How Heat Pump Hot Water Systems Work
A heat pump hot water system works by extracting heat from the surrounding air and transferring it to heat your water. You’ll find a fan that draws in air, passing it over an evaporator coil filled with refrigerant. This refrigerant absorbs the heat, turning into a gas. Next, a compressor squeezes this gas, raising its temperature before it flows through a condenser coil. Here, the heat transfers to your water tank, warming your water efficiently. After releasing its heat, the refrigerant cools and turns back into a liquid, ready to cycle again. This process runs continuously, ensuring a steady supply of hot water without directly heating it with electricity or gas. You’ll appreciate how this method cleverly uses ambient heat to do the job.
