Right - This evaporative cooler is wall mounted to reduce leak effects and allow for ease of maintenance.
Image
Right - This manufacturer's label shows a CFM higher than the requirement, increasing the likelihood that it will meet the performance level once installed.
Image
Right – A utility room provides adequate space for the home’s mechanical systems and electronic smart home monitoring equipment.
Image
Image
Image
Right: Maintenance valves are installed at the inlet and outlet of this central heat pump water heater
Image
Separate exhaust fans can share a common exhaust if each exhaust fan is equipped with a back-draft damper to prevent cross contamination
Image
Seperate dwellings with their own seperate exhaust terminations
Image
Image
Image
The back-draft damper on this exhaust fan is closed to prevent cross contamination
Image
The back-draft damper on this exhaust fan is open when the exhaust fan is operating
Image
The back-draft damper open when the fan is actively exhausting and closes when the fan is off
Image
The ENERGY STAR logo on the manufacturer’s label indicates this is an ENERGY STAR qualifying exhaust fan
Image
The manufacturer’s label found on this exhaust fan housing shows a sone rating of 1.0
Image
The natural draft and induced draft furnace are both Category I appliances that receive combustion air from the combustion appliance zone
Image
The raised hood at the base of the vent stack on this water heater shows that it is an atmospheric vented gas water heater

Image
This retrofit central heat pump water heater system utilizes the existing water heater as a swing tank to provide temperature maintenance for the hot water circulation loop
Image
This underground fuel tank is anchored to a concrete base to resist buoyancy forces
Image
Types of heat pump water heaters commonly used in central heat pump water heating systems include single pass units, multi pass units, and integrated units
Image
Wrong - the CFM rating may not meet the performance specification once installed, and the sone rating is too high.
Image
Wrong - Two exhaust terminations are joined in a roughly cut, restrictive hole that is not air sealed.
Image
Image
Image
Wrong: HPWH inlet and outlet are piped to mixing valve inlet and DCW make up, driving erratic HPWH and mixing valve behavior
Image
Wrong: The exhaust air from one heat pump water heater is blowing into the intake of the heat pump water heater next to it
