Best solution for high humidity retrofit

cdbh12 | Posted in Green Products and Materials on

Anyone heard of Lunos E2 units being used in a retrofit with high humidity in Ontario? Or has anyone used a Lunos Nexxt system? My Rep assessment said I needed to bring in about 53 com fresh air, so I would need 2 of the E2 series making 4 holes in the wall without addressing basement humidity. I live in a 980 sf bungalow end unit and humidity is often 55 , winter or spring. Two days ago it was 61. Mould starts to grow on the glass door edging. The furnace is about 15vyears old and does not bring in fresh air. I’m not sure an Hrv makes sense since the place is so small. I understand Zehnder might be a good alternative. Any direction would be good.

    Cdbh12,
    It's hard for us to address your situation from the information you have provided.

    The first step in any investigation of an indoor humidity problem is to identify the source of the moisture.
    We haven't done that yet.

    Do you have a damp basement? Are you fairly confident that the basement is the source of the moisture?

    Not sure at all about the basement being the source. Having to run the dehumidifier so often would support it in my view. There is also a certain amount of moisture from laundry - hanging items in the small laundry room which has an exhaust fan. I could replace the bathroom, laundry, and stove exhaust fans since they are older base models, but the recommendation to add 53 crm of air exchange is also playing a factor.

    Cdbh12,
    A solution requires a full assessment of your home, and we can't do that. Ventilating a house in winter tends to lower the indoor relative humidity, but ventilating a house during the summer is much more iffy -- in some weather conditions, ventilating during the summer can raise rather than lower the indoor relative humidity.
