Fresh Indoor Air Without Losing Heat
There are very few of us in the north that aren’t worrying about oil prices this winter. People weatherized like crazy this last fall in preparation for the cold weather, and others are considering added insulation. But energy efficient homes can come with a serious price: Less healthy indoor air. When there isn’t enough fresh air flow and health promoting negatives ions entering the home, people get sick. Worse, the pollutants such as cleaning materials aren’t cleared from the indoor air.
It is hard to imagine ensuring that your home has fresh air by opening a window every day, especially when you hear the oil burner cranking away to compensate! Here is great way to solve this problem: A simple mechanical system that does this for you. It will remove polluted air and replace it with fresh, filtered outdoor air. It is an energy recovery ventilator (ERV), and this is how it works.
In the winter the ERV uses warm outgoing air to heat the incoming cooler air, as well as leaving a comfortable and healthy amount of humidity inside (the incoming and outgoing air have separate compartments so that pollutants are not transferred but these compartments are close enough together that the energy can be). In the summer this process is reversed. In both seasons you get fresh air close to room temperature, combining health and comfort with energy savings. Your home can safely and efficiently ventilated this way. This system also filters out 95 percent of all pollens, mold spores, and dander in the incoming air while throwing all other fine particulates to the outside.
