Wolf Condensing Boiler TGB-2-30 Equipped for Natural Gas E/H and LL

Gas condensing boiler for room air-dependent and room air-independent operation with E, LL and LPG.
Factory-set for natural gas E.
For space heating and domestic hot water preparation with a separate domestic hot water cylinder, e.g. TS-160, TR-160 (for TGB-2-20/30).
Floor-standing unit, optimised for easy replacement of existing units due to two flue gas connection options without additional accessories.
Connection possibility at the top for wall mounting or at the back for using the existing flue gas connection. Patent pending.
All appliance connections optimised for the replacement of existing systems.
Continuously modulating heat output, e.g. from 2.9 kW for TGB-2-20.
Low CO and NOx emissions.
Premix burner for natural gas and LPG, control with gas burner control unit, electronic ignition and ionisation flame supervision. Speed-controlled fan.
Extended condensing boiler utilisation through spread control.
Seasonal space heating efficiency 94%.
High-quality heat exchanger made of robust aluminium-silicon alloy, long service life, low maintenance. Optimised 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 ports.
Easy external flue gas measurement and control of the setting on the gas valve without opening the appliance.
Automatic de-aerator.
No mechanical switches in the heating water.
White RAL 9016 powder-coated casing with design stripes.
Minimum noise level due to insulated casing.
Boiler fully assembled, pre-wired and cased, packed on a pallet, easy transport and light installation.
Can be placed directly against 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 fasteners for easy maintenance.
Can be cascaded three or five times (TGB-2-20) and intelligently hybrid-capable 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
