Green Building Q&A: Bathroom vent fan with ERV/HRV in older house that isn't the tightest.
Performing a remodel/energy bolster on an older 700 sf house. I don't want to go through the trouble of a whole house balance vent system. I am considering a bathroom fan w/ heat recovery, such as the Panasonic unit. My questions/concerns: 1_Climate zone 7 9000HDD. Will the core freeze? ERV's I have installed on other projects cycle into recirc x minutes per hour to prevent this. 2_Will the panasonic unit effectively reduce moisture in the one bathroom given that it is an ERV? 3_Is there another brand besides panasonic, perhaps one that is an HRV with a drain line to get rid of the moisture?
