The corrosion-resistant stainless steel Inox-Radial heat exchanger with unrivalled wall thickness, is extremely durable and achieves efficiency levels of up to 97%. The boiler's special design ensures the very low operating noise of 39 dB(A) maximum (26 kW), which is perfectly acceptable even in the kitchen. The Vitodens 100-W Open vent can even operate in weather compensated mode without incurring a costly heating system modification, all that is needed is a simple upgrade. Weather compensation acts like an autopilot as it detects outside temperature changes and automatically adjusts the flow temperature of the boiler, achieving gas savings of up to 12% in the process. All of which add up to an incredibly reliable, but quiet and efficient system.\u003cbr data-mce-fragment=\"1\"\u003e\u003cbr data-mce-fragment=\"1\"\u003e\n\u003cul\u003e\n\u003cli\u003eSEDBUK Band 'A' rated fuel efficiency\u003c\/li\u003e\n\u003cli\u003eCompact dimensions to fit in standard kitchen cupboards\u003c\/li\u003e\n\u003cli\u003eUser friendly control via backlit touchscreen\u003c\/li\u003e\n\u003cli\u003eStandard efficiency up to 97% through stainless steel Inox-Radial heat exchanger\u003c\/li\u003e\n\u003cli\u003eModulation range up to 1:6\u003c\/li\u003e\n\u003cli\u003eModulating cylinder burner\u003c\/li\u003e\n\u003cli\u003eWeather compensation option\u003c\/li\u003e\n\u003cli\u003eLPG conversion available\u003c\/li\u003e\n\u003cli\u003eLarge user display\u003c\/li\u003e\n\u003cli\u003eStandard 5 year Warranty\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Viessmann","offers":[{"title":"Default Title","offer_id":39581496082618,"sku":"CPLUMB(311473)","price":6065.95,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0528\/2149\/1898\/products\/GPID_1000560870_IMG_00.jpg?v=1620647006","url":"https:\/\/www.supplieddirect.co.uk\/products\/viessmann-vitodens-100-w-35kw-heat-only-boiler-wb1b491","provider":"Supplieddirect.co.uk","version":"1.0","type":"link"}
