A heat pump with whole house dehumidifier is an integrated HVAC solution that combines the efficiency of a heat pump with the moisture control capabilities of a whole-house dehumidifier. This system provides year-round comfort by regulating both temperature and humidity levels throughout the home. It offers improved energy efficiency, better indoor air quality, and enhanced comfort compared to traditional HVAC systems.
What is a Heat Pump with Whole House Dehumidifier?
A heat pump with whole house dehumidifier is an advanced HVAC system that combines two essential functions:
- Heat Pump: Transfers heat from one area to another, providing both heating and cooling.
- Whole House Dehumidifier: Removes excess moisture from the air throughout the entire home.
This integrated system offers several advantages:
- Improved energy efficiency
- Better indoor air quality
- Enhanced comfort
- Year-round temperature and humidity control
How Does a Heat Pump with Whole House Dehumidifier Work?
The system operates in two main modes:
- Heat Pump Mode:
- In summer: Removes heat from indoor air and transfers it outside
-
In winter: Extracts heat from outdoor air and brings it inside
-
Dehumidification Mode:
- Draws moist air from the home
- Cools the air to condense moisture
- Removes water through a drain line
- Reheats the now-dry air to the desired temperature
- Circulates the dehumidified air back into the home
