Any advice on adding a ventilation to an in basement all electric 10 gallon HERMS System? My fist attempt without any exhaust system tuned my basement into a rain forest! Next tried an 80CFM bathroom vent right above the boil kettle. Got better results, but also go some condensate dripping into my kettle. I?m thinking now of adding a kitchen style hood. How many CFM does one really need, and does the height above the kettle make a difference? Any direction in this endeavor will be much appreciated!
