what is the difference between hrv and erv systems？
What is the difference between an HRV and an ERV? HRVs and ERVs are similar devices in that both supply air to the home and exhaust stale air while recovering energy from the exhaust air in the process. The primary difference between the two is that an HRV transfers heat while an ERV transfers both heat and moisture.
Regarding this,Which is better ERV or HRV?
ERV or HRV - Which to choose? The best option between an HRV and an ERV depends on your climate and specific needs. If your house is too humid in winter (above 60% RH) then an HRV is the better choice, as it would surely get rid of excess humidity while an ERV would tend to keep it at a high level.
Furthermore,Is an HRV the same as an ERV?
The one major difference between HRV and ERV systems is likely to be the decision-maker when you're making your choice: HRV systems recover only heated or cooled air, depending on the season, but ERV systems recover both heat and relative humidity.
Furthermore,Will an ERV remove humidity?
Did you know that nearly 90% of the energy used to cool a home is required to remove humidity? While similar to HRVs, ERVs also remove humidity from the air before it is brought into the home – greatly reducing cooling costs.
Thereof,Are ERV systems worth it?
In sum, an ERV offers more consistent ventilation and better control over how much fresh air you're getting. It's also easier on your utility bills.

In winter, set the dehumidistat just low enough to prevent condensation on windows. Do not shut off or unplug your HRV. This can result in high humidity levels, which can lead to mould and mildew growth and unhealthy living conditions.
The most popular design of ERVs utilizes a des- iccant wheel to remove both heat and a significant amount of moisture from the incoming air, which reduces the load on the air-conditioning system.
Their ability to exchange heat between the supply and exhaust air streams reduces the cost of heating or cooling the healthy fresh air circulating through the home. HRVs are sometimes called air-to-air heat exchangers because they preheat or cool incoming air using exhaust air.
The answer depends on your home's air conditioning system, your ERV wall control, the outdoor temperature and, most importantly, the outdoor relative humidity. As a rule of thumb, if you are more comfortable outside than inside your house, you should run your air exchanger in the summer.
Don't run the ERV in the winter as it will dry out the home. Not True. In winter the ERV will recover up to 60% of humidity from the outgoing air and add it to the incoming air. As a result, continuous operation is usually appropriate.
Installing an ERV air exchanger is a great way to ventilate your home and intake fresh air but they are not capable of providing adequate moisture control. To ventilate and dehumidify at the same time you will need supplemental dehumidification.
Do You Need a Dehumidifier If You Have An HRV? The answer is Yes, generally speaking. Just like we already stated, an HRV may not remove as much humidity as a dehumidifier. This is because a lot of heat and moisture exchanges take place depending on the season.
