'SCOP is a new methodology that gives a better indication of expected real-life performance, using COP can be considered using the "old" scale. Seasonal efficiency gives an indication on how efficiently a heat pump operates over an entire cooling or heating season.'

This is factory produced test data which is no more relevant to an individual site than the CoP.

When I select a system I look at the performance at the lowest, realistic ambient temperatures, the correct water temperatures and then look at the other ambients that the system will generally be operating at 90% of the time. This data is freely available.

SCOP is taken at water temperatures of 35 DegC and 55 DegC to comply with EN14825 so could be used to compare manufacturers but is not that accurate for individual projects.

Hi Everyone,

I came across a formula for the calculation of SCOP, but can't remember where I found it.

As Bobbt9866 states the actual SCOP achieved will vary from site to site, though it should allow comparison of different systems to an extent.
