The old extraction heat pump had reached the end of its technical lifespan, in addition to which it was too small for the 176 square metre house.<\/p>\n\n\n\n<p>-Due to this under-dimensioning, the unit was on constantly in very cold weather and also used electricity to supplement the heating. It was time to start thinking about replacing the system in order to cut down the energy consumption.<\/p>\n\n\n\n<p>Airaksela decided to replace the old extraction air pump with an <a href=\"https:\/\/www.vallox.com\/en\/product\/vallox-110-mv\/\" target=\"_blank\" rel=\"noreferrer noopener\">air-to-water heat pump by Viessmann<\/a> and the <a href=\"https:\/\/vallox.com\/product\/vallox-110-mv\/?lang=en\" target=\"_blank\" rel=\"noreferrer noopener\">Vallox 110 MV ventilation unit<\/a>. With the new combination, the heating and ventilation of the building are implemented cost-effectively.<\/p>\n\n\n\n<p>-The efficiency of the old unit was only around 30%, whist the efficiency of the new system is around 90%. The figures show that it was about time both the heating and the ventilation systems were upgraded.<\/p>\n\n\n\n<p>In addition to energy savings, Airaksela appreciates good, effective, and reliable ventilation, which contributes to the comfort of living.<\/p>\n\n\n\n<p>-The indoor air is probably the most important aspect of housing, and it can only be achieved through controlled mechanical ventilation. The filtering of the supply air is very important and the filters of the Vallox units are very effective. They do not let pollen inside the apartment in the spring.<\/p>\n\n\n\n    <div  class=\"Video w-full h-auto mx-auto \" style=\"\">\n        \n                            <iframe class=\"w-full h-auto aspect-video\" src=\"https:\/\/www.youtube-nocookie.com\/embed\/E9u2I06a_aE\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n            \n            <\/div>\n\n\n\n<p><\/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\/2023\/07\/Airaksela_kuva1-1024x683.jpg 1024w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva1-768x512.jpg 768w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva1-300x200.jpg 300w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva1-150x150.jpg 150w,\n        \"\n        alt=\"The initial situation before the energy renovation and the new Vallox 110 MV unit\"\n        src=\"https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva1-300x200.jpg\"\n        class=\"object-cover w-full h-auto\"\n    \/>\n            <div class=\"ImageTexts\">\n            \n                            <div class=\"Description\">\n                    LEFT: The initial situation before the energy renovation. The old extraction air pump was removed to make room for the new heating and ventilation system. RIGHT: The old extraction heat pump, located in the technical space, was replaced with a Vallox 110 MV ventilation unit. The air-to-water heat pump was mounted on the adjacent wall.\n                <\/div>\n                    <\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">The decision to choose Vallox was easy to make<\/h2>\n\n\n\n<p>Airaksela did not select a Vallox ventilation unit at random. As a former CEO of <a href=\"https:\/\/www.arkta.fi\/\" target=\"_blank\" rel=\"noreferrer noopener\">Arkta Reponen<\/a>, a construction firm, he got familiar with the offering and the options of building technology through his work. He considers Vallox ventilation products to be the best in the market as regards their energy consumption and other features.<\/p>\n\n\n\n<p>-When working at Arkta, we purchased roughly 300 apartment-specific ventilation units each year and Vallox was selected to our sole partner. This is due to the fact that Vallox units are, simply, the best in the world.<\/p>\n\n\n\n<p>It was for this reason that Airaksela also chose a Vallox ventilation system for his own home. The features that Airaksela appreciates in the Vallox units include energy-efficiency, controlling, and integrated automatics. The integrated carbon dioxide and humidity sensors of the Vallox units boost the ventilation automatically based on the need, which contributes to flexible and care-free apartment-specific ventilation.<\/p>\n\n\n\n<p>The units can be taken into use immediately after installation. In addition, we had remote control in all buildings built by Arkta, which allows us to see the status of the ventilation at all times. In addition, history data is always saved when the unit is used remotely.<\/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\/2023\/07\/Airaksela_kuva2-1024x683.jpg 1024w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva2-768x512.jpg 768w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva2-300x200.jpg 300w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva2-150x150.jpg 150w,\n        \"\n        alt=\"The MyVallox control panel close to the front door\"\n        src=\"https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva2-300x200.jpg\"\n        class=\"object-cover w-full h-auto\"\n    \/>\n            <div class=\"ImageTexts\">\n            \n                            <div class=\"Description\">\n                    The MyVallox control panel was moved close to the front door to make it easy to use. However, little attention needs to be paid to ventilation by the residents, as it is controlled automatically.\n                <\/div>\n                    <\/div>\n    <\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Energy is saved when the consumption reduces<\/h2>\n\n\n\n<p>Before the renovation, Airaksela\u2019s detached house consumed roughly 24,000 &#8211; 25,000 kWh of energy &#8211; all electricity included. The energy-efficiency of the new system is based on the excellent annual efficiency of the ventilation and the COP value (Coefficient Of Performance) of the air-to-water heat pump. The COP value describes how efficiently the consumed electricity is transformed into heating energy. The annual efficiency of ventilation, on the other hand, tells how much heat the heat recovery system can recover from the extract air in order to heat the supply air on average throughout the year. Based on Airaksela\u2019s estimation, the energy renovation reduces the consumption by half.<\/p>\n\n\n\n<p>-I wanted a more sensible and cost-efficient solution and, because I have studied energy matters also as part of my work, this was the best solution. Thanks to a good efficiency ratio, the units can produce all the heat and water we need.<\/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\/2023\/07\/Airaksela_kuva3-1024x683.jpg 1024w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva3-768x512.jpg 768w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva3-300x200.jpg 300w,\n            https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva3-150x150.jpg 150w,\n        \"\n        alt=\"Airaksela\u00b4s detached house\"\n        src=\"https:\/\/www.vallox.com\/app\/uploads\/2023\/07\/Airaksela_kuva3-300x200.jpg\"\n        class=\"object-cover w-full h-auto\"\n    \/>\n            <div class=\"ImageTexts\">\n            \n                            <div class=\"Description\">\n                    \nBefore the renovation, Airaksela\u2019s 176 square metre detached house consumed roughly 24,000 &#8211; 25,000 kWh of energy a year.
