The results from the "CogFx" study are compelling, showing that people in environments with low VOCs and low ambient CO2 levels score higher on tests of cognitive function.  Specifically, they show that providing 40cfm of outdoor air per (actual live) occupant results in significantly higher scores than even the "Enhanced Ventilation" scheme...

Has anyone used a commercial heat pump water heater for a large protect?  I have found a few manufacturers for this technology, but want to make sure this is a viable and cost approach to electrical eliminate gas on a path to all electric.

Thanks in advance.
