It is intended for hydronic central heating systems in residential buildings, single-family homes, as well as suitable commercial and workshop areas. The boiler output must be matched to the building\u0026#39;s heat load.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe boiler body is made of welded P265GH boiler steel. In the loading chamber, the wood is degassed; the resulting wood gas then burns in a separate combustion chamber. The ecoMAX-800D control system integrates, among other things, boiler, buffer, and flue gas temperature sensors as well as the fan and pumps into the operating management. An integrated cooling coil with a BVTS temperature valve serves as thermal overheating protection.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe 110-liter loading chamber and the loading door with 405 × 350 mm dimensions support comfortable manual loading. A flame viewer in the combustion chamber door allows visual inspection of the combustion process. The separate supply of primary and secondary air supports controlled wood gas combustion.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eFor the 18 kW version, a buffer tank with at least 800 liters is required. The return temperature to the boiler must be at least 55 °C. The Caldo S-I can be used in open heating systems as well as in appropriately protected closed systems. Domestic hot water preparation can be realized via a professionally integrated heat exchanger.\u003c\/p\u003e \u003c\/div\u003e \u003cstyle\u003e .product-th{margin-top:2rem}.product-th h2{margin:0 0
