Stationary combined cast iron boilers

The new generation stationary gas boiler with which we started our production is popular in many countries and has won several awards. Long-term improvement of our know-how makes this boiler a high-quality and reliable heat source. The quality construction of the cast iron body is equipped with the latest technology to achieve the best possible ratio of high efficiency and low cost. The boiler will find its place in the reliable heating of your houses, flats, but also industrial buildings.

Where to buy

GAS stationary boiler and versions

We have prepared for you a choice of 5 modifications of the stationary combined boiler ATTACK with an output of 12 – 30 kW. The stationary boiler is fully automatically controlled by a boiler control or a room controller with the possibility of connecting a superior control. In the table we offer you a summary of what makes the versions different and what they can offer you. It has been designed with an emphasis on ease of use, low maintenance and long life with reliable performance. So everyone can control it. The boiler will certainly not disturb you with its operation because its operation achieves very low noise. You simply connect the flue to the chimney and you can start using it.

Gas Stationary boiler and output regulation

We offer you wide variability in the regulation of the output of our stationary boilers.

The basic version EKO provide one-stage regulation which the boiler works at full output in.

The more advanced versions of the PLQ and KLQ COMBI boilers already offer a simple two-stage control which the full output can be damped to 80% by simply switching the switch while maintaining the same efficiency in.

With the E COMBI boiler you will be able to regulate the output similarly but the regulation is performed automatically, 7 ° C before the required temperature is reached so you don’t have to worry about it.

Indirect heated storage tank with the volume from 40-275 l

Performance enhancements

If you need more power than stationary boilers provide, you don’t have to look for complex and expensive solutions that may not be effective at all. With stationary combined boilers, we offer you the opportunity to easily cascad several boilers at once for higher thermal performance. The stationary boiler enjoys popularity in up to 40 countries around the world.

Wide range of D.H.W. storage tanks

For stationary gas boilers, we have prepared a wide selection of indirectly heated storage tanks for the preparation of domestic hot water. You can choose from a wide range of tanks with different functions, one or two exchangers, location, and volume from 40 – 275 liters.
