What does "hydronic heating" refer to?

Hydronic heating refers specifically to a method of heating spaces through the circulation of water in pipes. This system typically involves a boiler that heats the water, which is then distributed through a network of pipes and radiators or underfloor heating elements. The efficiency of hydronic systems comes from their ability to maintain a steady temperature and provide consistent warmth throughout a space, making it a popular choice for both residential and commercial applications.

In contrast, heating through the circulation of air pertains to forced air systems commonly found in ducted heating systems. Electric coil heating involves the use of electrically heated wires or coils, typically in portable heaters or baseboards, and burning fuel directly refers to combustion-based heating methods, such as those used in traditional furnaces. These alternatives highlight the uniqueness of hydronic systems in utilizing water as a medium for heat transfer.
