How do I size an HRV system?
ERVs/HRVs are typically sized to ventilate the whole house at a minimum of . 35 air changes per hour. To calculate minimum CFM requirements, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .
What is vanee HRV?
HRV – Heat Recovery Ventilator Ideal for colder climates. In colder climates, where home heating is essential, the heat recovery ventilator (HRV) is the proper choice. The HRV keeps the home supplied with a steady flow of fresh outdoor air.
How many CFM HRV do I need?
For continuous indoor air quality ventilation, a heat or energy recovery ventilator (HRV or ERV) should provide 0.35 air changes per hour. This calculation must consider the complete occupied volume of the house. This rate can be more easily calculated by allowing 5 CFM per 100 square feet of floor area.
How do I choose an HRV?
Making your choice. The choice between HRV and ERV units depends, in large part, on the humidity levels in the building—but the following points should also be considered: Number of people in the home – An HRV fits the needs of a larger, active family that generates a lot of humidity.
How do I calculate CFM for my house?
This practical math formula goes a long way when you’re considering air ventilation improvement in an indoor space:
- CFM = (fpm * area), where fpm is the feet per minute.
- To find the cubic feet per minute, substitute the FPM value with the area after the area is squared.
Should you run HRV in 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.
How much is a vanee HRV?
Price: $1,244.00 VIRTUO AIR TECHNOLOGY Introducing Virtuo Air TechnologyTM, the first air exchanger artificial intelligence that allows the airflow verification, the auto-balancing and self-adjusting to changing indoor and outdoor conditions.

Can you Oversize an HRV?
In other words, don’t oversize the HRV so it can be boosted to high speed to clear bathrooms quickly. Use a smaller HRV along with spot ventilation fans in bathrooms. As with all ducted systems, it’s crucial to run the ducts inside the building’s conditioned space.
How do you size a heat recovery unit?
HRVs and ERVs are generally sized to ventilate the entire house at a minimum of 0.35 air changes per hour. To determine the lowest CFM requirements, take the square footage of your home and multiply it by the ceiling’s height. This figure is the cubic volume. Next, divide the result by 60 and then multiply by 0.35.
Do HRV systems reduce humidity?
HRV / ERV’s are a very cost effective way of reducing indoor humidity levels when the outside air is colder than the inside air of the home, the colder the air the greater the capacity for an HRV/ERV to dehumidify.
