Because the heat pump water heater exhaust air is cool, should I duct it to outside the home?
No. Although the exhaust air is typically cooler than the room air, it is usually much warmer than the outside air during winter months in Colorado. Ducting the exhaust air outside will pull in more outside air to take its place, and will therefore increase the energy use of the house.
Can I put a heat pump water heater in my finished basement? Won’t it take away from the efficiency of heating my house, by exhausting cool air into the basement?
Yes, it’s fine to put the heat pump water heater in a finished basement. You should just make sure the cool exhaust air from the water heater does not blow directly into commonly occupied areas. Yes, this will add a small amount of energy to the home’s overall heating load. However, this amount of cool air from the heat pump water heater will have a minimal effect on the home’s overall heating system performance/consumption. In addition, the cool air will help keep the basement cool in the summer months, reducing the energy used for air conditioning.
Where should I put the heat pump water water heater? How big does the space need to be?
Basements, utility rooms, and laundries are great locations for a heat pump water heater. Pick a spot that will not be frequented by occupants, and position it away from bedrooms and living spaces to fully mitigate any noise concerns. Heat pump water heaters mildly dehumidify the air around them, so they can be a helpful addition to a root cellar or pantry. You can locate the water heater in a small space as long as there is adequate airflow. This can often be achieved by installing a louvered door and grills or grates or similar air gaps.
