The PREMIUM Condens condensing boiler series includes boilers that operate with natural gas or propane, designed for central heating and household water heating. This boiler series brings top technology based in the latest trends in the field. The PREMIUM Condens boiler series consists of state-of-the-art components enabling active control of the combustion process. Customers can choose from two output series: 25 kW and 18 kW.

The boilers have stainless exchanger with cooled front burner wall. The new type of the gas valve in combination with the BLUEJET® burner provides a high level modulation. It allows for quality combustion even at low gas flow rate. The regulation ratio of this type of boiler is 1:10 and the minimum output starts at 1.8 kW. Moreover, the gas valve allows for optimisation of the combustion process and gas consumption preventing unnecessary heat losses. This series provides very quiet operation thanks to the multiphase fan.

Thanks to the broad range of output modulation, from 1.8 kW to 19.0 kW (or 2.65 – 24.9 kW), the PREMIUM Condens boiler series is suitable for use in low-energy buildings with low heat loss. The boilers can also be used only for heating household water, for which the maximum possible boiler heat output is available. Naturally, the boilers include equithermic regulation, including service setting of the required output range.

The OPTIMUM Condens gas condensing boiler series includes boilers that operate with natural gas or propane, designed for central heating and household water heating. There are currently two output series – 24 kW and newly 14 kW (sale starts in September 2018). This boiler series consists of components that offer an optimal price/performance ratio. Our customers can thus get high-quality, affordable boilers with a wide range of use.

The boiler consists of a condensing body with stainless exchanger, providing long service life, and a top-quality burner with high efficiency and ecological operation. The shape and dimensions of the exchanger tube plate limit the settlement of scale and sedimentation of the exchanger.

The boilers have built-in equithermic regulation for optimisation of the hot water temperature based on the outdoor temperature, thus reducing the cost of heating. The THERM 24 boilers have an increased output for the production of hot water and thus meet the high comfort demands of our current customers.

The advantages of the OPTIMUM Condens boilers also include the very quiet operation and small compact dimensions that allow for the installation of the boiler in the interior of family homes and flats. That makes the boilers an ideal source of heat for floor heating in such buildings.
