This one is much better. It's the low temperature model, so this one works at negative 15 degrees compared to the yitahome which only works as low as 5 degrees. The Costway has an electric heater in it for subzero temperatures. This costway is also a 25 seer2 vs the the yitahome being a 19 seer2 meaning the Costway is much more energy efficient and cheaper to run.

Does it actually save money to use this as a heater compared to heating a whole floor via natural gas? At .15 cents per kw/h it seems like just using natural gas central heating for a ~2500 sq ft space is actually cheaper than using something like this to heat a smaller space like ~800 sq ft?

There are several factors that would impact specific costs: whether electricity is purchased at market rate or offset with solar, at mild temperatures air source heat pumps are very efficient in extreme cold they are less efficient, cooling abilities are also useful with increased summer temperatures. Also, there are significant health concerns with gas heaters when used unvented or for cooking.
If you live somewhere with inexpensive LP or natural gas and you already own the equipment this probably isn't a deal you'd be interested in, but for others watching their fossil fuel heating bills climb significantly the past several years this is a way to get off that escalator.

It's 230v system so it's way harder to install. 110v is much better and more straightforward

Way harder how?
For the 110V,you run the same one wire, you will still need to install a breaker (single pole instead of the two pole). I'm not sure how this is way harder

Is this any different from the models that were being clearanced at Home Depot recently? I suspect this has a higher seer rating?

For non-electricians 110 would be easier

How is it harder for non-electricians? For both 110v and 220v models you need a dedicated circuit. So, CoolChicken's response still applies for both voltages.

Right, the difference is really only where do you plug the white wire to and what kind of breaker you use.

Is this one worth the +$229 over their 17k btu model?
https://www.costway.com/17000-btu...white.html
its just for a 1,000 sq ft, 12ft tall wall shop AC in the summer, so I'm really only going to run it 4 months a year. Not worried about the power consumption difference since its about $8 more a month looking at the SEER rating.
The only difference I see is that the head unit is larger and outdoor unit is larger. I want app support. Would the larger head unit be better for a large, single room over the 17k for the $200 more? I have read not to oversize, too.
EDIT: I think I found what will make it worth it... 5yr vs 8yr warranty and 412CFM vs 765CFM airflow. Way more air flow and a longer warranty make it worth that. Its a bigger physical unit inside and outside, but the power savings will chip away at that.

It takes the same skills for both. The 110v model doesn't plug into the wall. It has to have the same amount of dedicated wiring to install and it still has to have an educated HVAC person to pull a vacuum on it. Lol, these don't plug into like a tv.

This is a great catch.

Does anyone happen to know if they still warranty if the installation isn't done by a certified HVAC professional?

if 110 vs 220 is way harder that individual should not be working with either.
