Equipped for natural gas E/H and LL

Gas condensing boiler for room air-dependent and room air-independent operation with natural gas E, LL and liquid gas.
Factory-set for natural gas E.
For space heating and hot water preparation with separate hot water cylinder, e.g. TS-160, TR-160 (for TGB-2-20/30).
Floor-standing unit, optimized for easy replacement of existing units with two flue gas connection options without requiring additional accessories.
Connection option at the top for wall mounting or at the back for using the existing flue gas connection. Patent pending.
All appliance connections optimized for the replacement of existing systems.
Continuously modulating heating output, e.g. from 2.9 kW for TGB-2-20.
Low CO and NOx emissions.
Premix burner for natural gas and liquid gas, control with gas burner automatic, electronic ignition and ionization flame monitoring. Speed-controlled fan.
Extended condensing boiler utilization through spread control.
Seasonal space heating efficiency 94%.
High-quality heat exchanger made of robust aluminum-silicon alloy, long service life, low maintenance. Optimized heating water content 7.5l. Efficient and no minimum circulating water quantity required.
Heat-resistant combustion chamber cover with natural vermiculite insulation. Easy maintenance and cleaning of the heating water heat exchanger under system pressure without draining heating water.
Electronic pressure sensor.
Integrated flue gas backflow prevention for flue gas cascades, air/flue gas duct connection piece DN80/125 concentric with measuring openings.
Easy external flue gas measurement and control of the setting on the gas valve without opening the appliance.
Automatic deaerator.
No mechanical switches in the heating water.
Casing white RAL 9016 powder-coated with design stripes.
Minimal noise due to insulated casing.
Boiler fully assembled, pre-wired and cased, packed on a pallet, easy transport and easy installation.
Can be installed directly on the wall, thus requiring little space, installation possible without side clearances.
Easy operation and maintenance with convenient access to all components from the front and top at a comfortable height.
Flip&Clean device with comfortable storage position and practical bayonet locks for easy maintenance.
Cascadable in three or five stages (TGB-2-20) and intelligently hybrid-compatible with WOLF heat pumps.
Prepared for the installation of the LAN/WLAN module WOLF Link home for remote maintenance.
For operation, a BM-2 control module integrated into the boiler or an AM display module is required.
