Modern boiler with a larger exchanger
WENUS stands out with its large surface heat exchanger, which ensures even better heat transfer. The improved design contributes to better heat absorption and reduces its losses thanks to the use of a double-return smoke path and optimal arrangement of fire tubes. WENUS boilers with upper combustion are commonly installed in single-family houses and multi-family buildings, garages, commercial facilities and other types of buildings.
Rapid heating of indoor spaces
WENUS boilers provide the highest output using hard coal, coke, or wood. Burning proceeds relatively quickly, and in no time the boiler achieves high heat output. Additionally, a recycled air throttle enhances the burning process. Thanks to low heat dissipation, WENUS boilers have good thermal efficiency, reaching even 82%.
The combination of a traditional heating boiler with modern solutions facilitates the operation of the unit. The boiler is designed to accept a PID algorythm control module, which permits easy setting of parameters for optimum performance. Also, with such a control unit the user needs only to replenish the fuel and remove the ash.
The enlarged burning chamber provides for easy fuel charging. Its dimensions ensure longer operation because at one time the user replenishes more fuel, so the time in between is longer. WENUS boilers are made with durable sheet steel, which is resistant to high temperatures.
Large combustion chamber.
Designed for self-assembly of the Control Kit, which is available at an extra charge.
Combustion is controlled by means of an automatic draught regulator* or manually (*as an option at extra charge).
High combustion efficiency, up to 82%.
Certified boiler plates P265GH.
Quick and effective ash removal thanks to a cast iron, mobile grate.
60-month warranty for leak tightness of the water jacket.
24-month warranty for service life and efficient operation.
Automatic, by means of a draught regulator.
Manual, by means of a screw adjusting the position of the flap in the bottom door.
Automatic, by means of an electronic controller (ZS-01).

A draught regulator in solid-fuel boilers is a thermostatically operated device for controlling water temperature in the boiler.
A thermostatic head of the regulator monitors the water temperature in the boiler and via levers and a chain actuates a flap to increase or reduce the airflow into the hearth.
The ST-81zPID controller is in charge of a continuous regulation of the induced air inflow and the control of the central heating and utility water pumps.
It is fitted with boiler temperature and exhaust gas sensors. It is made from high quality materials, which are resistant to high and low temperatures.
