The natural air exchange typical of older buildings is deliberately prevented by the use of modern insulation materials. As a result, CO\u2082, water vapor, and other substances are no longer continuously removed.<\/p>\n<p>In particular, the burden of moisture released during breathing steadily increases. An average family of three releases around 10 liters of moisture into the environment each day in this way. If the supply of fresh air is insufficient, rot and mold growth can result.<\/p>\n<p>To maintain a healthy indoor climate, regular cross ventilation is therefore necessary and advisable in frequently used rooms. However, the classic method of ventilating rooms by frequently opening windows is difficult to reconcile with the desire for high energy efficiency.<\/p>\n<p>Especially during the colder months, you can significantly reduce your heating costs with a residential ventilation system.<\/p>\n<p>Our WAC Westa Air Control achieves a thermal efficiency of up to 94%, as outside air, supply air, exhaust air, and stale air are all routed through a cross-counterflow heat exchanger.<\/p>\n<p>Air quality improves considerably because pollen, exhaust fumes, and fine dust are filtered out.<\/p>\n<\/div><\/section><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":4,"featured_media":8999,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"tags":[],"portfolio_entries":[],"class_list":["post-9000","portfolio","type-portfolio","status-publish","has-post-thumbnail","hentry"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
