Its main function is to absorb the volume variations of the water as it heats up, thus preventing excessive pressure increases that could damage the hydraulic circuit. This Viessmann expansion vessel model 7828646 is designed to maintain stable pressure and protect the boiler from possible leaks or internal damage.\u003c\/p\u003e\n\n\u003ch3\u003eWhat problem does this replacement part solve?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUnstable or excessive pressure in the heating circuit.\u003c\/li\u003e\n\u003cli\u003eWater loss due to leaks caused by overpressure.\u003c\/li\u003e\n\u003cli\u003eMalfunction or failure of the boiler due to unbuffered water expansion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eModels:\u003c\/h5\u003e\n\u003cp\u003eCompatible with Viessmann boilers from the Vitopend series and related models that use the expansion vessel with code 7828646.\u003c\/p\u003e\n\u003ctable\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eViessmann Vitopend 100 WB1B\u003c\/td\u003e\n    \u003ctd\u003eViessmann Vitopend 100 WH1B\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eViessmann Vitopend 111 WH1B\u003c\/td\u003e\n    \u003ctd\u003eViessmann Vitopend 200\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eViessmann Vitodens 100-W\u003c\/td\u003e\n    \u003ctd\u003eViessmann Vitodens 111-W\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd\u003eViessmann Vitodens 200-W\u003c\/td\u003e\n    \u003ctd\u003eViessmann Vitopend 222-W\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch5\u003eFeatures:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003ePart type: expansion vessel for boiler\u003c\/li\u003e\n\u003cli\u003eCompatible brand: Viessmann\u003c\/li\u003e\n\u003cli\u003eCodes: 7828646 (Viessmann)\u003c\/li\u003e\n\u003cli\u003eCapacity: 8 liters\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure: 3 bar\u003c\/li\u003e\n\u003cli\u003eApproximate dimensions: 100 mm (diameter) x 340 mm (height) x 300 mm (depth)\u003c\/li\u003e\n\u003cli\u003eConnection thread: 13 mm (3\/8\")\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eRecommendation:\u003c\/h5\u003e\n\u003cp\u003eBefore purchasing, verify that code 7828646 matches your current expansion vessel or that your Viessmann boiler model is among the compatible ones to ensure a perfect fit and avoid returns.\u003c\/p\u003e","brand":"VIESSMANN","offers":[{"title":"Default Title","offer_id":56664612143482,"sku":"REM-299900046","price":246.45,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/8026\/2676\/files\/7008295_232_sma.webp?v=1773878841","url":"https:\/\/electrotodo.com\/products\/vaso-expansion-caldera-viessmann-7828646","provider":"Electrotodo.es","version":"1.0","type":"link"}
