After a few months of flawless operation our UltimateAir RecoupAerator ventilation unit started to make a horrible squealing sound after we turned on the boost for a morning shower. I turn it off and grunted. No one likes a new piece of equipment to malfunction this early in their lifecycle.
April saw the return of weather normalcy. (12% less heating degree days than March but only 8% less than the 10 year average, 7% more sun). This partially resulted in 25% lower energy usage in April. We used 49 kWh just for space heating. We also installed a clothes line outside and used the clothes dryer less this month. Our daily average usage was down 22% from March. We generated a 538 kWh surplus in April, our second surplus month in a row.
