Single-stage and two-stage heat pumps differ in their operation and offer distinct benefits::
Single-stage heat pumps have one output setting. They either run at full power or are off, which can lead to temperature fluctuations and higher energy bills.
Two-stage heat pumps can operate at both high and low speeds. The lower setting provides gentle heating or cooling for most days, while the higher setting kicks in during extreme temperatures, ensuring optimal comfort in all conditions. Two-stage heat pumps tend to be more energy-efficient and offer more consistent temperature control improving home comfort.
