Q:

How does one form a comparison of heat pumps?

A:

Quick Answer

Heat pumps can be compared according to their overall efficiency, compressor types, motor types and noise levels. An individual should determine whether his local climate is appropriate for a heat pump before purchasing one. Heat pumps usually work better in areas with a moderately cool climate.

Heat pumps should be designed to be as efficient as possible to help users save on operating and energy costs. Some pumps are designed to use wasted heat as a method of heating up water while the pump is cooling. The type of compressor a heat pump has can also determine how efficient it is.

Compressor types include two-speed compressors and standard compressors. Two-speed compressors allow heat pumps to work more efficiency by ensuring they operate at the required capacity while standard compressors consistently operate at the highest capacity no matter the setting. A two-speed compressor heat pump may not require as much maintenance as a standard compressor since the unit isn't under as much strain.

Motor types include dual speed and variable speed motors. Motors are designed to create a more consistent air velocity and to make the heat pump more energy efficient. A newer motor can also reduce the amount of noise a heat pump makes since the blower doesn't have to operate as frequently.
