Should ERV run all the time?

An ERV doesn’t need to. While the ERV contains a fan that’s less powerful than your HVAC fan, it’s still powerful enough to ventilate your entire home. The ERV fan can run all the time, providing more consistent ventilation. Efficiency: Compared to an HVAC blower fan, your ERV’s fan is less expensive to operate.

Where do you mount ERV?

Installing an Energy Recovery Ventilator

The fresh air intake should be located where fresh air circulates, and away from driveways, range hood exhausts, furnace flue and laundry vents.
The stale air from the home should come from a wall close to the kitchen, within one foot of the ceiling and 10 feet away from an oven.

Can an ERV be installed outside?

“O” Series energy recovery ventilators are designed for outside use in rooftop or “pad” installations where the application requires a “over and under” duct system. One of the benefits of this design is the ability to be ducted directly to the back of a rooftop air conditioning unit.

Do I need a humidifier with an ERV?

An energy recovery ventilator (ERV) actually recovers some of the humidity from the exiting air and keeps it in the house. For that house a heat recovery ventilator (HRV) is a better choice: it recovers sensible energy, but allows all the moisture to leave the house.

Does an ERV dehumidify?

Although, it should be made clear that ERV systems are not a reliable source to remove moisture; an ERV system is not a dehumidifier and actually guarantees that a dehumidification system will be necessary.

Does ERV control humidity?

ERV ventilation solutions offer balance, humidity control and comfort. 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.

Can ERV provide cooling?

The difference this makes can be tremendous: an ERV can recover more than 80% of the energy of the air conditioning system and use it to cool down the incoming fresh air. And, as mentioned above, an ERV also works in winter—it just allows the warm indoor air to heat up the cool outdoor air.
