Also ground source heat pumps can have COPs in the 4-4.5 range and also keep that performance through a wide temperature range unlike air source heat pumps. Sad

Also ground source heat pumps can have COPs in the 4-4.5 range and also keep that performance through a wide temperature range unlike air source heat pumps. Sadly air source heat pumps COP really start to drop around 0F even with the new hyper heat models. Given that I would still probably prefer an air source heat pump over using heating oil or propane.
- pitaj 5y agoYeah the reason they stay in the higher range is because they're pumping from a source of higher temperature in the first place. They're also more effective at air conditioning because they're pumping into a cooler medium.
