What is it?

Residential energy recovery ventilations are designed to provide a comfortable living environment by transferring heat and humidity from outgoing air to incoming air during colder months, reducing demand on heating and humidification equipment. Similarly, they remove humidity from incoming air during warmer months, reducing demand on air-conditioning or dehumidification equipment. Our ERVs feature high-quality motors from reputable brands, ensuring maximum energy efficiency and quiet operation. The filters have a large dust-holding capacity and a long service life, ensuring reliable and safe operation. Each model is built with high-quality steel, making them durable and reliable even in extreme conditions.

What are the main components?

The main components of HRV/ERV devices: heat exchanger, filters, intake and exhaust fans and motors, controllers.

How Does It Work?

Energy recovery ventilation systems are designed to capture heat from outgoing air during the heating season and use it to preheat incoming fresh air. Conversely, during the cooling season, the system can reverse the heat-exchange process, removing some of the heat from incoming air and transferring it to the outgoing air. ERVs also transfer heat and water vapor through incoming and outgoing airstreams, effectively returning moisture to where it originated.

How Many Types?

l  There are four installation forms including ceiling, floor, cabinet, wall-mounted, and other types.

l  Additionally, there are two types based on air flow organization, which are one-way flow and two-way flow.

l  There are two types based on indoor air pressure, positive pressure and negative pressure.

l  Lastly, there exist two types of energy recuperation mechanisms: heat recuperation ventilators (HRV) and energy recuperation (or enthalpy recuperation) ventilators (ERV).

HRV vs ERV: Which is better for Net zero building

A net zero building is achieved by using efficient technology, such as heat pumps, high-quality windows, and insulation. An Energy Recovery Ventilation (ERV) system is ideal in this situation, as it transfers heat and moisture from indoor exhaust air to fresh outdoor air, saving energy.

How Much Does It Cost?

The energy recovery ventilator is an all-inclusive ventilation system that is highly efficient, eco-friendly, and saves energy. It is commonly found in various places such as hospitals, hotels, airports, offices, villas, and entertainment venues. The technical aspects of this system are advanced, providing excellent ventilation and heat recovery, which results in a higher price than regular ventilation equipment.

What Is It Used For?

Energy recovery ventilators provide equal amounts of air supply and exhaust. It regulates the moisture levels in your home, especially during the summer when they can reduce humidity and prevent mold growth, thus improving air quality.

If you lack an exhaust fan in your bathroom or kitchen, it's necessary to install one. However, if you already have one, there's no need for another. Nevertheless, it's not recommended to use an HRV/ERV to eliminate cooking fumes as it may harm the heat exchanger core.


By using ERVs, you can lessen the frequency of running your heater and air conditioner, which in turn, decreases the damage they undergo. Moreover, they obstruct pollutants from obstructing air filters or causing problems like unclean or damaged ductwork. ERVs can also minimize bothersome and expensive malfunctions and extend the lifespan of your HVAC system.

How do you know if you need an ERV?

If you're facing issues with the quality of air inside your house, an energy recovery ventilator can prove to be quite useful. In case you've noticed a stale or unpleasant odor, and your fans or air conditioning systems aren't doing much to improve the situation, an ERV can come in handy. It's a valuable device that can help you resolve such problems.

How big of an ERV do I need?

To ensure proper ventilation throughout the entire house, HRVs/ERVs are usually designed to provide at least .35 air changes per hour. To determine the minimum CFM needed, just multiply the square footage of the house (including the basement) by the height of the ceiling to obtain the cubic volume.

Can you oversize an ERV?

Oversizing an ERV is actually beneficial, unlike a heating and cooling system. It's generally recommended to have more ventilation, as long as it's properly balanced and recovers some heat and moisture.

Do you need bathroom fans if you have an ERV?

To ensure proper ventilation, it is necessary to have local exhaust fans in both kitchens and bathrooms, unless the ventilation is already being taken care of. Nonetheless, it is not advisable to use an HRV/ERV to draw out fumes from a cooking area, as this may lead to the heat exchanger core becoming contaminated.
