The pyrolysis principle combines a generously sized fuel chamber with electronically assisted combustion control and is suitable for appropriately designed hot water central heating systems in larger residential buildings, workshops, commercial properties, and similar applications.\u003c\/p\u003e \u003cp\u003eThe 180-liter filling chamber is loaded from the top and accommodates split logs up to 530 mm in length and 250 mm in diameter. The large fuel volume enables long burn phases of up to approximately 10 hours with suitable fuel quality and operating mode.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eCombustion is supported by an electronic control system with zPID technology and a rear-mounted flue gas fan. Boiler water and exhaust gas temperatures are monitored, and the fan speed is adjusted to the operating state. The PK BIO 49 achieves an efficiency of 89.0% when operating with split logs, meets boiler class 5 and Ecodesign requirements.\u003c\/p\u003e \u003cp\u003eCleaning of the tubular heat exchanger is assisted by an externally accessible operating lever. The cleaning mechanism can be structurally relocated to the left side of the boiler. An integrated cooling loop allows the connection of a thermal safety device to protect against overheating.\u003c\/p\u003e \u003cp\u003eThe door hinge is on the right as standard and can be ordered with left-hand hinging as a factory option. The flue gas outlet is vertical. A horizontal flue gas outlet variant is not available as a regular factory option for the PK BIO 49.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eTop loading makes it easier to insert larger logs and allows good use of the 180-liter fuel chamber. The flue gas fan supports controlled combustion and reduces the escape of flue gas into the installation room when refueling. The electronic boiler control system handles essential functions of combustion and temperature control.\u003c\/p\u003e \u003cp\u003eThe externally accessible cleaning lever facilitates regular cleaning of the tubular heat exchanger. The combustion chamber and flue gas passages remain accessible for the intended cleaning and maintenance work.
