ERV vs. HRV

Posted on Tue, Jan 08, 2019

Energy Recovery Ventilation or Heat Recovery Ventilation?

There is quite a bit of debate out there as to where ERVs should be used and where HRVs should be used. For those of you who do not know, HRVs, or heat recovery ventilators, like ERVs, are ventilation systems that transfer heat. However, unlike ERVs, heat recovery systems do not transfer moisture. This aspect significantly reduces HRVs capabilities in comparison to ERVs, making energy recovery units the more logical choice.

We see a lot of maps claiming that ERVs should be used in the humid South to reduce incoming moisture, while HRVs should be used in the colder North. However, these maps are inconsistent (for example, some suggest HRVs should be used in the arid Southwest). Moreover, they are wrong; ERVs can and should be used everywhere. As our graphic playfully shows above, we believe HRVs are suited for the Bermuda Triangle.
