The system based on heat pumps with a supply of about 2,2 MW to the DH network of the City, depending on the temperature and the mass flow of the source. The heat pumps are designed to get a maximum output temperature of 84 \u00b0C. An additional electrical boiler of 375 kW thermal energy increases the temperature up to 90 \u00b0C if the outdoor temperature is below -5 \u00b0C. Yearly produced heat amounts to around 11 GWh.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \"><\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \"><a href=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/69\/2024\/12\/two-pager-task-2-austria-thermewien-waste-heat-utilization-spa-wiennapdated.pdf\">Two page summary<\/a><br><br><a href=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/69\/2024\/12\/annex57-task-2-austria-thermewien-waste-heat-utilization-spa-wienna.pdf\">Full report <\/a><\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \"><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>Vienna, Austria The overall system was developed to utilise the waste heat of the thermal (waste)water of \u201cSpa Vienna\u201d located&#8230;<\/p>\n","protected":false},"author":61,"featured_media":0,"menu_order":0,"template":"","filters":[82,92,95],"markets":[14],"applications":[42,39],"class_list":["post-721","case_studies","type-case_studies","status-publish","hentry","filters-austria","filters-central-hp-and-dh","filters-in-operation","markets-austria","applications-cities-communities","applications-system-integration-flexibility"],"acf":[],"_links":{"self":[{"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/case_studies\/721","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/case_studies"}],"about":[{"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/types\/case_studies"}],"author":[{"embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/users\/61"}],"version-history":[{"count":2,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/case_studies\/721\/revisions"}],"predecessor-version":[{"id":725,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/case_studies\/721\/revisions\/725"}],"wp:attachment":[{"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/media?parent=721"}],"wp:term":[{"taxonomy":"filters","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/filters?post=721"},{"taxonomy":"markets","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/markets?post=721"},{"taxonomy":"applications","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project57\/wp-json\/wp\/v2\/applications?post=721"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
