Geothermal (ground-source or water-source) heat pumps achieve greater efficiencies by transferring heat between your home and the ground or a nearby water supply. Even though they cost more to set up, geothermal heat pumps have reduced operating costs because they take advantage of relatively steady ground or water temperatures. Geothermal (or ground source) heat pumps have some significant benefits. They can decrease energy usage by 30%-60%, control humidity, are sturdy and dependable, and fit in a vast array of homes. Whether or not a geothermal heat pump is suitable for you will depend on the size of your lot, the subsoil, and the landscape. Ground-source or water-source heat pumps may be utilized in more extreme climates than air-source heat pumps, and client satisfaction with the systems is extremely high.

A new type of heat pump for residential systems is that the absorption heat pump, also referred to as a gas-fired heat pump.

Several innovations are improving the performance of heat pumps.

Unlike standard compressors which can only operate at full capacity, two-speed compressors allow heat pumps to operate near the heating or cooling capacity needed at any specific moment. This saves considerable amounts of electric energy and reduces compressor wear. Two-speed heat pumps also work nicely with zone control systems. Zone management systems, often found in larger houses, utilize automatic dampers to allow the heat pump to maintain unique rooms at different temperatures.

Some versions of heat pumps are equipped with variable-speed or dual-speed motors in their indoor fans (blowers), outdoor lovers, or both. The variable-speed controls for all these fans try to keep the air moving in a comfortable pace, minimizing cool drafts and optimizing electric savings. Additionally, it reduces the noise from the mill running at full speed.

A desuperheater-equipped heat pump can heat water two to three times better than a normal electric water heater.
