Its main function is to compensate for volume changes in the water when it heats and expands, thus preventing overpressure that could damage the circuit. This specific model, with an 8-liter capacity and code 7819883, is designed for a 25 mm push-fit connection and dimensions of 390 mm diameter by 85 mm depth, ensuring perfect integration in compatible boilers.\u003c\/p\u003e\n\n\u003ch3\u003eWhat problem does this replacement part solve?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eExcessive pressure in the boiler due to the expansion of hot water.\u003c\/li\u003e\n\u003cli\u003eFrequent activation of the safety valve due to lack of pressure compensation.\u003c\/li\u003e\n\u003cli\u003eLeaks or noises in the hydraulic circuit caused by a defective or depleted expansion vessel.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eModels:\u003c\/h5\u003e\n\u003cp\u003eCompatible with various Viessmann boilers from the Vitopend and Vitodens series, ensuring optimal fit and safe operation.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eViessmann Vitopend 100-W HE4\u003c\/li\u003e\n\u003cli\u003eViessmann Vitopend WHK6\u003c\/li\u003e\n\u003cli\u003eViessmann Vitopend 100-W HE0\u003c\/li\u003e\n\u003cli\u003eViessmann Vitodens 200-W\u003c\/li\u003e\n\u003cli\u003eViessmann Vitodens 222-F\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFeatures:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003ePart type: hydraulic expansion vessel\u003c\/li\u003e\n\u003cli\u003eCompatible brand: Viessmann\u003c\/li\u003e\n\u003cli\u003eEquivalent codes: Viessmann 7819883, DGN 8\u003c\/li\u003e\n\u003cli\u003eVolume: 8 liters\u003c\/li\u003e\n\u003cli\u003eDimensions: diameter 390 mm x depth 85 mm\u003c\/li\u003e\n\u003cli\u003eConnection: 25 mm push-fit coupling\u003c\/li\u003e\n\u003cli\u003eCapacity to absorb thermal expansion in heating systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eRecommendation:\u003c\/h5\u003e\n\u003cp\u003eBefore purchasing, confirm that code 7819883 and your boiler model match this expansion vessel to ensure compatibility and avoid installation issues.\u003c\/p\u003e","brand":"VIESSMANN","offers":[{"title":"Default Title","offer_id":56664612209018,"sku":"REM-299900051","price":259.18,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/8026\/2676\/files\/7014951_151_sma.webp?v=1773878861","url":"https:\/\/electrotodo.uk\/products\/vaso-de-expansion-caldera-viessmann-8l","provider":"Electrotodo.es","version":"1.0","type":"link"}
