Circulation pumps for heating and cooling

Circulation pumps for heating and cooling

Circulation pumps are designed to move water in closed hydronic heating and cooling systems. They provide a constant flow of hot or cooled water between the source (boiler, heat pump, chiller) and the consumers - radiators, underfloor heating, fan coils and other heat exchangers.

Unlike pumps that overcome great heights, circulation pumps primarily overcome hydraulic resistance in pipelines, radiators and heat exchangers, maintaining an even temperature distribution throughout the system.

Applications of circulation pumps

• Heating systems with boiler, heat pump or radiators.
• Underfloor and wall heating in residential and public buildings.
• Cooling systems with chillers and fan coils.
• Domestic hot water recirculation for faster access to hot water.
• Hydronic air conditioning installations in commercial and industrial facilities.

How to choose a circulation pump

For proper selection, data is required on the type of system (heating, cooling, recirculation), the heat load or flow rate, the hydraulic resistance of the system, the operating temperature, the type of heat carrier and the control requirements (fixed speed, variable speed, timer, thermostat).

Modern variable speed circulation pumps automatically adapt the flow to the actual system demand and can significantly reduce electricity consumption compared to older fixed speed models.
