So, What’s the Deal with HRVs and ERVs?

question-mark

One thing that you’ll always, always, always hear us HVAC technicians talking about is energy efficiency, so surely, it must be pretty important!

But, there’s one problem: our homes are often sealed up so tightly that fresh air barely has a chance of making it inside! And yes, while this is great for efficiency, it’s horrible for indoor air quality. So, what can we do?

Well, one way that we can combat this problem is with a heat or energy recovery ventilator — which you may have heard about before. We understand that these systems can be a bit confusing and that many homeowners don’t quite understand what they do. That is why, below, we’ve explained it all! All you’ve got to do is keep reading to find out more!

What are HRVs and ERVs?

HRVs and ERVs are essentially mechanical ventilators, but with a twist: the heat exchanger. This allows them to transfer heat between air streams, allowing for proper ventilation without sacrificing efficiency.

To put it simply, during the summer, the HRV or ERV will transfer heat from the fresh, but warm, incoming air to the stale, but cool, outgoing air. This precools the incoming air so that your AC doesn’t have to work quite as hard. The reverse applies in the winter, as the system prewarms the incoming air, taking work off of your heater’s plate.

What’s the Difference Between an HRV and ERV?

HRV and ERV systems work similarly to each other in terms of temperature regulation. However, the major difference between these two systems is that an ERV, unlike an HRV, can transfer humidity in addition to heat.

What are the Benefits?

There are plenty of reasons to consider having an HRV or ERV installed in your home:

  • Better Efficiency: Perhaps the number one benefit of having one of these systems installed is better efficiency. And, when your heater and AC are energy efficient, it means you’ll spend less money on your energy bills.
  • Better Indoor Air Quality: With an HRV or ERV system in place, you won’t have to worry about opening a door or window to allow fresh air into your home. You can certainly expect your indoor air quality to improve.
  • Improved Comfort: Better indoor air quality combined with better efficiency means that you can expect your overall comfort to improve.
