For us, sort of. Only the master of the house has cold feet here; the ladies already go out on the terrace barefoot in winter. I find underfloor heating generally unpleasant. My husband did not want a water-cooled heating system. We wanted a passive house; only air heat pumps did not convince us. So underfloor heating it was. Then, during the planning phase, the offer came to install an experimental system, which simply put is on one side an air-water heat pump, but on the other side distributes the heat via the ventilation system similar to an air heat pump. That got rid of the underfloor heating and has not been regretted. The tiles in the bathroom are relatively warm because the distribution goes through for the upper floor and the system is located in the room below.
