Does a ductless mini split actually work as primary heat in winter or just cooling
Moved into a 1960s ranch last year with the original baseboard electric heat. I’m thinking about doing one room at a time, starting with the back bedroom. It’s about 280 square feet with two exterior walls, and the double-pane windows were replaced around ten years ago. I’m in zone 5b on the Colorado Front Range, where winters regularly get into the single digits and sometimes below zero.
The baseboards run almost constantly from November through March, and the room still feels cold near the exterior walls. I keep hearing that a mini split heat pump can handle heating, but I’m having a hard time believing a ductless unit can really replace the baseboards when it’s 5 degrees outside. What has everyone’s actual experience been using a mini split as the main heat source through a real winter?
