Several factors can affect the coverage area of the heaters. Certain types of materials and grills distort the radiant waves.

Everyone has been stuck waiting hours for a table at one point or another. As the frustration grows, the number of customers leaving or standing in the waiting area without spending a dollar grows as well. Expanding a restaurant to include more chairs can be costly, but what if you could add chairs without completely extending or renovating your restaurant?\r\n\r\nRestaurant patios are growing increasingly popular in both the US and Canada with the COVID pandemic creating restrictions for indoor dining and the new trend in the enjoyment of eating in a beautiful outdoor atmosphere.\r\n\r\n<em>In a recent survey of consumer behavior conducted by Zagat\u2013 a majority, 77% of respondents said outdoor seating would make them more likely to dine in a restaurant.<\/em>\r\n\r\nRestaurant patios tend to attract customers to enjoy that outdoor dining experience and are a great way to increase seating opportunities. As the cooler temperatures arrive and new city guidelines are released to support fall and winter outdoor dining, there is a growing demand to keep customers warm and comfortable.\r\n\r\nRestaurant patio heaters are the solution to keep those outdoor diners warm and comfortable and are a great way to extend your patio season during the colder months and add more to your bottom line.\u00a0 If your outdoor restaurant patio isn\u2019t already heated, you are missing the opportunity to turn your tables and increase ROI.\r\n<h4>How to Extend your Restaurant Patio Season and Increase ROI<\/h4>\r\n<iframe src=\"https:\/\/www.youtube.com\/embed\/2p0G9GiBUY4?rel=0\" width=\"640\" height=\"360\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe>\r\n<h3>Let\u2019s Look at an Example<\/h3>\r\nInstalling a restaurant patio heating solution means you are able to extend your patio season by approximately 3 months and extend your patio operation by approximately 4 hours per day [this would account for the colder nights where customers would prefer to sit inside but do not have that flexibility due to the pandemic].\u00a0 Here\u2019s an example of how restaurant patio heaters can pay for themselves.\r\n\r\nRestaurant XYZ invests in patio heating to protect 10 tables on their patio during cooler temperatures. The 10 tables allow for seating of 40 patrons. It is anticipated the investment in overhead protection will extend the patio season by 10 weeks [3 months], adding 70 extra days of service per annum.\r\n\r\nThe average revenue at Restaurant XYZ is $20 per seat, and the tables turn over twice during dinner serving.\r\n\r\n<strong>Calculation:<\/strong>\r\n\r\nRevenue per extra seating $20 x 40 = $800\r\n\r\nTotal revenue per extra seating $56,000\u00a0 [($800 x 70 days = $56,000]\r\n\r\n[Example provided is based on industry figures and reports from the National Restaurant Association.]\r\n\r\nWith such a quick payback period and additional revenue generated each year, restaurant owners should really be asking themselves, can I afford not to have patio heaters installed on my patio?","_et_gb_content_width":"","footnotes":""},"categories":[320,328],"tags":[349,372,350],"location-tag":[],"class_list":["post-50727","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog","category-infrared-technology","tag-air-curtains","tag-schwank-one","tag-schwankair"],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/posts\/50727","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/users\/3377"}],"replies":[{"embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/comments?post=50727"}],"version-history":[{"count":1,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/posts\/50727\/revisions"}],"predecessor-version":[{"id":77180,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/posts\/50727\/revisions\/77180"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/media\/57208"}],"wp:attachment":[{"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/media?parent=50727"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/categories?post=50727"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/tags?post=50727"},{"taxonomy":"location-tag","embeddable":true,"href":"https:\/\/www.schwankgroup.com\/fr\/wp-json\/wp\/v2\/location-tag?post=50727"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
