STIEBEL ELTRON STE HSTP 300 Floor-Standing Indirect Hot Water Cylinder 300L Two-Circuit/Single-Circuit Operation 071267

The STIEBEL ELTRON STE HSTP 300 is a high-quality floor-standing indirect hot water cylinder with a capacity of 300 litres, designed for efficient domestic hot water supply in residential and commercial applications. It supports both two-circuit and single-circuit operation, offering flexibility for various heating systems.

Advantages

Energy efficiency class B ensures low standing losses of only 1.8 kWh/24h. The high-quality PU rigid foam insulation minimises heat loss, while the enamelled steel tank with magnesium anode provides reliable corrosion protection. The large heat exchanger surface area of 1.8 m² enables fast heat-up times.

Suitable for

• Domestic hot water supply in single-family homes, multi-family buildings, and commercial premises
• Integration with solar thermal systems, heat pumps, or conventional boilers
• Two-circuit or single-circuit heating systems
