Energy recovery ventilator improves energy efficiency and air quality in tightly sealed home
Because of the weather extremes in the area where I live, it’s necessary to tightly seal the home. I’ve taken the time to carefully caulk around windows and doors, added weatherstripping and upgraded insulation in walls and ceilings. I’ve done everything possible to prevent my heated and cooled air from leaking outside. While my efforts have made my home more comfortable and saved money on energy bills, I’ve eliminated essential ventilation. After consulting with a local HVAC contractor, I invested in an energy recovery ventilator. This type of ventilation system is a practical and efficient solution to issues with indoor air quality. The energy recovery ventilator installed into my attic and provides improvement throughout the entire house. It pulls fresh, clean air in from outdoors, while venting out stale air from inside the home. It transfers a significant amount of energy from the outgoing air into the fresh air that is brought inside. During the winter, the ventilator heats the incoming air. In the summer months, it helps cool the incoming air. By reusing this energy, it reduces the workload of the furnace and air conditioner, saving me money. The ventilator works by passing the streams of incoming and outgoing air through a heat exchanger. The air streams do not mix, but heat energy is transferred as needed. The constant supply of fresh outdoor air replaces the stale air inside the home, creating a cleaner and healthier environment. Contaminants and allergens such as dust, dander, pollen, and even bad odors are vented outside. Plus the energy recovery ventilator helps with humidity control all year round. It transfers moisture to and from incoming air to maintain superior relative humidity levels.
