When heated, they cause small explosions that make the stones split and break off small pieces, creating sharp edges that can damage the heater's heating elements.\u003cbr\u003e\u003cbr\u003eIt can happen that the uneven shapes push the heating elements around and deform them. The uneven shapes and sizes make it a bit of a \"puzzle\" to install them in an electric heater, as they constantly need to be assessed, turned, and rotated to fit between the heating elements, which wastes time.\u003cbr\u003e\u003cbr\u003eAlready after the 1st heating, they lose approx. 5% of their weight and then approx. 1-2% per heating, so after approx. 100 heatings, they are as light as pumice stones.\u003cbr\u003e\u003cbr\u003eBefore being placed in the heater, they must be washed clean of stone dust, which has arisen because the stones rub against each other. This also happens during use, where the stone dust spreads in the sauna room.\u003cbr\u003e\u003cbr\u003eIn this way, they cannot accumulate heat, which results in longer operating time for the heating elements, faster cooling during sauna infusions, and thus greater electricity consumption. At the same time, the discarded edges rattle down to the bottom of the heater as gravel and small stones, which in unfortunate cases can lead to short circuits or earth faults that can black out the entire group to which the sauna heater is connected.\u003cp style=\"text-align: left;\" align=\"center\"\u003e\u003cspan style=\"color: #000000; font-size: large;\"\u003eThis is what the hard-fired ceramic stones from Kerkes look like 1 year after replacement!\u003c\/span\u003e\u003c\/p\u003e\u003cp style=\"text-align: left;\" align=\"center\"\u003e\u003cimg class=\"alignnone size-medium wp-image-22509\" src=\"https:\/\/www.gusmester.dk\/wp-content\/uploads\/2020\/05\/kerkes-saunasten-2-300x168.jpeg\" alt=\"\" width=\"300\" height=\"168\"\u003e\u003c\/p\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHow to install the stones in Tylö heaters:\u003c\/strong\u003e\u003cul\u003e\n\u003cli\u003eFirst, the spherical stones are placed between the heating elements; the 60 mm diameter fits perfectly with the curve of the heating elements.\u003cbr\u003e\u003cimg class=\"alignnone wp-image-14048 size-full\" src=\"https:\/\/www.gusmester.dk\/wp-content\/uploads\/2020\/05\/kuglesten-montering-tyloe.jpg\" alt=\"\" width=\"374\" height=\"232\"\u003e\n\n\u003c\/li\u003e\n\u003cli\u003eThen the large tetra stones are placed on top of the spherical stones.\u003c\/li\u003e\n\u003cli\u003eAfter that, the small tetra stones are placed at the top.\u003c\/li\u003e\n\u003cli\u003eThis way, a large surface area is achieved, which can evaporate the sauna infusion water faster.\u003c\/li\u003e\n\u003cli\u003e\u003cimg class=\"alignnone wp-image-14049 size-full\" src=\"https:\/\/www.gusmester.dk\/wp-content\/uploads\/2020\/05\/tetrasten-montering-tyloe.jpg\" alt=\"\" width=\"372\" height=\"234\"\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ca href=\"https:\/\/gusmester.dk\/wp-content\/uploads\/2021\/02\/Kerkes-saunasten-brugermanual.pdf\" target=\"_blank\" rel=\"noopener\"\u003eRead or download the \"Kerkes-saunasten-brugermanual\" here...\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003e\u003cbr\u003eWhat are the different stone types used for?\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eIntermediate stones\u003c\/strong\u003e: For electric sauna heaters without a separate stone chamber.\u003cbr\u003ePlaced between the rows of heating elements in a thickness that matches the distance between the rows of heating elements.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpherical stones\u003c\/strong\u003e: For electric sauna heaters with a separate stone chamber and wood-fired heaters.
