I've seen some of the new Heat Pump technology out there. Been doing HVAC/R work for about 40 years. The old heat pumps never worked in the mid west. The cost of operation was high and the amount of heat they create was poor in low temps which require electric heaters to make up the difference - at a huge cost of electricity. Ground source helped greatly, but the these facts over all the years gave heat pumps a bad name. Very hard to convince anyone it is a better way to go verses natural gas or LP. Your specs look about the same as others I have seen. Another issue we have seen are new brands out there that are not known, which means no one knows how long they will be around to support their product. Even Carrier does not support some of their products made by other companies. Had a 7 year old heat pump for a computer room that they no longer support. With that said, It is not easy to move into the market as their is no guarantee you will be around long enough to support what you sell. Good luck in you venture.
