Sizing an HRV/ERV System
Hello, I am choosing an hrv/erv for my 950 square foot house that is in the design stage, zone 6, coastal Maine. Using the formula, I have determined that the cfm rating for my house is 17, or perhaps 25 when my gf is around. I researched one unit and have attached the screen shot below. I can’t make sense of the table enough to know if this unit is properly sized for my house. I would appreciate help on this.
Also, since my ventilation needs seem to be small compared to most, can someone recommend a good mini unit? Naturally, I would like high SRE, Efficacy and ASE but would also like it to be affordable and quiet. I am leaning towards an erv in order to help with dry air in the winter, but would also consider a hrv. Come June, I will shut it off completely and open the windows until October. I am going for super tight, r-40 in the walls, r-60 in the roof.
