Air-to-water vs Geothermal (How to make the right Heat Pump decision)

[@bwuepper439]

Most heat pumps in the US use R410, whose production is being phased out. Hard to find CO2 or propane based heat pumps. I have read that there are heat pumps that use air source until it drops too low than switches to ground source, but that will not be found in the US either. I definitely like the idea of a buffer tank and solar powered compressors, that's doable, except for the outrageous money being asked for a hot water tank. Thanks for the video.

Thank you very much for sharing! Do you remember where you read this?

@@NetZeroTech Here is one source: www.energy.gov/energysaver/geothermal-heat-pumps there are many others, BUT, the term hybrid is not used consistently, so you may have to read to make sure. And so just to make sure you understand me, the hybrid would use an air-source until temp gets too low, then switch to ground source. One other thing (it's probably not my idea, but I haven't found any other reference to it is this. Just after the compressor and condenser dump the heat into water, then send still warm refrigerant to an wall mount unit to dump remaining/residual heat to the room air. Allows for more heat to be extracted from the refrigerant because of the lower exhaust temp into room air. Should be more efficient.

Great video ❕️thanks for all the great information. Heat pumps are the best for the environment and your wallet

Thank you very much! 🙏 Glad you like it. I felt out of practice... Agreed on heat pumps. 🙂

And what about air to air? They are far simpler and more efficient to run. Air to water is not more efficient.

Hey, Thanks for leaving a comment. You can find info on air-source heat pumps in several of my videos: 1. kzbin.info/www/bejne/aXbbmaGKqr6BkJY, 2. kzbin.info/www/bejne/ommWeIJ5pciiqrssi=cGW-zhiGFy6GKoPq, and 3. kzbin.info/www/bejne/fKeaqZ6FmNqXa9ksi=D5ex9F-K724FcfbE. Air-to-water should be more efficient than air-source, especially with a water tank. Hope this helps, Katha

Air to Air 100% better.

Hi Paul, Would you mind sharing why you think so? Thanks, Katha
