Technicus Barend Kloppenburg bedacht een retrofitoplossing die een traditionele convector actief laat ventileren. Kloppenburg schat dat dit concept toepasbaar is in ongeveer 135.000 bestaande woningen die nog moeten worden verduurzaamd, maar ziet ook kansen voor nieuwbouw vanwege de snelle reactietijd en lage kosten vergeleken met vloerverwarming. <\/strong><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><div id=\"pg-46743-1\"  class=\"panel-grid panel-no-style\" ><div id=\"pgc-46743-1-0\"  class=\"panel-grid-cell\" ><div id=\"panel-46743-1-0-0\" class=\"so-panel widget widget_sow-editor panel-first-child panel-last-child\" data-index=\"1\" ><div\n\t\t\t\n\t\t\tclass=\"so-widget-sow-editor so-widget-sow-editor-base\"\n\t\t\t\n\t\t><h3 class=\"widget-title\">Werking en ombouw: De 'convectorputsucker'<\/h3>\n<div class=\"siteorigin-widget-tinymce textwidget\">\n\t<p><span data-path-to-node=\"3,0\">Bij een traditionele put daalt koude lucht aan \u00e9\u00e9n zijde neer en stijgt op na opwarming<\/span><span data-path-to-node=\"3,2\">.
