Heating kit systems


Circulators integrated in kit systems for heat distribution

Grundfos supplies heating kit circulators that are customised for heat distribution. Our typically side-mounted circulators are self-controlled, stand-alone and react on changing flow demand from the heat consumers, such as from radiators and underfloor heating circuits. We customise the hydraulics to match the required system performance and efficiency.

Grundfos circulators for heating kits customised for heat distribution:

  • All kinds of boilers and other heating appliances
  • Buffer tanks or hydraulic separators
  • District heating
  • With or without heat exchanger or mixing valve
  • Combined space heating and cooling systems
  • Decentralised DHW production

Grundfos circulators for heating kits are characterised by:

  • Small integrated circulator design
  • Reduced size and production cost of the module
  • No ambient temperature constraints (EN 60335)
    The resilience to heat enhances the possibilities for system integration enormously. Grundfos Circulators are built for up to 70°C ambient temperature
  • Efficient performance

This range contains asynchronous and high efficiency ECM circulators. High Efficiency Circulators use up to 87 % electrical power than conventional constant-speed circulators and up to 68 % than conventional speed-controlled circulators and already fulfil European Ecodesign requirements in 2015, EEI ≤ 0.23, EN16297/3 or -/2

Meets different capacity demand for boiler systems

Circulators for varying demands with different use and power consumption for either single family houses or heating kits installed in commercial buildings. The Medium circulator range is a well-fitting platform to benefit larger sized kit systems with the product efficiency that is really needed

Performance Control
Either externally controlled by digital pulse-width modulation (PWM) low-voltage signal or internally controlled in constant pressure, proportional pressure or constant speed mode, defined by the means of a smart user interface or factory presetting.
