PelTec-WiFI-readySteel hot water boilers Peltec are engineered for wood pellet firing. In the boiler is installed the burner for wood pellet firing with the automatic firing and automatic self-cleaning function which enables the reliable operation also with the low quality wood pellets. The function of the automatic cleaning flue gas tubes provides the unifying exchange of the heat and high and unifying level of boiler efficiency. Multifunctional digital boiler controller in a basic version offers the possibility of modulating boiler operation and control the level of pellets in the tank. Inbuilt return flow protection ensures correct boiler operation also at the lower return flow temperatures. PelTec lambda is boiler version with factory inbuilt lambda probe for further optimization of the combustion process. The pellet tank is the integral part of the boiler. The boiler is delivered in sections for easier transport into the boiler room.

  • High boiler efficiency and low maintenance requirements.
  • Low emission of harmful compounds in the flue gases
  • Modulating operation of the boiler (30% -100%).
  • Automatic cleaning of the burner grid and flue passages.
  • Flue gas temperature sensor and level sensor pellets in the tank.
  • Integrated return flow protection with 4way mixing valve with actuator for direct heating or buffer (storage) tank systems (in systems with several heating circuits required hydraulic crossover).
  • Multifunctional digital control with color touch screen display regulates the boiler function and can direct 2 pumps (e.g. one direct heating circuit and a plumbing circuit…).
  • Emptying the ash box, after having spent 2-3 pellet tanks (400-600kg).
  • Additional equipment: module for directing 2 (max 8) heating circuits according to the outdoor temperature, room corrector, GSM alert for boiler and pellet storage status, automatic pellet storage filling, controlling boiler functions by an outer controller, cascade manager.
  • PelTec lambda is a version of PelTec with factory inbuilt lambda probe, PelTec-lambda.
  • The boilers are tested and certified  in accordance with the standard EN303-5:2012. They satisfy the class 5 and are manufactured in accordance with the standard ISO 9001 and ISO 14001.
