A HRV is a Heat Recovery Ventilator, its basically a heat exchanger that uses your exhaust air to heat the inlet air. HRVs can be run 24/7 or set to run on a timer. Usually houses that have HRVs dont have seperate bathroom exhaust fans (at least not in every bathroom) from what I noticed when I looked at show homes and friend's houses with HRVs.
In my experience last winter, I had water drip out of my ceiling speakers in my master bathroom, I took out the speaker and noticed that the insulation was a bit light above the speaker, the builder had the blown in insulation topped up for me.
