Why We Need a Ventilation System and How to Choose the Best Home Heat Recovery UnitWhen it comes to creating a comfortable living environment, most people think about heating and cooling systems. However, one of the most important components of a healthy home is often overlooked – ventilation. A proper ventilation system is essential for maintaining indoor air quality and reducing the risk of health problems caused by poor air circulation.In today's tight and energy-efficient homes, mechanically controlled ventilation systems have become the norm. One of the most popular and effective types of mechanical ventilation is the MVHR system – Mechanical Ventilation with Heat Recovery. In this article, we will explain why we need a ventilation system, how an MVHR unit works, and provide you with information on choosing the best home heat recovery unit.Why We Need a Ventilation System?Indoor air quality is fundamental to our health and wellbeing. Indoor air pollutants such as volatile organic compounds (VOCs), carbon monoxide, nitrogen dioxide, and fine particulate matter can lead to various health issues, including allergies, asthma, respiratory infections, and even cancer.In addition to reducing indoor air pollutants, proper ventilation is necessary for reducing high humidity, which can lead to mold growth, and for replacing stale air with fresh, oxygenated air.A ventilation system works by controlling the air exchange between indoor and outdoor environments, ensuring that fresh air is delivered to living spaces while stale air is extracted. By doing so, a proper ventilation system can maintain healthy indoor air quality, prevent the development of mold, and make your living space more comfortable.What is an MVHR Unit?An MVHR unit is a type of mechanical ventilation system that uses ducts to circulate air throughout your home. The system is designed to extract stale air from inside your living space and replace it with fresh air from outside while recovering up to 95% of the heat from the extracted air.The MVHR unit consists of two interconnected duct systems – one for extracting stale air from inside your home, and another for supplying fresh air from outside. As the extracted air passes through the heat exchanger, it transfers its heat to the incoming fresh air, reducing the amount of heat needed to warm the air in your home.Because the MVHR system works efficiently to recover heat from stale air, it can help reduce heating costs in the winter and also reduce cooling costs in the summer since it allows fresh air to be automatically exchanged while recovering the cool air you want to pump back in.Choosing the Right MVHR UnitWhen it comes to choosing the right MVHR unit for your home, several factors need consideration. First and foremost is the size of the unit, which is determined by the size of your living space and the number of rooms you want to ventilate. Most manufacturers offer MVHR systems that are suitable for single or multi-room installations.The next important factor to consider is the efficiency of the system. Look for an MVHR unit with a high heat recovery rate (up to 95%) as this will help you save on heating costs in the long run. It is also important to consider the noise level of the system since a noisy system can cause annoyance and discomfort.Lastly, choose a reputable brand that follows industry standards and regulations. This will ensure that your MVHR unit operates safely and efficiently with a long-term warranty, protecting your investment for several years to come.ConclusionMaintaining healthy indoor air quality is critical for our general well-being. A proper ventilation system can help reduce indoor air pollutants while maintaining a comfortable living environment. The MVHR unit is an effective and efficient mechanical ventilation system that recovers up to 95% of heat from the extracted stale air. By investing in a quality MVHR unit with a high heat recovery rate, low noise levels, and proven brand, you can ensure that your home has the best ventilation system available.
