The project was supervised by Pawe\u0142 R\u0119dzi\u0144ski, MSc Eng., who acted as the site manager and holds execution licenses in the field of building services.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a result, the entire process, from design and installation to commissioning and balancing, was carried out under the supervision of suitably qualified professionals. During the design stage, attention was given to the layout and floor area of each dwelling, required airflow rates, terminal locations and duct routing. Also ventilation unit placement, service accessibility, acoustic comfort and overall energy efficiency was important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The repetitive layout of the buildings made it possible to develop proven solutions that could be applied consistently throughout the development while maintaining installation quality.<\/p>\n\n\n<section class=\"mb-8 w-full FiftyFiftyVisualWrapper\"  >\n    <div>\n        <div class=\"FiftyFiftyVisual relative flex w-full justify-between flex-col xl:flex-row\">\n            <div class=\"h-min\n                w-full xl:w-5\/12 3xl:w-7\/12\n                pt-4 sm:pt-8 md:pt-12 lg:pt-20  3xl:pt-20\n                px-0\n                \n            \">\n                <div class=\"bgElement calc(100vw \/ 2 * ((100vw - 1860px) * 0.1))\n                    absolute z-0 reversewrap\n                    bgElement-right\n                    left-0 right-0 xl:right-[50%] 3xl:right-[calc((40vw-((100vw-1860px)*-0.03)))] 3xl:min-w-[1200px] xl:rounded-tr-xl\n                    \n                    top-0\n                    bottom-24 xl:bottom-0\n                                        bg-[rgba(165,185,196,0.3)]\"\n                ><\/div>\n                                    <h2 class=\"Title Title-left relative z-10\n                        flex flex-col justify-start\n                        text-black\n                        text-2xl lg:text-3xl 2xl:text-4xl\n                        leading-7 lg:leading-8\n                        font-bold\n                        mb-4\n                        xl:pr-8\n                        \">\n                        Why choose MyVallox 119 CFi?

The system needed to also provide individual control for residents, consume little electrical energy and allow easy access for maintenance and filter replacement.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, the solution needed to comply with the design documentation and applicable technical requirements while remaining suitable for repeated use across similar dwelling layouts.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Coordinating the Installation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the main challenges was coordinating the ventilation installation with other building services, structural elements, and interior finishes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As is typical in residential construction, the available space for ductwork was limited, requiring careful planning of duct routes and ventilation unit locations. Ensuring suitable access for servicing the units and replacing filters was also an important consideration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These challenges were addressed through ongoing coordination between different trades, supervision by a qualified professional, on-site verification of solutions, and the standardization of installation methods across repetitive dwelling layouts.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After installation, every system was commissioned, inspected, measured and balanced according to the design of airflow values.<\/p>\n\n\n<div  class=\"Image w-full h-auto mb-8\">\n    <img decoding=\"async\"\n        srcset=\"\n            https:\/\/www.vallox.com\/app\/uploads\/2026\/08\/6Styled-50-50-element-1024x577.webp 1024w,\n            https:\/\/www.vallox.com\/app\/uploads\/2026\/08\/6Styled-50-50-element-768x433.webp 768w,\n            https:\/\/www.vallox.com\/app\/uploads\/2026\/08\/6Styled-50-50-element-300x169.webp 300w,\n            https:\/\/www.vallox.com\/app\/uploads\/2026\/08\/6Styled-50-50-element-150x150.webp 150w,\n        \"\n        alt=\"Asennuksen j\u00e4lkeen jokainen j\u00e4rjestelm\u00e4 otettiin k\u00e4ytt\u00f6\u00f6n, tarkastettiin, mitattiin ja tasapainotettiin suunniteltujen ilmavirta-arvojen mukaisesti\"\n        src=\"https:\/\/www.vallox.com\/app\/uploads\/2026\/08\/6Styled-50-50-element-300x169.webp\"\n        class=\"object-cover w-full h-auto\"\n    \/>\n            <div class=\"ImageTexts\">\n                            <div class=\"Caption italic\">\n                    MyVallox 119 CFi automatically compensates for pressure differences and maintains airflow rates at the designed level.\n                <\/div>\n            \n                    <\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Resident Feedback has been positive<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Klimat Dom reports positive feedback regarding both indoor air comfort and the everyday operation of the systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">According to them, residents particularly appreciate the constant supply of fresh air without the need to open windows regularly. Residents also appreciate effective removal of moisture from bathrooms and odors from living spaces, and the ability to adjust ventilation rates according to their individual needs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Once correctly installed and balanced, the systems operate automatically and require only regular inspection and replacement of filters.<\/p>\n\n\n<section class=\"mb-8 w-full FiftyFiftyVisualWrapper\"  >\n    <div>\n        <div class=\"FiftyFiftyVisual relative flex w-full justify-between flex-col xl:flex-row-reverse\">\n            <div class=\"h-min\n                w-full xl:w-5\/12 3xl:w-7\/12\n                pt-4 sm:pt-8 md:pt-12 lg:pt-20  3xl:pt-20\n                px-0\n                pl-8\n            \">\n                <div class=\"bgElement calc(100vw \/ 2 * ((100vw - 1860px) * 0.1))\n                    absolute z-0 reversewrap\n                    bgElement-left\n                    \n                    right-0 left-0 xl:left-[50%] 3xl:left-[calc((40vw+((100vw-1860px)*0.07)))] 3xl:min-w-[1200px] xl:rounded-tl-xl\n                    top-0\n                    bottom-24 xl:bottom-0\n                                        bg-[rgba(165,185,196,0.3)]\"\n                ><\/div>\n                                    <h2 class=\"Title Title-right relative z-10\n                        flex flex-col justify-start\n                        text-black\n                        text-2xl lg:text-3xl 2xl:text-4xl\n                        leading-7 lg:leading-8\n                        font-bold\n                        mb-4\n                        \n                        xl:pl-8\">\n                        A Solution They Would Choose Again \n                    <\/h2>\n                                                    <div class=\"Content Content-right flex flex-col justify-center relative z-10\n                        \n                        xl:pl-8\">\n                                                    <span class=\"Text text-black xl:text-custom-gray-dark pb-2\">\n                                <p>Klimat Dom rates the quality of the Vallox 119 CFi units very highly.
