I have seen many posts mentioning radiant floor heat in different contexts, but I have a specific question that (I think) hasn't been addressed.
In a regular home, it's understood that turning down the thermostat in Winter saves money. The cost of heating is less because the temperature difference between indoor air and outdoor air is less, so there is less heat flow outward.
In a home with radiant heat flooring, not just in the basement, floors are warm, so air has to be cooler, or we'd overheat. With cooler air, the temperature difference between inside and outside would be less, so there's less heat loss, with no loss of comfort.
Now, what I'm wondering is, in the experience of folks who have lived in such a home for a winter or two, how much less is the air temp? It might be that people no longer measure it or look, since it's not really the heat control anymore.
