Pretty sure mini splits are significantly more efficient today, with SCOP of above 5, so that seems unlikely?

- fifteenforty 4y agoThis unit runs at about 5
- rootusrootus 4y agoI recently replaced my [central, ducted] heat pump, and the new one is rated with a 4.981 SCOP. It's fairly efficient, but not the most efficient on the market.
- fifteenforty 4y ago-40% for the duct heat loss
- rootusrootus 4y agoThat seems kind of high for insulated ducts, where does that number com from?
- fifteenforty 4y agoUS energy.gov
- dahfizz 4y agoIt would be nice to actually link the source[1] (PDF). The stat is that you lose between 25-40% efficiency for "typical" existing installations. The document goes on to explain that an insulated duct which doesn't leak doesn't have this kind of efficiency loss.
