Product description

Easy to control a fireplace with a water jacket

Euroster 11K is a programmable controller dedicated to home heating installations with a water jacketed fireplace. It controls circulation pumps and an air damper and can work in one of three installation systems: central heating system supply through a plate heat exchanger, central heating system supply via a heat buffer and charging the hot utility water tank and central heating circuit supply via a plate heat exchanger. The controller is equipped with Anti Stop anti-stagnation pump protection system, which prevents seizing of the unused pump impeller in water-jacketed fireplaces. After the end of the heating season, the system automatically starts the pump every two weeks for 30 seconds (for the system to work after the season, the controller should be left turned on).



  • The universal controller designed for installing a fireplace with a water jacket, has the following outputs:
    • air damper
    • plate heat exchanger circulation water pump
    • central heating water pump or buffer tank charging
    • DHW tank loading water pump
    • universal, voltage-free, designed to switch on an additional heat source (e.g. gas boiler)
  • The ability to work in one of three modes:
    • central heating supply through a plate heat exchanger
    • powering central heating systems through a heat buffer
    • charging the hot utility water tank and supplying central heating circuits through a plate heat exchanger
  • Possibility to automatically switch on an additional heat source (e.g. gas boiler)
  • Regulation of the combustion process by damper control based on measured temperatures and information from the room regulator
  • The Anti-Stop system, which starts the central heating circulation pump (outside the heating season) for approx. 30 seconds
