Harvia sauna stones provide good and soft heat. Split-face sauna stones are the only correct stones for electric heaters and woodburning stoves because they can store lots of heat and the water evaporates efficiently from the wide surface of the fracture. Angular split-face stones also allow for loose placement of the stones, which is the most important requirement, particularly in electric heaters in order to make it possible for the heat to be conveyed to the sauna room between the hot stones and heating elements. Good air circulation in the stone space makes the electric heating elements last for as long as possible.\u003c\/p\u003e\u003cp\u003eThe AC3020 stones work for the following Harvia Sauna Heaters-\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eVirta Series\u003c\/li\u003e\n\u003cli\u003eAF (Forte) Series\u003c\/li\u003e\n\u003cli\u003eM Series\u003c\/li\u003e\n\u003cli\u003ePro Series\u003c\/li\u003e\n\u003cli\u003eLegend Series\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eCAUTION\u003c\/strong\u003e: Light (ceramic), soft (soapstone), and smooth (rounded) sauna stones do not produce the desired results and they may cause problems in electric heaters in particular. \u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eTraditional angular olivine diabase sauna stones mined from subvolcanic rock in Western Finland.\u003c\/li\u003e\n\u003cli\u003eDurable split-face design stores plenty of heat, making water vaporize efficiently when splashed on the broad surface.\u003c\/li\u003e\n\u003cli\u003eEasy to stack with good air circulation and high thermal conductivity for heaters with active use.\u003c\/li\u003e\n\u003cli\u003eCompatible with large electric heaters and wood-burning sauna stoves.\u003c\/li\u003e\n\u003cli\u003eDoes not contain harmful ingredients.\u003c\/li\u003e\n\u003cli\u003eStones range from 4-6\" (10-15 cm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eIncludes\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e44 lb box of 4\" to 6\" (10-15 cm) Split-Face Sauna Stones\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eAC3020\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eGrey\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShape\u003c\/td\u003e\n\u003ctd\u003eSplit-Face\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eOlivine Diabase\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStone Size\u003c\/td\u003e\n\u003ctd\u003e4-6\" (10-15 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e44.1 lbs (20 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Width\u003c\/td\u003e\n\u003ctd\u003e11.4 \" (29 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Depth\u003c\/td\u003e\n\u003ctd\u003e15.8\" (40.1 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Height\u003c\/td\u003e\n\u003ctd\u003e5.9\" (15 cm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e44.5 lbs (20.2 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003ch3\u003eTechnical\u003c\/h3\u003e\u003ch3\u003eHarvia Stone Requirements\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/americansaunaco.com\/cdn\/shop\/files\/Harvia-Stone-Requirements-2026-09-25.pdf?v=1\"\u003eHarvia Stone Requirements 9.25.26.pdf\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eCertification\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003ca href=\"https:\/\/americansaunaco.com\/cdn\/shop\/files\/Harvia-Olivine-Diabase-Sauna-Stone-Certificate.pdf?v=1\"\u003eHarvia-Olivine-Diabase-Sauna-Stone-Certificate.pdf\u003c\/a\u003e\u003c\/li\u003e\u003c\/ul\u003e","brand":"Harvia","offers":[{"title":"Default Title","offer_id":63375920758865,"sku":"104-AC3020","price":62.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0998\/3220\/1297\/files\/harvia-sauna-stones-split-face-AC3020_87969406-a19d-419a-ae72-46f1279ee9dc.jpg?v=1793625435"},{"product_id":"harvia-ac3040","title":"Harvia AC3040","description":"\u003ch3\u003eDescription\u003c\/h3\u003e\u003cp\u003eThe durable Harvia AC3040 is a vulcanite sauna stone designed to perform at fluctuating temperatures with maximum efficiency.\u003c\/p\u003e\u003cp\u003eWith volcanic origins dating back millions of years, the fine-grained dark grey sauna stones shine black when wet for a beautiful, versatile look to compliment any sauna interior.
