Tightening a home’s envelope may reduce the air supply needed for combustion, and when there’s not enough combustion air, equipment could have combustion ventilation problems. Thus, the people who sealed up homes (often referred to as the weatherization industry) needed a way to determine if sealing a home up would undermine the safe operation of combustion equipment. To meet this safety need, they embraced combustion appliance zone (CAZ) depressurization testing.
The geothermal industry is acutely aware that government-issued commercial and residential tax credits are set to expire at the end of 2016. Currently, geothermal heat pumps in commercial applications are eligible for a 10 percent income tax credit, and residential applications may receive up to a 30 percent incentive.
