With an output range of 4.5 to 15.0 kW, the boiler adapts its heat output to the current heat demand of the heating system within its modulation range.\u003c\/p\u003e \u003cp\u003eWood pellets are used as fuel. The SmartFire SF15 is suitable for building heating and can be integrated into a heating system with domestic hot water preparation. For pellet storage, three storage containers with capacities of 150, 240, or 440 liters are available.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026 Equipment\u003c\/h2\u003e \u003cp\u003eThe SmartFire SF15 features a stainless steel pellet burner with automatic ignition and automatic mechanical burner cleaning. Fuel is supplied via a screw conveyor and a backburn protection lock that structurally separates the pellet supply from the combustion chamber.\u003c\/p\u003e \u003cp\u003eThe GEMA Standard version is supplied without a lambda sensor, without automatic heat exchanger cleaning, and without automatic ash removal. The heat exchanger is cleaned mechanically via the designated cleaning mechanism. The automatic cleaning of the pellet burner remains an integral part of the boiler regardless of this.\u003c\/p\u003e \u003cp\u003eThe equipment includes weather-compensated control with a touch control panel as well as the hydraulic kit TV-Kit. The integrated thermostatic valve ensures a minimum return temperature of 55 °C and protects the boiler from low-temperature corrosion.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003ePellet feeding, ignition, and burner cleaning run automatically. As a result, regular operation focuses on checking and refilling the pellet supply, mechanical heat exchanger cleaning, and the prescribed cleaning and maintenance work.\u003c\/p\u003e \u003cp\u003eWith three different container sizes, the SmartFire SF15 can be adapted to various space conditions and desired pellet supplies. The 150-liter container offers the smallest footprint, while the 240 and 440 liter variants provide larger fuel supplies.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026 Compatibility\u003c\/h2\u003e \u003cp\u003eThe SmartFire SF15 Standard is designed for water-based central heating systems. Hydraulic integration is carried out taking into account the required return temperature of at least 55 °C. In this version, the boiler has a maximum permissible operating pressure of 1.5 bar; the separately documented SF15-3-bar version is not part of this article.\u003c\/p\u003e \u003cp\u003eWith a 150-liter storage container, the overall dimensions are 985 × 1490 × 760 mm. The 240-liter version measures 1180 × 1490 × 805 mm. With a 440-liter storage container, the overall dimensions are 1345 × 1490 × 1015 mm.\u003c\/p\u003e \u003cp\u003eFor automatic pellet supply from a larger or spatially separated pellet storage, the pneumatic HKS Lazar Vacum pellet conveying system can be used as separate accessory.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0
