Heating FAQ: Is an Energy Recovery Ventilator Right for Me?

If you’re like most other homeowners then you’re looking for any way to reduce the amount of energy that you use to heat your home. Many homeowners have started looking into energy recovery ventilators (ERV) to try to reduce the energy demands of their heating systems in Salt Lake City. These types of systems require very little energy to run but can result in huge increases in efficiency. At Design Comfort, we offer complete energy recovery ventilator installation and repair in Salt Lake City. Our technicians have years of experience working with all different kinds of ERVs and can help you pick out a great system for your home. We thought it would be a good idea to put together a quick explanation of how they work and the potential benefits.

How Do Energy Recovery Ventilators Work?

ERVs are normally installed in the ductwork of your home. In heating mode, your furnace or heat pump pulls in cool air from the outside, heats it up and then pushes it into your home. After that hot air travels through your home and cools down, some of it gets pulled back be re-heated while the rest gets exhausted outside. The air that gets exhausted still has some heat energy in it. An ERV allows the cool, incoming air to acquire some of that heat energy by pushing it over a heat exchanger. The two air streams aren’t allowed to mix so that the new, fresh air isn’t contaminated by the stale, outgoing air. Some ERVs have humidity recovery systems that allow you to recover some of the moisture that would be lost in the outgoing air.

What Are The Benefits of Energy Recovery Ventilators?

So what’s the bottom line with ERVs—how much can you save? That question is difficult to answer because each system has its own efficiency ratings and capabilities. Some ERVs can achieve up to 85% heat transfer efficiency. That translates to a significant amount of energy savings for your home. But some systems can have as low as 50% transfer efficiency. But in most cases, the electricity required to run the ERV is much less than the energy savings that they can achieve.
