How about a commercial one-room HRV for an off-grid home?

Scott Wilson | Posted in Energy Efficiency and Durability on

In one of my threads Martin suggested using a small bath fan rated at about 4 watts to ventilate my off grid cabin. BC building  codes require a ventilation unit that runs 24/7 and I’m hesitant to rely on a fan that is basically enclosed inside the bathroom in order to ventilate the whole cabin.

Then someone mentioned a small commercial HRV in another thread.

On the lowest setting it uses 4.2 watts (listed under “specifications) and can ventilate up to 650 sq’ (the size of my cabin. This unit should work, shouldn’t it?

    Looks good. The medium speed setting of 26 CFM is pretty close to the 23 you decided you needed, with room to adjust up or down from there.
