What is an ERV unit?

But just what is an energy recovery ventilator? ERVs are systems designed to be connected to the ducts that are part of your HVAC system. By way of two fans, ERVs draw clean, fresh air into a home or office and remove stale air.

What is ERV control?

ERV systems offer a balanced approach to fresh air ventilation. The unique dual-stream airflow design of Field Controls’ Energy Recovery Ventilation system keeps outgoing stale air separate from incoming fresh air and completely rejuvenates the air throughout your entire home up to eight times a day.

How does a ERV system work?

An ERV Captures Energy From Exhaust An ERV works by capturing the air that’s exhausted from your home and using that air to create the energy needed to ventilate your house. The ERV also treats the air the device ventilates into your house, instead of letting in humid Georgia air like a fan would.

What is electrical ERV?

Energy recovery ventilation (ERV) is the energy recovery process in residential and commercial HVAC systems that exchanges the energy contained in normally exhausted air of a building or conditioned space, using it to treat (precondition) the incoming outdoor ventilation air.

Is an ERV necessary?

Why Do You Need An ERV? An energy recovery ventilator can be a helpful tool if you’re struggling with your indoor air quality. If your home air smells or tastes stale and there’s nothing that fans or air conditioning can do to help with it, an ERV can be a good piece of equipment to change that.

Are ERV 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.

How does ERV control humidity?

ERVS transfer heat and water vapor through incoming and outgoing airstreams. Water vapor will move from the more humid air stream to the less humid air stream, trapping moisture generated inside.

Should ERV run continuously?

To maintain air quality set the ERV controls to the intermittent on off cycle. This continuous intermittent setting should be maintained all year round. If you have a party or are cooking food with odours you can turn the control to high for an hour or so.

Are ERV required?

In new buildings, every dwelling unit shall be served by a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) installed per manufacturer’s instructions.

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.

Does an ERV replace an air conditioner?

Energy Recovery Ventilators Pre-Cool Fresh Air How does an ERV do this? It isn’t because there’s an extra air conditioning system cooling down the incoming fresh air. Or ice, or cold water, or anything like that.

Should I run my ERV continuously?

Should I run my ERV in the summer?

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.

Does ERV remove moisture?

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.

Will an ERV remove humidity in winter?

The ERV heats (or cools) cold (or hot) air coming from outside with air being exhausted from inside to save energy. It also removes humidity from incoming air in summer and adds humidity to incoming air in winter.

Should I turn off ERV in summer?

Don’t run the ERV in summer as it will create humidity. The ERV contains an Energy Recovery Core (made of polymerized paper and aluminum) that decreases the humidity of incoming air in the summer by up to 60%. (This Recovery Core acts like a membrane moving humidity for the incoming air to the outgoing air.)

How long does an ERV last?

ERVs have a warranty of around two years and will last over 20 years if properly maintained. An HRV system, on the other hand, typically has a lifespan of 10–15 years. You can increase the lifespan of either type by taking good care of its fans, vents, ventilation core, filters, and other components.

How much does an ERV cost?

All in all, the national average of an energy recovery ventilator with installation is approximately $2,000, and the typical price range lies between $1,500 to $2,000.

What is the cost of an ERV system?

All in all, the national average of an energy recovery ventilator with installation is approximately $2,000, and the typical price range lies between $1,500 to $2,000. What is this? Keep in mind that costs can add up quickly, particularly if you are an amateur and have never installed an ERV before.
