Hydronic systems are heating and cooling systems that use water as a heat transfer medium. They circulate hot or cold water through pipes to radiators, baseboards, or underfloor heating elements, effectively warming or cooling spaces. This method is energy-efficient and can provide consistent temperatures throughout a building. These systems can be powered by various sources, including boilers, heat pumps, or solar thermal systems. Hydronic systems are often used in residential and commercial buildings for their ability to maintain comfort while reducing energy consumption. They can also be integrated with smart home technology for enhanced control and efficiency.
