Radiant heating
Underfloor radiant heating systems can be installed as either wet or dry systems. Wet systems are laid down and then concrete is poured over them. Concrete floors hold heat very well, but can take a long time to absorb the heat. Dry systems run in open air space between the foundation and the floor, but can be less efficient because they have to heat the air too. However, dry systems are much easier to reach if the system breaks or leaks.
