Heat Pumps Comparison: basic principles What is a Heat Pump? A heat pump is a device that is able to transfer heat from one fluid at a lower temperature to another at a higher temperature.
If electric is your only option, an ENERGY STAR certified heat pump water heater uses half the energy of a standard model and can save a family of four up to $3,500 over its lifetime by heating water using highly efficient heat pump technology.

We expect our air to water heat pump to have an average coefficient of performance (COP) of 3.7 at an outdoor temperature of 45°F (7°C) and a COP of 1.3 at an outdoor temperature of -5°F (-20°C). The air to water heat pump will is available in sizes up to 6 nominal tons, so one unit can heat and cool an entire home.

ANSI/AHRI 1160 (I-P/2014): Performance Rating of Heat Pump Pool Heaters (with Addendum 1) Program Scope A heat pump pool heater consists of one factory-made assembly, which contains the air moving device, compressor, refrigerant-to-water heat exchanger and air-to-refrigerant heat exchanger using ambient air as the heat source.
The centrifugal heat pump system was separately tested first to get the actual energy performance of PSF centrifugal heat pump unit. For 500RT PSF centrifugal heat pump unit, the field tested average heating capacity and power consumption of 1# centrifugal heat pump unit is 1714.9 kW and 247 kW, respectively, which is shown in Fig. 6.
Another example of an air-to-water heat pump system would be a pool heater. In this case, heat from the outside air is used to heat the water in a swimming pool. Q: Can you give me some examples of a water source heat pump? A: Water source heat pumps use water as the heat source when the system is operating in the heating mode.
The hot water pump is a centrifugal pump for handling water at temperatures above 100 ºC. They are used for boiler feeding (see Boiler feed pump ), central heating (see Circulator pump ) and feed water circulation, and also as circulating pumps in nuclear plants (see Reactor pump ).
