I debated on heated flooring for the longest, and i live in Fort Worth, TX! While it doesn’t get that cold here, there are cold points! So having a furnace is a requirement.
I have gotten by with a ductless mini split in a few rooms.
I have the heating going just to keep everything comfy. I am not a fan of ductless heating though. It takes up wall space plus isn’t that powerful. I was always eyeing up my flooring plus thinking about something different, one year I got it in my head that it was the time. So I ripped up all my old rug plus was sold on a tile that hid dirt perfectly. I learn that heated flooring works especially well with tile. It keeps the heat the best, however also redoing the flooring is the best time to add a radiant heater. Other than that, it is only positive to this system. So I made the choice that it was the day for heated flooring. I had a Fort Worth heating corporation do it for me. They did the radiant furnace upgrade plus all I had to do was add tile board for them plus then the final tile overtop. The furnace is safely tucked away under the floors plus out of sight. I don’t definitely need to call for service or anything like that. What could they do with it sealed under the floors? I now have a quiet, energy smart, plus cleaner heater. I removed all my ductless furnaces to free up wall space… My rooms feel warmer, look better, plus my energy bills are so much nicer. It was a smart replace.
