How Efficient Is The EG4 Solar Hybrid Heat Pump?

In this video I break down how to calculate the COP on the EG4 solar hybrid heat pump, or any heat pump for that matter!

*Since filming this I have checked the COP at -1C/30F.. Any Guesses?

That's a really good explanation of Heat pump and electric heat.
I've been in the Hvac business for over 50 yrs and worked on about everything out there at one time or another. Except geothermal

Thanks for the great breakdown. I would like to know the COP as outside temperatures decrease.

Wow, that's a lot to digest for us layman. Thanks for the information and the video. Unfortunately still have not received my 2 units. Emailed and adked replied there is now no time frame on them. Kinda afraid they are stuck on the other side of the Panama Canal😢 Was really hoping to had them by now and installed and running. But out of my controll.... Jeff

We haven’t had much cold weather down here at 38° latitude. When we do, I’ll check my Fujitsu 33 seer 9000 BTU output.

Thanks for the good video. I'm curious to know if there is a way to have a DC-only solar with battery storage system, basically skipping the inversion step to deliver battery power to the heat pump.
