Condensing Boiler Series and New Products
News | 21. 9. 2018
The upcoming heating season will bring some novelties in the THERM condensing boiler series. In response to the modern trends of heating, we have prepared two new boiler series, which we have divided into product series together with the known and used types, differing in design and adaptation. Each of the series brings specific advantages, which we would like to introduce to you.
The THERM condensing boilers are now divided into three product series:



PREMIUM Condens Series
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 THERM 18 boiler series with its output range directly replaces the THERM 14 KDx.A and THERM 17 KDx.A boiler series, the production of which has been terminated.

OPTIMUM Condens Series
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.

CLASSIC Condens Series
The CLASSIC Condens gas condensing boiler series includes boilers that operate with natural gas or propane, designed for central heating and household water heating. We are currently offering three output series – 28 kW, 45 kW and 90 kW. These are condensing boilers with an attested and reliable design for heating larger objects. This type of boilers is also ideal for condensing cascade boiler rooms for heating residential homes, schools, medical facilities, accommodation facilities, or industrial objects.
The boiler consists of a condensing body with stainless exchanger and other quality components that provide safe operation at low cost. 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 28 boiler series provides a very comfortable supply of hot water, whether using the THERM 28 KDC.A plate heat exchanger, or a storage tank – THERM 28 KDZ.A (with a connection to an external tank), THERM 28 KDZ5.A (integrated 55 litre tank) and THERM 28 KDZ10.A (integrated 100 litre tank). The THERM 45 KD.A and THERM 90 KD.A types allow for water heating in an external tank using an external three-way valve.
