Wolf COB-2-15 B30 ComfortLine Oil Condensing Boiler, with oil fan burner

Oil condensing boiler for heating with connection option for storage water heater, tested according to DIN EN 303 / DIN EN 304 / DIN EN 15034 / DIN EN 15035 as well as EC Directive 92/42/EEC (efficiency directive) and 73/23/EEC Low Voltage Directive and 2004/108/EC (EMC Directive) with electronic ignition and electronic flue gas monitoring, for low-temperature heating and hot water preparation according to EN12828.
Meets the limits of the "Blue Angel" energy efficiency label 4 stars. Extremely low-emission and efficient combustion with complete condensation of the flue gases, high seasonal efficiency for best possible energy utilization.
Low electrical energy consumption.
Operation with standard and low-sulfur heating oil EL.
Suitable for a bio-oil content (FAME) of up to 30%, based on the heat provided by the system.
Two-stage blue flame burner for room air dependent and room air independent operation.
Oil connection only with single-line system. (Pipe max. 6mm)
High-quality heat exchanger made of robust aluminum-silicon alloy, long service life, low maintenance and no minimum circulation water quantity required.
Casing powder-coated, color: white RAL 9016
Boiler fully assembled and cased, packed on a pallet, easy transport and easy installation.
Can be installed directly on the wall, thus requiring little space, no lateral distances required, easy access to all components from the front, easy operation and maintenance.
Control fully wired and integrated into the boiler, prepared for combination with weather-compensated temperature controllers.
