Question about the Panasonic spot ERV
I work for a non-profit organization weatherizing homes. I live in the deep South, so ERVs provide good potential benefits in this region.
We’ve recently installed two of these units but were disappointed in the cfm reading we got. the unit is advertised at 40 cfm, however using the flow pan and manometer the highest reading I could get on this unit was around 11 CFM.
I was hoping to get some insight on this unit concerning this issue. I could be testing wrong (i test at the site of the unit, but some contractors say I should test this unit at the outside exhaust), maybe we’re installing them improperly, or maybe the low reading is what we should expect.
I’d be very thankful for any information on this unit especially someone who is used to dealing with them.
