Erv Vs Ventilating Dehumidifier In Ga Pv Heating Air However, a ventilating dehumidifier is often silly building science. to understand why, consider this: you'd only install a dehumidifier if it's humid out and you want it to be dry inside. Venting dehumidifier is for warmer climates (zone 3 or 4). in cold climate you want an erv, the energy penalty of no heat recovery in cold months is way too high. as for the rest, for a new build you want a ducted unit, ductless can be made to work but has too many issues.
Ventilating Dehumidifier Vs Erv R Buildingscience Ervs exchange sensible and latent heat between the intake and exhaust air, and hrvs only exchange sensible heat between the two sources. in other words, ervs buffer both temperature and humidity, whereas hrvs only buffer temperature. Erv's are a better strategy in climates with long, cold and dry winters because the house won't dry out like it will with a vdehu. To make a long story short, the erv will not keep the home dry, with high cooling loads or supplemental dehumidification. after several air changes of wet cool air, the fresh air entering through the erv has very little moisture removed. Does an erv remove or control humidity? learn about how energy recovery ventilators work and how they're different from dehumidifiers online today.

This guide explains hrv vs erv for humid homes, shows how each system works, offers climate specific picks, covers retrofit options, rates, controls, upkeep, costs, rebates, and the real indoor air quality gains you can expect. As shown here, erv's are better with houses that are tighter than 1 ach50. erv's are not dehumidifiers though. you'll still need a dehumidifier in addition to an erv in most climates. These systems are known as hrvs (heat recovery ventilators) and ervs (energy or enthalpy recovery ventilators). hrvs only exchange heat between the airstreams, while ervs exchange both heat and moisture. The erv brings in less but doesn’t dehumidify. if you want to ventilate and dehumidify at the same time, you need some type of supplemental dehumidification, such as a ventilating dehumidifier.
