The pyrolysis principle combines a large fuel chamber with electronically assisted combustion control and is suitable for appropriately designed hot water central heating systems in residential buildings, workshops, and comparable applications.\u003c\/p\u003e \u003cp\u003eThe 130-liter filling chamber is conveniently loaded from the top and accommodates split logs up to 530 mm in length and 250 mm in diameter. Under suitable operating conditions, the large fuel chamber enables long burn phases of up to approximately 8 hours.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eCombustion is supported by the ST 86 zPID electronic control and a rear-mounted flue gas fan. Boiler water and exhaust gas temperatures are recorded, and the fan output is adjusted according to the operating state. The PK BIO 30 achieves an efficiency of 89.0% when operating with split logs, meets boiler class 5, and complies with Ecodesign requirements.\u003c\/p\u003e \u003cp\u003eCleaning of the tubular heat exchanger is assisted by an externally accessible operating lever. The operating mechanism can be structurally relocated to the left side of the boiler. An integrated cooling loop enables the integration of the 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 30.\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 available fuel space. The flue gas fan supports flue gas routing during combustion and when reloading. The electronic control handles essential functions of combustion and temperature regulation.\u003c\/p\u003e \u003cp\u003eAn externally accessible operating lever is available for regular cleaning. The combustion chamber, heat exchanger, and flue gas paths remain accessible for the intended cleaning and maintenance work.
