Coefficient of
Performance
The coefficient of performance,
or COP, of a heat pump is the ratio of the
output heat to the input supplied. An air
source heat pump operating at COP of 3.4,
will provide 3.4kW of heat output for every
1kW of unit input (energy consumed).
Key Benefits of
Air Source Heat Pumps
The Air Source Heat Pump
typically draws approximately 1/3 to 1/4
of the electricity of a standard Electrical
Heating system for the same amount of heating,
reducing utility bills and greenhouse gas
emissions accordingly.
This typical efficiency
of 300%-400% compares to 100% for a resistance
heater and 70-95% for a fuelpowered boiler.
Few moving parts, reducing
maintenance requirements. As an electric
system, no flammable or potentially asphyxiating
fuel is used at the point of heating, reducing
the potential danger to users, and removing
the need to obtain gas or fuel supplies
(except for electricity). May be used to
heat air, or water, as the need arises.
In some installations the same system may
be used as a cooler, as well as a heater. |
