Re: wave ventilation
After reading the supplier's web-site I'm left with thinking this just a large fancy exhaust fan .... similar to a bathroom or kitchen exhaust fan.
The part I find disturbing is they are stating this system brings in fresh air through gaps in windows and doors from the upper level in the home.
The part that is disturbing is this system is actually causing a negative pressure within the home which can be dangerous with combustion equipment .... boilers , furnaces , water heaters ... that are commonly found in the home's basement.
In my opinion you would be better off with a HRV/ERV or an air to air exchanger .... at least these maintain controlled ventilation with minimal negative pressures ( if at all ).
