Description

The automatic pellet boiler Defro Smart Ekopell features a reinforced construction and a built-in cooling coil enabling safe operation in a closed-loop system. The pellet burner is made of the highest quality materials, has an automatic cleaning function and two igniters as standard (Twin Spark System). The boiler is equipped with an innovative controller with a color touch display controlling 6 pumps. It also has a high efficiency of up to 90%. The boiler tank has a fuel reserve sensor; when the fuel level is minimal, the boiler operation is stopped, and after refueling, ignition occurs automatically.

  • innovative ADAPTIVE Control steering using a turbine flow meter ensuring optimal selection of fan and feeder operating parameters;
  • boiler ignition and shutdown occurs automatically;
  • igniter control;
  • control of blower fan, exhaust fan and feeder;
  • control of CH, DHW, additional and two valve pumps;
  • control of additional device;
  • control of two mixing valves;
  • fuel level sensor and fuel consumption measurement – protects against complete depletion of the fuel supply system;
  • option to set daily boiler operation;
  • weekly control of boiler, DHW and valve temperatures;
  • weather control;
  • internet module (included) allows you to change boiler operating and service parameters (access to user and service menus, ability to remotely ignite and shut down the boiler);
