Wide possibilities

Our boilers are characterized by wide power modulation in the range of 2.3 – 24 KW. In selected models, the minimum boiler power is only 2.3 kW, which is one of the lowest parameters on the market. This coefficient allows the use of our boilers in a wide range of facilities – from small apartments to segments or large single-family houses. Also noteworthy is the efficiency of our devices, which is over 107% – this value means that we can be sure of economic and ecological gas combustion. We offer two dual-function models with class L hot water plate exchangers (hot water heating – 11l/min at ΔT 30°C).

For houses with a large number of household members, we have prepared an offer of single-function gas boilers adapted to work with capacitive hot water heaters. Our offer of gas boilers will meet the expectations of even the most demanding customers. We have boilers in various colors that can fit into even the most demanding boiler rooms.

eModul application

The eModul application is an ideal solution for people who live busy lives, often work different hours and lack time for household chores. It has long been known that editing the operating parameters of a heating device depending on your own activities significantly reduces heating bills. Thanks to the application, you can perform the same activities both at home and in the office, all to achieve maximum comfort and efficiency with the lowest possible energy consumption. Using device operating schedules, you can vary the temperature during the day in different time intervals using a laptop, tablet or smartphone, from anywhere on Earth. Using the eModul application, you can lower the temperature at any time if you forgot to do it before going to work or on your way on vacation.
