What Is a Heat Pump Hot Water System?
A heat pump hot water system works similarly to a home heat pump. Instead of generating heat directly like a traditional electric cylinder, it extracts warmth from the surrounding air and uses it to heat your water. Because of this, heat pump systems can use significantly less electricity than standard electric hot water cylinders.
