Domestic hot water recirculation pumps

Domestic hot water recirculation pumps

Domestic hot water recirculation pumps are installed in the hot water system between the boiler (or other hot water source) and the most distant points of consumption. They move the hot water in a closed loop so that it does not cool down in the pipes, but is available almost immediately when the tap is opened.

Without recirculation, the cooled water in the pipes must be drained before it reaches the hot water from the water heater. With a recirculation pump, this cooled water is returned to the water heater for reheating, leaving hot water in the pipes, ready for use.

Applications of recirculation pumps

• Residential houses and apartments with a large distance between the water heater and the taps.
• Hotels, boarding houses and other facilities with many bathrooms and long pipe runs.
• Public buildings, offices and commercial premises in need of fast hot water.
• Systems with a boiler, solar hot water system or heat pump for domestic hot water.

Advantages of recirculation pumps

• Quick access to hot water in every tap and shower, without long waits.
• Reducing water consumption, as cold water is not drained until warm water appears.
• Higher comfort in large sites and buildings with remote bathrooms and kitchens.
• Possibility of operation in continuous mode or on demand (with button, timer or sensor).

How to choose a recirculation pump

For proper selection, data is needed on the type of system (boiler, solar system, heat pump), the location of the boiler and the most distant points, the length and diameter of the pipes, the desired operating mode (continuous, on timer, on demand) and the energy efficiency requirements.
