Erv Instead Of Bathroom Fan

I have a panasonic bath fan with a 30 min timer and a fantech erv set to 0 35 ach.

Erv instead of bathroom fan.

Often will add bath fans if the hrv size doesn t allow a boost rate of at least 50 cfm per bathroom. Alternatives to ducted bathroom fans wall fans. We ve managed to set up the erv to run the exhaust fan continuously but this then causes other problems. Wall fans blow air from the bathroom into the room on the other side of the wall then sucks the clean dry.

Panasonic makes a specific bathroom erv panasonic whispercomfort spot erv fv 04ve1 the other alternative is to use both a bathroom fan for spot exhaust on a timer and a separate hrv or erv. You can do this with a bath fan installed to blow air into the home or you can use a fan made specially for this task. My suggestion is stick with a dedicated exhaust fan. This system can also be set up to draw from bathrooms instead of hallways thus eliminating bathroom exhaust fans.

Don t need a 200 cfm hrv in most cases even for large houses in terms of normal ventilation rates 62 2 2010 not 62 2 2013. A window is a simple option. This is what i am running. But when the erv hrv is not running the homeowner should be able to have a switch in the bathroom s to run the unit when it is not otherwise in run mode or some type of override switch to.

Put the bath fan in the 1 2 bath first then the bath likely to get used the least. I m thinking of the qufresh fan made by air king. Differing air flows through the hrv erv can occur due to pressures created by the central air handler in the trunks.
