In the energy-conscious world that we live in today, buildings built to be airtight are also becoming the norm. While they add insulation and reduce energy use, they also introduce a new problem: poor indoor air. Enter the heat recovery ventilation system, a remedy intended to deliver fresh air to homes more efficiently, without losing too much energy.Unlike mechanical ventilation systems that only allow air in and out, a heat recovery ventilation system uses the stale air expelled from the building to heat fresh air taken from outside. That is, in the winter, what is being expelled ultimately warms up the air entering the house (because it warms the air leaving it), and in the summer, the air being expelled ultimately makes the incoming warm air cooler. As such, your HVAC operates less to heat and cool your home, saving you money on utility bills.One of the greatest advantages of those ventilation systems is the enhancement of indoor air quality that they offer. That’s because modern homes can seal in pollutants, including dust, pet dander, cooking smells and VOCs from furniture or cleaning supplies. Combined with the fact that once installed, these filters can run for years in perfect condition, and that it’s all been designed in a way that won’t perpetuate them, so long to the allergies, asthma, and respiratory problems!Another big plus is the savings in energy. Working to minimize the amount of time heating and cooling systems need to kick on or off, they can help you save on your utility bill. And because they’re energy-efficient all year, you’ll save some money and help the environment over time. This goes on to make it a genial addition to the receptive house and the eco-friendly house designs.Control of humidity. Indoor air during heating months is dry, and during hotter seasons, there is too much humidity. A heat recovery ventilation system keeps moisture in check, leading to a healthier household environment and eliminating problems such as mould growth, dry skin and static electricity.Installation is fairly simple, especially on new builds, but it can also be installed on retrofits with professional help. It is simple to maintain, after installation, it simply requires cleaning of filters from time to time, and the occasional system check to ensure everything is running optimally.As code requirements for energy continue to tighten and consideration for indoor air quality becomes more prevalent, HRVs have shifted from being a luxury product to a building code requirement. It enables homeowners to experience the advantages of air-tight construction without the detriments of stale air and inconsistent temperatures.If you’d like a toasty, healthful, and efficient home, purchasing a heat recovery ventilation system is a no-brainer.David Williams is author of the article.
