The tech costs more than conventional options upfront, but federal tax credits, new 120V models and strong savings have made them more appealing than ever.
at my parents house the is a 14kw heat pump that does heating and water and it’s not an industrial heat pump.
you can get them from daikin, but they need three phase ac.
I would call anything that needs 3-phase to be “industrial”. The number of residences with 3-phase would be in the low hundredths of a percent of homes.
German 3-phase is at 400V, there is no such thing as 2-phase (you’re probably thinking of split phase 110+110 as in NA). So I’d be practically certain your parents have single phase 230V.

3-phase 230V 16A is standard here. but you can get up to 30A if the wiring allows it. I’ve never seen a house with only 1 or 2-phase.

between neutral it’s 230V.Between two phases it’s 400V.
