For what it's worth, I checked the power consumption label on a 24,000 btu "inverter" mini-split system we have (just the outside unit). 1.9kw cooling. Then checked a Webasto all-in one unit, also 24k btu. They list average consumption of 2.01 kw.
Heating consumption 30k btu on the mini split is 2.7k, fyi.
For each you would have to add the amp draw of the pump in one case and the air handler in the other.
