what's the meaning of HRV?:blowzy:

heat recovery ventilation? lots of discuss in this forum for that topic.

it's an air exchanger for tightly sealed house (e.g. energy star or r2000), to bring in fresh air into your house and exhaust out staled air from your house for the seasons that you don't want to open the window (winter) during summer/warm weather, just open the window.
