Another key requirement was that high-temperature hydraulic radiators could be used, to avoid the additional costs of a traditional gas installation.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">Group intuis (part of Glen Dimplex) provided a solution which was able to meet all of these requirements: an air source and centralized heat pump system.&nbsp;<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">The size of the system was determined using specialized software. A central heat pump system, integrated into the building, was selected. This has three monobloc units on the roof and a controller in the basement.&nbsp; Once the technical details had been approved, installation of the outdoor units, which had been specially adapted to fit discreetly on the roof, started in September 2021. This was followed by the installation of the indoor unit in the basement in February 2022.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">One of the main strengths of this system is the indoor control unit which can be used to manage the heating and hot water requirements together, and so avoids oversizing the installation. The domestic hot water and heating coupling is managed so that domestic hot water needs are prioritized before the system switches to space heating.<\/p>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"wp-block-paragraph \">There is an equal distribution of effort between the outdoor units. Operation is 100% thermodynamic down to -20\u00b0C, meaning there is no need for gas or direct electric back up. The very low noise level \u2013 at around 63 dB(A) &#8211; was also a factor in the customer\u2019s decision-making process.<\/p>\n<\/div>\n\n\n<div class=\"wp-block-group is-layout-constrained wp-block-group-is-layout-constrained\"><div class=\"container container--no-margin\">\n<div class=\"wp-block-buttons is-horizontal is-content-justification-center is-layout-flex wp-container-core-buttons-is-layout-b989473c wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button has-custom-width wp-block-button__width-50 has-custom-font-size is-style-outline has-medium-font-size is-style-outline--1\" style=\"text-transform:none\"><a class=\"wp-block-button__link has-vivid-cyan-blue-color has-white-background-color has-text-color has-background has-text-align-center wp-element-button\" href=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/01\/fact-sheet-glen-dimplex-sartrouville-france.pdf\" style=\"border-radius:5px\" target=\"_blank\" rel=\"noreferrer noopener\"><img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"84\" class=\"wp-image-2196\" style=\"width: 300px;\" src=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic.png\" alt=\"\" srcset=\"https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic.png 845w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-300x84.png 300w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-768x215.png 768w, https:\/\/heatpumpingtechnologies.org\/content\/uploads\/sites\/75\/2024\/02\/fact-sheet-button-pic-400x112.png 400w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/> <\/a><\/div>\n<\/div>\n<\/div>\n\n<div class=\"container container--no-margin\">\n<p class=\"has-text-align-center wp-block-paragraph \">FR002 Satrouville <\/p>\n<\/div><\/div>\n<\/div>\n\n\n<ol class=\"wp-block-footnotes\"><li id=\"56f4550a-92b4-49b4-ba3c-e242882597b9\">Pictures: ehpa &#8211; https:\/\/www.ehpa.org\/news-and-resources\/publications\/heat-pumps-and-high-rise-homes-case-studies-from-across-europe\/ <a href=\"#56f4550a-92b4-49b4-ba3c-e242882597b9-link\" aria-label=\"Jump to footnote reference 1\">\u21a9\ufe0e<\/a><\/li><\/ol><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sartrouville This pilot project became a textbook solution which has been replicated with regard to French Building Codes RE2020 and&#8230;<\/p>\n","protected":false},"author":41,"featured_media":0,"menu_order":0,"template":"","filters":[],"markets":[23],"applications":[7,41],"class_list":["post-2239","case_studies","type-case_studies","status-publish","hentry","markets-france","applications-buildings","applications-multi-family-buildings"],"acf":[],"_links":{"self":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2239","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies"}],"about":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/types\/case_studies"}],"author":[{"embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/users\/41"}],"version-history":[{"count":4,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2239\/revisions"}],"predecessor-version":[{"id":2284,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/case_studies\/2239\/revisions\/2284"}],"wp:attachment":[{"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/media?parent=2239"}],"wp:term":[{"taxonomy":"filters","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/filters?post=2239"},{"taxonomy":"markets","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/markets?post=2239"},{"taxonomy":"applications","embeddable":true,"href":"https:\/\/heatpumpingtechnologies.org\/project62\/wp-json\/wp\/v2\/applications?post=2239"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
