Mini-split heating efficiency – Floor/ceiling mounted vs concealed duct
Comparing efficiencies between floor mounted and concealed duct mini splits. Using 9k btu H2i Mitsubishi units for an apples-apples comparison.
Plugging the numbers into a BEopt sim shows a 28% increase in energy usage yearly for the concealed duct version.
* Is the difference from the outdoor unit (M series vs S series)?
* Will the difference in spec and simulation translate into a real-life difference in energy use?
