I'm planning to use this unit for water-to-water, as you've described in your first machine. my plan is to hook one side into my hydronic floor and the other side into either solar panels or loops in ground. Both the solar panels and the loops in the ground I plan on building later on. Since I can't be on-site much during construction, and we've had a lot of rain lately, I'm working on this particular part of it for now.
I'm still looking around for other donors to use for this project, in case this one doesn't work out. I have a larger 230v 18000 btu unit that someone gave to me and doesn't work. I haven't dug into it as of yet. but from reading your previous posts on here, I was trying to use something smaller to learn/test this initially.
the hydronic floor part of our house is about 1000 sq ft.
it's a 2-story house, but I only have this in the first floor.
I've calculated the heat load of my entire house to be in the area of around 18000-22000 btu, with the added insulation we'll be installing.
