Poor ventilation leads to moisture, CO\u2082 buildup, mold, and an uncomfortable indoor climate. That is precisely why heat recovery ventilators have become one of the most important devices in apartments, single-family homes, and buildings undergoing renovation.  <\/p>\n\n<p class=\"wp-block-paragraph\">But which heat recovery unit should you choose?<\/p>\n\n<p class=\"wp-block-paragraph\">There are many different manufacturers on the market, but in practice, the following often prove to be the most popular and reliable:<\/p>\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/proair.ee\/toode\/tippklassi-rekuperaator-blauberg-vento-inhome-w\/\">Blauberg<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/proair.ee\/toode\/ideal-clima-kers60-rekuperaator\/\">Ideal Clima KERS<\/a><\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">These devices stand out for their quiet operation, energy efficiency, reliability, and ease of use.<\/p>\n\n<h2 class=\"wp-block-heading\">What is a local heat recovery unit?<\/h2>\n\n<p class=\"wp-block-paragraph\">A local heat recovery unit, also known as a decentralized ventilation system, is a wall-mounted ventilation solution with heat recovery that does not require complex ductwork.<\/p>\n\n<p class=\"wp-block-paragraph\">It&#8217;s perfect for:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>into apartments<\/li>\n\n\n\n<li>in prefabricated apartment buildings<\/li>\n\n\n\n<li>older houses<\/li>\n\n\n\n<li>buildings undergoing renovation<\/li>\n\n\n\n<li>into the bedrooms<\/li>\n\n\n\n<li>home offices<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">Unlike a central ventilation system, installation is faster and significantly more affordable.<\/p>\n\n<p class=\"wp-block-paragraph\">Ventilation with heat recovery allows fresh air to be brought into a room without losing most of the heat. Modern systems can recover up to 95% of the heat. <\/p>\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n<h1 class=\"wp-block-heading\">Why are Blauberg heat recovery units

class=\"wp-block-paragraph\">7<\/p>\n\n<p class=\"wp-block-paragraph\">Blauberg is one of Europe&#8217;s best-known ventilation brands, and its VENTO series has earned a very strong reputation specifically in the field of local ventilation.<\/p>\n\n<p class=\"wp-block-paragraph\">Key benefits:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>very quiet operation<\/li>\n\n\n\n<li>high heat recovery<\/li>\n\n\n\n<li>high-quality EC motors<\/li>\n\n\n\n<li>Good Wi-Fi management<\/li>\n\n\n\n<li>humidity sensors<\/li>\n\n\n\n<li>elegant design<\/li>\n\n\n\n<li>low energy consumption<\/li>\n<\/ul>\n\n<p class=\"wp-block-paragraph\">The Blauberg VENTO series can achieve heat recovery efficiency of up to 95%.<\/p>\n\n<p class=\"wp-block-paragraph\">Some models operate at a noise level of only about 11\u201313 dB, which is practically a whisper.<\/p>\n\n<p class=\"wp-block-paragraph\">This makes them a very good choice:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>into

class=\"wp-block-heading\">Well-suited to the Estonian climate<\/h2>\n\n<p class=\"wp-block-paragraph\">A system with a ceramic heat exchanger works well even in cold weather and helps
