Answer: baseboard heaters exist and are economical.
Yes, alongside traditional baseboards (in tiles, wood or PVC), there are heated baseboards. Moreover, the heating by baseboards is of much better quality than that by radiators, because the heat is distributed harmoniously throughout the room in a more efficient way. The baseboards heat as well with electricity as with a central heating system with hot water. They are easy to install, even for an individual beginner, and above all, there is no risk of burns or fire, so you can install furniture nearby without problem! Another advantage, baseboard heaters occupy less space than a network of radiators, and their installation is less expensive than that of a heated floor. The icing on the cake, they consume around 30% less energy than a traditional heating system!
