I’ve been wondering lately how small one of the indoor inverter heads could be scaled down to. Specifically, whether it could approach the footprint of a ducted heating outlet (with most of it under the floor). It seems like it would be more efficient to run coolant lines to the heads rather than blowing all that air through ducts as well as making it easier to have separate temp zones in the house. Does anyone know what the physical limitations are?
