DHW plate heat exchanger SB-251 floor-standing with two coils 10.5.02.002.02

Universal hot water heat exchanger with two coils

The SB-251 hot water heat exchanger is a floor-standing unit designed for efficient heating of domestic hot water. The design with two coils allows it to be connected to both a traditional central heating boiler and a solar installation, providing great flexibility and the possibility of saving energy. This solution is suitable for both single-family homes and commercial buildings where high performance and reliability are required.

Construction and application

The SB-251 heat exchanger is characterized by a solid construction and high quality workmanship. The tank is made of steel coated with a ceramic enamel, which provides effective protection against corrosion. Two coils with a surface area of 1.11 m² (lower) and 0.66 m² (upper) allow for efficient heat collection from various sources. The device has anti-corrosion protection in the form of a magnesium anode, which requires periodic inspection and replacement. PUR foam thermal insulation minimizes heat loss, maintaining a high water temperature for a long time.

Advantages for the installer and user

• Versatility: Possibility of connection to a central heating boiler and a solar installation – one device handles different heat sources.
• Durability: Enamel coating of the tank and magnesium anode provide long-term protection against corrosion. Each heat exchanger undergoes rigorous leak tests and quality control of enamel coatings.
• Efficiency: Two coils with a large surface area ensure fast and efficient water heating.
• Simple maintenance: Regular inspection of the magnesium anode allows maintaining high device efficiency for many years.
• Easy installation: Standard connections facilitate integration with the existing hydraulic installation – important for installers looking for solutions to speed up work.
• Energy saving: Good thermal insulation minimizes heat loss, reducing operating costs – important for both end users and installation companies advising on optimal solutions.

The SB-251 heat exchanger has a capacity of 251 liters, the surface area of the lower coil is 1.11 m², the upper one is 0.66 m², the rated pressure of the tank and coil is 1.0 MPa, and the power of the lower/upper coil is 33/19.5 kW, respectively.

Additional expansion options include the optional installation of an electric heating element, which will provide access to hot water even in the event of a failure of the main heat source. Remember to entrust the installation to a certified installer to ensure proper operation of the device and safety of use.
