What is Heat Pump Water Heater?
A new heat pump water heater (HPWH) is an energy-efficient water heating system that uses electricity to move heat from one place to another, rather than generating it directly. This is because heat pumps function very differently than conventional water heaters. Rather than creating heat through burning or electricity, they move heat from the ambient air to the water, ensuring a reliable hot water supply.
This breakthrough technique cuts energy use by up to 80 percent while maintaining a consistent supply of hot water. Heat pump technology operates using a simple heat transfer process. The system utilizes a refrigerant to absorb heat from the ambient air, compressing this warmth to a higher temperature and transferring it to the water stored in the tank.
Heat pump technology works using the same process as a simple heat transfer. The system uses a refrigerant to absorb heat from the ambient air. It then compresses this warmth to a higher average temperature and transfers the heat to the water stored in the tank.
This process is essentially the reverse of how your refrigerator operates. The system quickly and efficiently extracts heat from the ambient air, even in colder areas such as a basement or utility room. In fact, it actually works better in the cold!
Its greatest strength is its efficiency. Heat pump water heaters can be more energy efficient than conventional electric or gas water heaters by up to three times. A conventional electric resistance heater is around 4,500 watts.
In summary, the heat pump water heating system stands out as a smart choice for those looking to enhance hot water availability while minimizing energy costs.
How It Differs From Traditional Heaters
The conventional units for water heating are either electric resistance water heaters or gas water heaters, while new heat pump water heaters simply move heat, using significantly less energy.
