6.2 Applications
The ALPHAx circulator pump is designed for the circulation of
water in heating systems, domestic hot-water systems as well as

Cold-water systems are defined as systems where the ambient
temperature is higher than the temperature of the pumped liquid.
ALPHAx is the best choice for the following systems:
• underfloor heating systems
• one-pipe systems
• two-pipe systems.
ALPHAx is suitable for the following:
• Systems with constant or variable flows where you want to
optimise the setting of the pump duty point.
• Systems with variable flow-pipe temperature.
• Systems where you want automatic night setback.
• Balancing of domestic heating systems.
