Floor-standing condensing boiler with integrated stratified buffer tank 150 l

This solution combines a heating boiler and a domestic hot water (DHW) tank in a single, compact unit. It does not require an additional tank – installation is simpler, and space in the boiler room is saved. It is ideal for single-family homes where constant access to a large volume of DHW is important without the need to install separate components.

An efficiency of 108% (Hi) is achieved thanks to condensing technology, which recovers heat from water vapor in the flue gases. In practice, this means lower gas bills – compared to conventional boilers, savings can reach up to 30%. In DHW preparation mode, the efficiency is 100%, confirming the system's operational effectiveness.

The 150.8 l stratified tank ensures an initial output of 379 l/10 min at a temperature difference of 30 K. This means you can simultaneously take a shower, fill a bathtub, and use the kitchen tap – there is no drop in temperature or "pause" for reheating. The continuous output is 976 l/h, allowing the system to handle even multiple DHW uses throughout the day.

The rated power of 30 kW (50–30°C) and the maximum power during DHW heating – 34 kW – allow for efficient heating of homes up to approx. 500 m². The power modulation range from 6.6 to 32.5 kW enables the boiler to adapt its operation to the actual load – it does not run at full power when not needed.

The casing made of stainless steel ensures durability and corrosion resistance. Built-in expansion vessels (4–8 l for heating, 15 l for DHW) and a circulation pump eliminate the need to install additional components. The boiler complies with the ErP 2015 directive and is intended exclusively for operation in a closed system.

Dimensions: height 1640 mm, width 599 mm, depth 693 mm – allowing installation even in limited spaces. The weight of the empty unit is 131 kg, and when filled – up to 287 kg. This is not equipment for manual handling – it requires appropriate mounting equipment.

All this operates silently: the sound power level is 49 dB(A), which is comparable to the level of conversation in a room.
