Heat Pumps - Performance and Efficiency Ratin

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

Finding Balance - Heat Pump Heating Load vs. Capaci

For example, if you're paying a marginal electric rate of $0.1143, then the price per therm at 1 COP is $3.35. Now, divide the electric cost per therm at 1 COP by your furnace's operating cost -- $3.35 / $1.15 = 2.9 COP. Since a heat pump's COP drops with the outside temperature, we need to know at what temperature it will operate at 2.9 COP.

coefficient of performance - wikiped

Coefficient of performance - Wikiped

The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required. Higher COPs equate to lower operating costs. The COP usually exceeds 1, especially in heat pumps, because, instead of just converting work to heat (which, if 100% efficient, would be a COP of 1), it pumps ...

For example, the calculation of the total annual NOx emissions for an 800 hp boiler operating 24 hours/day, 365 days/year and having a NOx level of 110 ppm would be as follows. Emission Factor = 0.13 lb/MMBtu (110 ppm = 0.13 lb/MMBtu) Boiler Input = 33.5 MMBtu/hr (Based on 80% Efficiency)

Compare Heat Pump to Condensing Boiler |

Therefore, if an air-source (or ground-source) heat pump has a CoP of greater than 2.24, it will release less carbon emmissions than a condensing boiler.. A similar calculation can be carried out on the cost benefits of a heat pump over a condensing boiler, and (at UK prices where gas is less than half the price of electricity per kWh), the break-even CoP is also around 2.2-2.3, i.e. a heat ...
