    Hey
    I have a question? I have a 200 square
    foot tiny house with closed foam insulation and because I also use it as a greenhouse
    in the winter time and of course because of transpiration of the plants and
    evaporation of the soil after a watering… on top of two adult people breathing,
    I am getting a lot of humidity in the winter time. I also live in the SW Virginia area so we
    have pretty humid summers here too. Which
    system would work best for this application and HRV or ERV? I know both clean the air Im just more
    concerned with excessive humidity. I see
    a lot of people in tiny houses using HRV but what do you think I should
    do. Also I am looking for a very small
    unit… any ideas there because its again only 200 sq ft?

    What should we use in the Washington DC metro area HRV or ERV for ventilation? the summers are hot and humid and the winters are cold and dry and we don’t want our houses to become very dry in the winter or very humid in the summer.? And I just want to know that fresh air is important for the health of the people in our homes in North America especially important that all new built and existing homes that are going under a renovation in North America are Much tighter then ever before to keep the heat in the winter and the air-conditioning in the summer and save energy

      I live near DC (NOVA) and first I would highly recommend adding whole house humidification. Depending on the size / age of your home and the location of our furnace you can accomplish this with a bypass style humidifier - good in most homes, cheapest to install, etc. A better type (more expensive) is a steam generating humidifier. Once you have that installed I would then add an ERV. Why? in the winter you are adding moisture (humidity) into your home if you have a humidifier and an ERV allows you to impart some of that moisture into your fresh (dry) ventilation air. In the summer you are removing humidification from inside your home and again the ERV removes some of that humidity from the fresh air coming in. The HRV only allows the temperature of the air to "exchange" so in the winter when you add ventilation air it raises the temp but still comes in "dry". I don't know off hand how effective an ERV is at removing humidity in the summer. In theory even an HRV can remove some humidity from hot moist incoming air by simply lowering the air temp. (if the incoming outside air temp. is reduced to the dew point or lower) what I don't know is would an ERV allow an even lower drop in humidity... either way I would go with the ERV but I would also add a whole house humidifier.

    so what about a new home in a cold area that uses wood heat as the primary heat and no ac in the summer and lack of humidity is a concern?

    So I have to wait a day and a half to be able to run my system to let that or dry... why not just have an exchange program will you charge your core we can swap them out instead of having to wait

      melv929 That’s what I was thinking too.

      Paul Wehr what’s that mean? Can you explain

    • @markterzigni2526

      Or simply purchase a second core and set of filters so it is a simple swap out. Clean the old stuff so it is ready for the next swap out - or use a service as suggested.

    An Hrv are not good for homes. They actully dry up the house too much, you’ll need a humidifier to put water back in the air. Your better off getting a erv machine because it
    also controls the humidity.
