You should check with your local code or the forced air system s manufacturer.
Air exchanger installation guide.
If you can install the stale air intake on one level and the fresh air output on another level then a ductless hrv installation works perfectly.
Supply air from hrv or erv must be at least 3 feet from the forced air system.
Picking the best system would be best done with the help of an hvac specialist i think.
Caution the hrv and forced air system must be in continuous mode to achieve maximum comfort and to avoid cross contamination.
An air to air heat exchanger brings two air streams of different temperatures into thermal contact transferring heat from the exhausting inside air to.
Or just a standard fan or two that blow in opposite directions.
The trick is locating the stale air intake and fresh air output ducts in such a way that they cause air to circulate throughout the house.
In both instances you have to remove the core from the system.
Air exchanger are installed in most new homes today they work with the existing hvac system to ensure fresh air is coming into the home.
In this section you will find installation manuals technical data sheets and product brochures for venmar products.
Check the manufacturer s instructions and oil as often as recommended.
Using a lunos ductless air exchanger or productair ductless ervs to circulate air between 2 floors in a home would be a lot of money spent for nothing i think.
Some air exchanger motors require additional oil over their lifespan.
If you have an hrv or an erv you have to clean the core.
If you have that much moisture i would think about a dehumidifier maybe and with any double pane window you are bound to get humidity on the really days anyway.
One way to minimize air quality and moisture problems in a home without opening a window is by the installation of a mechanical ventilation system such as an air to air heat exchanger.
Clean air exchanger core.
Have you considered a ceiling fan.
Air exchangers kitchen hoods.
Air exchangers are a great idea but with existing homes its best to go on a case by case basis.
