It is suitable for heating systems where a robust, simply designed boiler without a fan and without electronic controls is required.\u003c\/p\u003e \u003cp\u003eThe boiler is designed for integration into central hot water heating systems and can be operated with gravity circulation or pump circulation depending on the system design. The specific power selection and system design should always match the heating load, buffer tank, and existing flue system.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026 Equipment\u003c\/h2\u003e \u003cp\u003eThe Rojek KTP 30 operates as a manually loaded natural draft boiler with adjustable primary and secondary air supply. Combustion is controlled via the air supply and the draft regulator, not by an electric fan. This keeps the technical design deliberately simple and straightforward.\u003c\/p\u003e \u003cp\u003eThe boiler body consists of a welded steel construction. The grate is water-cooled, the combustion chamber is designed for split logs, and the boiler features a large loading door as well as separate cleaning areas. A cooling loop is provided for overheat protection.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Advantages\u003c\/h2\u003e \u003cp\u003eIn daily use, the Rojek KTP 30 prioritizes ease of operation. The manual loading, mechanical power regulation, and easily accessible cleaning areas make the boiler appealing to operators who prefer a straightforward, robust solid fuel technology.\u003c\/p\u003e \u003cp\u003eBy operating without electric fan technology, the boiler is less dependent on electronic components. For clean and material-friendly operation, dry firewood, suitable chimney draft, adequate return temperature, and regular cleaning remain crucial.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026 Compatibility\u003c\/h2\u003e \u003cp\u003eThe Rojek KTP 30 is integrated into a water-based heating system. The water connections are designed as G 2\", and the flue gas connection is 160 mm or 159 mm at the boiler nozzle. For convenient and professional operation, combining it with a buffer tank is advisable.\u003c\/p\u003e \u003cp\u003eThe manufacturer specifies a recommended buffer tank volume of 1200 liters for the KTP 30. The specific integration should be planned by a qualified specialist, particularly regarding return temperature boosting, safety group, thermal drain safety, chimney draft, and hydraulic integration.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0 1rem}.product-th__table{width:100%;border-collapse:separate;border-spacing:0}.product-th__table td{padding:.95rem 1rem;vertical-align:top}.product-th__label{font-weight:700;width:38%;color:#213670}.product-th__value{color:#1f2937}.product-th__table tr:nth-child(odd) td{background:#f4f7fb}.product-th__table tr:nth-child(even) td{background:#fafbfd} \u003c\/style\u003e \u003cdiv class=\"product-th\"\u003e \u003ch2\u003eTechnical Data at a Glance\u003c\/h2\u003e \u003cp\u003eThe most important technical data of the Rojek KTP 30 for classification in the heating system.\u003c\/p\u003e \u003ctable class=\"product-th__table\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eNominal Output\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e30 kW\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eFuel\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eWood\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eCombustion Technology\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eNatural Draft\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEfficiency\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003e80.8 %\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eEnergy Efficiency Class\u003c\/td\u003e \u003ctd class=\"product-th__value\"\u003eA+ for Wood\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"product-th__label\"\u003eMax.
