Are minisplits enough, or do we need floor heating too?
We are retrofitting an old bungalow in Toronto. It will be air-tight with above-code R-values. We are going all-electric with ductless cooling and heating. For heating, would mini-splits be sufficient? Or do we need backup heating like hydronic floors?
The finished house will have two floors, about 3000 sq. ft. plus basement. Ventilation will be HRV.
