Home humidity and hardwood floors
My home in Southern Ontario has a lot of moisture in it.
The hardwood floor manufacturer claims that I should keep the humidity between 45% and 55%, so I’ve currently set my ERV to run at full speed if the humidity rises above 45%. However, my ensuite bathroom, the humidity is much higher. It’s regularly sitting at 60%, and after a shower can often hit 70%+. This has resulted in permanently damp windows in the bathroom with a lot of mold growing on them.
My current answer has been to get an energy star dehumidifier and place it in the bathroom to try and pull down the humidity in that room to 40%. At 40% there is no condensation, but there’s obviously an energy penalty to doing this.
Can I safely lower the overall humidity in the home without damaging my hardwood floors using the ERV? Is using the ERV a more energy efficient way of dealing with the issue?
