My property has uninsulated galvanised steel ducting in the walls that I thought about using for a new heating system.
Main problem would be heat loss as ducted aircon systems use flexible insulated ducting.
Maybe could use that inside the steel stuff but that’s when I lost interest in the retrofit.
Electric warm air is history.
Modern storage space heaters seem the logical and easier replacement.0 -

Actually most of the ducting (2m) is in the warm air heater cupboard. It does get very warm in there but that’s not where I want the heat.
An indoor aircon unit could easily fit in there which would then connect to the outdoor one.
An adapter would be needed to fit the 4x8 inch ducting to the unit.
Could work but probably an expensive install and not as maintenance free as storage heaters.
