Heat Pump Efficiency Chart Your Terms Heat Most people and this includes those in the HVAC business when asked what the efficiency of a given heat pump is will tell you the SEER rating That s only part of the answer though Heat pumps you see work both ways Heat Pump Efficiency Chart energystar gov Certified Products Heating CoolingElectric air source heat pumps often used in moderate climates use the difference between outdoor air temperatures and indoor air temperatures to cool and heat your home ENERGY STAR certified heat pumps have higher ratings for seasonal energy efficiency ratio SEER energy efficiency ratio EER and heating seasonal performance factor
pump efficiency ratings d Several methods can be used to rate heat pump performance and efficiency COP Coefficient of Performance The Coefficient of Performance COP is the ratio of heat output to the amount of energy input for a heat pump COP can be expressed as COP h h h w 1 where Heat Pump Efficiency Chart waynewhitecoop pages EfficiencyHeat Pump Efficiency As we saw earlier a heat pump may use only one third as much energy as electric resistance heat electric furnace and baseboards for example during mild winter weather outdoor temperature about 45 degrees F pump effective temperature Unfortunately while many heat pumps are advertised as cold climate heat pumps few are equipped with features to make them perform better than conventional heat pumps when the temperatures drop and few manufacturers list the heat pump s effective temperature range
and cool heat pump systemsMany high efficiency heat pumps are equipped with a desuperheater which recovers waste heat from the heat pump s cooling mode and uses it to heat water A desuperheater equipped heat pump can heat water 2 to 3 times more efficiently than an ordinary electric water heater Heat Pump Efficiency Chart pump effective temperature Unfortunately while many heat pumps are advertised as cold climate heat pumps few are equipped with features to make them perform better than conventional heat pumps when the temperatures drop and few manufacturers list the heat pump s effective temperature range heat pump is a device that transfers heat energy from a source of heat to what is called a heat sink Heat pumps move thermal energy in the opposite direction of spontaneous heat transfer by absorbing heat from a cold space and releasing it to a warmer one Overview History Operating principles Applications Refrigerants Noise
