Hi All, as requested by here are some quick screen grabs of three different heat pumps and the real efficiencies they run at. In this case the SPF correlates to COP, these heat pumps have a built in flow meter and a built in electric meter which puts this information together for the user!
On example 1 we can see COP 4.15 for heating and a COP 3.97 for HW, example 2 we can see 5.36 COP for heating and a 4.89 COP for HW and example 3 we see COP 5.88 for heating and 4.84 COP for HW. These are obviously an average for the total lifetime of the heat pumps, I believe example 1 was installed in 2019 and is part of a cascade. Example 2 was installed in 2020 and example 3 was 2021. Happy to share more data 📊 and let you speak to clients directly if you’d like Ian?
So what do we think of these real life Air Source Heat pumps examples?
