It absorbs thermal energy, stores it, and releases it according to the demand of the connected heating system.\u003c\/p\u003e \u003cp\u003eThe combination of 300 liters of storage volume and a heat exchanger surface area of 3.2 m² supports the integration of various heat generators. The tank volume is intended for heating water or a suitable neutral heat transfer medium and is not approved for the direct storage of drinking water.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe integrated heat exchanger has a surface area of 3.2 m² and a capacity of 15.8 liters. A heat exchanger output of 69.0 kW and a flow rate of 1,720 liters per hour are specified. The actual transferable output depends on the system temperatures, the flow rate, and the hydraulic integration.\u003c\/p\u003e \u003cp\u003eMultiple side connection positions allow flexible integration into different system concepts. Sensor connections at various tank heights support temperature detection. A separate sleeve can be used for an optional electric heating element if suitably designed.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eDespite the 300-liter storage volume, the standing cylindrical design requires only a comparatively small footprint. The removable thermal insulation facilitates installation and reduces heat losses during operation.\u003c\/p\u003e \u003cp\u003eDifferent connection and sensor positions make it easier to adapt to the respective heating system. Energy efficiency class C and a standby heat loss of 97.2 watts characterize the energy properties of the 300-liter version.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe Defro DBO 300 can be used in closed heating systems with suitable boilers, heat pumps, and other heat generators. Integration into appropriately planned solar thermal systems is also generally possible.\u003c\/p\u003e \u003cp\u003eStorage volume, heat exchanger, flow rate, pressure conditions, and system temperatures must match the respective system concept.
