For corner installation
Corner fireplace insert with a nominal heat output of 10 kW for installation where the fire should be visible from the front and the side. In this version the side glass is on the left side; the version with the glass on the right has the same parameters. Heats approximately 80–100 m² in a building with good insulation standard.
P265GH boiler steel plate, 3 mm
All components of the insert are made from P265GH boiler steel plate, 3 mm thick. This means the insert can be built into a warm, heat-storage (accumulation) enclosure, including a hypocaust-type system without convection grilles. The combustion chamber is lined with ceramic concrete, 3 cm thick, has two baffles and a steel ash pan, and the door uses a copper closing system.
Combustion and emissions
Closed combustion chamber with flue-gas afterburning, fuel: hardwood. At nominal output the insert reaches an efficiency of 80.1 % and class A+. Emissions: particulate matter 37, organic gaseous compounds 48, carbon monoxide 673 and nitrogen oxides 95 mg/m³. The insert is suited to homes with heat-recovery ventilation.
Compliance with standards
Heating Holding of Bydgoszcz declares that the insert complies with the harmonised standard EN 13229 and with the Ecodesign requirements of Commission Regulation (EU) 2015/1185. Testing was carried out by notified body No. 1450, Kraków. The declaration of conformity can be downloaded below.
The version without a side glass is the HEATING 620 straight (80.7 %). Higher output, 11 kW: HEATING 720 corner.
