How the Vaughn Heat Pump Water Heater Works
The Vaughn Heat Pump Water Heater uses a small amount of electricity to transfer heat to the water from the surrounding air. In comparison, traditional electric water heaters use resistive heating elements to directly heat the water. The Vaughn Heat Pump Water Heater is significantly more energy efficient when compared to a conventional electric water heater because the heat pump utilizes considerably less electricity than a standard electric unit. In essence, a heat pump works like a refrigerator in reverse. A refrigerator moves heat from inside the refrigerator (making things cold) and transfers that heat energy to the surrounding room, whereas a heat pump water heater captures free and essentially unlimited heat from the ambient air and transfers that heat to the water stored in the tank. The Vaughn Heat Pump Water Heater can capture heat from air as cool as 40°F. If the unit cannot provide enough heating capacity to meet the demand, the back-up resistive heating elements will activate to ensure the unit provides sufficient hot water. The process of removing heat from the air and transferring it to the water results in the exhaust of cooler dryer air. This added benefit of dehumidifying the surrounding air can provide as much as 0.4 gallons per hour of "free" dehumidification provided by the heat pump unit is heating water.
Heat Pump Functions
- The built in fan draws room air into the water heater heat pump compartment and across an evaporator coil, and exhausts cooler and slightly dryer (dehumidified) air.
- The evaporator coil captures heat energy in the air and transfers that energy to a specially formulated CFC free refrigerant contained within the evaporator.
- The refrigerant changes from a liquid to a gas as it gets warmer.
- The refrigerant, now as a warm gas, exits the evaporator and passes into a compressor.
- The warm gas is compressed, causing it to become a superheated hot gas and then flows to the heat exchanger.
- The heat exchanger transfers heat energy from the superheated hot gas to the cold water from the tank.
- The pump circulates cold water from the tank through the heat exchanger resulting in a continuous transfer of heat energy from the superheated gas to the water.
- Hot water exits the heat exchanger and is stored in the tank.
- The superheated gas condenses back to a liquid and awaits to repeat the process.
Selectable Operating Modes
|Storage Capacity (Gallons)||Part Number||Dimensions (Inches)||Shipping Weight (lbs.)|
|Overall Diameter||Overall Height||Floor to T&P and HW Outlet||Floor to CW Inlet|
- Installed location must be at least a 10' x 10' x 7' room (700 cubic feet of air space). If smaller, there must be louver installed to provide sufficient airflow.
- Installed room location must not be cooler than 40°F.
- Installed locations with warmer ambient air temperature (i.e. furnace room) provides abundant "free" heat and is advantageous.
- The heat pump dehumidifies the air and as a result produces condensate which must be piped to drain or outdoors.
- The washable air filter requires periodic cleaning. Frequency depends upon environmental conditions.
