Hydronics is the term describing the use of water as a heat-transfer medium in heating systems, and a cooling-transfer medium in cooling systems.
Types of hydronic systems:
• heated water
• chilled water
Hydronic systems may further be classified by factors such as:
• Flow (forced/gravity)
• Temperature (low/high)
• Pressure (low/high)
• Piping arrangement (e.g. 1- or 2-pipe system)
• Pumping arrangement
Grundfos meets the pumping requirements for hydronic heating systems, for example hydronic radiant floor heating.
