Efficiency key to Toyesi Heat Pumps.

Toyesi heat pumps are built to have an average COP of 5 between 15C to 18C ambient conditions.

Some companies use EER, SEER or HSPF as references for heat pumps or chillers. Although useful as a guide these values are based around the use of BTUs rather than kW as their energy rating systems.

For Estimation Purposes.

COP = Energy out (kW) / Energy used (kW)
SEER = EER ÷ 0.9
SEER = COP x 3.792
EER = COP x 3.413
HSPF = COP x 3.792

Brief Term Explanation:

COP ~ Coefficient of Performance – Usually used in heating, but can be used in cooling applications.
EER ~ Energy Efficiency Ratio – Usually only used in cooling applications
SEER ~ Seasonal Energy Efficiency Ratio – This is used as a typical seasonal performance in a given location. So SEER values are usually only project based values.
HSPF ~ Heating Seasonal Performance Factor ~ basically the same as SEER but for heating only. So HSPF values are usually only project based values.

For Example:

a COP of 5 is equivalent to an EER of 17, a HSPF or SEER of around 19

Toyesi Heat pumps are renown for their superior efficiency over other forms and types of Heat Pumps. With typical COPs of 4 to 8, depending on Ambient and water temperatures and conditions. Meaning that our systems offer performances equal to most inverter models and well above other standard heat pump models.

When directly comparing heat pumps, make sure you look at the ratings of the heat pumps at similar water and ambient conditions. Many brands list COPs at 27C water and 25C ambient conditions, where there is actually very little heating to be done.  If Toyesi listed COPs at this level, you would see COPs of 7 to 8. However, this does not truly reflect an overall average performance across most of the year. By sizing heat pumps at 15C to 18C ambient conditions will give you a good average guide, for a year long, performance of your heat pump.
