The two have different meanings: floor heating refers to ground radiant heating. Plumbing refers to the use of hot water circulation for heating.
Different types are included: floor heating can be divided into two types: water floor heating and electric floor heating. In addition to water floor heating, water heating also contains radiators.
The medium of heat dissipation is different: floor heating is to heat the ground through hot water or heating cables, dissipate heat from bottom to top, and increase the temperature of the room. Plumbing is just a heating effect that increases the temperature of the entire room by dissipating heat through the circulation of hot water.
