Comforting Warmth
Infrared radiators are being used more often to warm restaurant terraces. Lately they are increasingly being equipped with NEXTREMA® glass-ceramic front panels from SCHOTT.

For Frank Buchholz, we have long become part of a fresh air generation. This development can also be attributed to increasingly warm summers. ”People enjoy sitting outside for as long as possible,” says the chef, who opened a gourmet restaurant in Mainz more than ten years ago and has been running the restaurant Das Bootshaus on the shore of the harbor in Mainz since 2011. Many people who are out taking a walk stop by Das Bootshaus, where they can enjoy culinary delights while sitting at sturdy wooden tables. Frank Buchholz sticks to down-to-earth home cooking and uses only products from regional suppliers from Mainz, catfish and walleye from the Rhine that local fishermen bring to him on a regular basis, for example.

He finally found a solution he liked from MHS Munich Home Systems GmbH, a manufacturer based in Munich, Germany, and purchased his first Heatscope® brand infrared radiator, still a prototype at the time. ”In my kitchen, I place high demands on the products I use. I have the same high standards on choosing my amenities and furniture,” says Buchholz. The design also has to be just right and, last, but not least, I am an environmentally conscious person.” In the meantime, Heatscope® infrared radiators are available in three different versions. One of them is equipped with a NEXTREMA® glass-ceramic front. ”Our high-performance glass-ceramic allows the heat to pass through nearly without any losses and reduces the visible light output,” says Andy Rinaldi, Product Manager at SCHOTT, in explaining the benefits NEXTREMA® offers.

Whether it’s in the bathroom (right) or the catering industry (above), NEXTREMA® is used as a cover for Heatscope® infrared heaters in many different areas. Whereas conventional radiant heaters often emit strong light, a translucent or tinted NEXTREMA® cover lens transforms the glare of the heating elements into a pleasant glow with virtually no heat loss.

”We offer so many benefits, such as energy efficiency, ease of cleaning or the transparency of the glass-ceramic for use in LED lighting, for example. You can easily see from the outside whether the spotlight is on or off,”
says Rinaldi. The close cooperation between SCHOTT and MHS Munich Home Systems GmbH extends even further. ”We assist our customer in choosing the right material when it comes to the next product generation or new fields of application,” says Rinaldi.
