There is great discussion about heat pumps and DIY installation in the FAQ of the r/heatpumps community on reddit [reddit.com].
In most states, you do not need to be a licensed HVAC contractor to install one of these systems and can still do it "on the books" by pulling an Owner-Builder permit. For example in California: https://www.cslb.ca.gov/consumers...rvi
All heat pump systems have a factory charge that corresponds to a certain line length. You only need to add more refrigerant if you have longer lines than what the factory charge is good for. It looks like these systems are charged for a 16' length.
These systems are listed on NEEP Air Source Heat Pump [neep.org] and AHRI Certification [ahridirectory.org] directory. There is good additional documentation on those portals about the "actual" performance of these units at different temperatures.
If you live in a cold climate (below ~5F in the winter), you are going to want something that uses vapor injection technology [youtube.com]. Typically these systems are branded as "hyper heat" or "extreme heat" and work quite well in low temperatures.
Even though these systems are marketed as "low ambient", it doesn't appear to use vapor injection, rather relying on inefficient strip heaters. You can see this based on the performance noted on the NEEP website [neep.org] - for example the 9000 BTU unit falls to ~4000BTU heating capacity at -13F, and the COP falls from ~4 to ~1.5. This means that you are going to be using about 3x the electricity on cold winter days while having degraded performance.

Note: After checking, only the 12K BTU 230V unit is listed on the CEE list. It is also the only one that the Homedepot site lists as being "eligible for upto $2000 in rebates". So it seems if you want to be sure to qualify that is the only unit eligible as of now.

For a electric heater, it uses at most 1.5 x 10 = 15 kw for 10 hours, but it puts out only 5120 BTU

That being said, inverter heat pumps modulate their speed based on the heating demand that is needed. You aren't going to constantly need the max output over the entire 10 hr timeframe. Realistically you'll be at max for a little bit as the room heats up, and then the energy needed will drop substantially. Realistically you are probably looking at half the above energy or less since the effective energy you're using will be less over time. Hope that makes sense!
