Not surprisingly, installation procedures and marketing are different overseas.
After World War II there were basically only two widely practiced ways of heating dwellings, either by a stove in each room or by central heating with steam or hot water passing through radiators. In some regions they also used night-storage electric heaters taking advantage of the cheaper rates for power at night.
By the early-1970s, however, underfloor heating (ufh) with hot water started spreading from Switzerland, Austria and Germany whereas electrical systems (foils in Spain, cables elsewhere) never got far beyond a dismal 5 percent market share.
