Buffer tank with hydraulic coupling for solar installation Roth Thermotank Quadroline TQ-S 850 l for heat pumps 1115009993

Buffer tank for solar and heat pump installations

This Roth Thermotank Quadroline TQ-S 850 l buffer tank is an advanced solution for storing heat in solar installations and those working with heat pumps. Its construction, based on an innovative combination of PE-RT plastic with an aluminum layer and fiberglass reinforcement, ensures exceptional durability and corrosion resistance – eliminating the need for a magnesium anode. The tank is designed for efficient storage of thermal energy, which translates to optimized operation of the entire heating system.

Construction and application

Made of high-quality PE-RT plastic, the tank is characterized by its light weight, making it easy to transport and install, even in difficult conditions. The integrated stratified charging system allows for optimal temperature distribution in the tank, increasing its efficiency. Two immersion sleeves allow connection of up to four temperature sensors, enabling precise control of the installation parameters. The tank is ideal for heating and domestic hot water systems (although it is not intended for direct DHW heating). Its capacity of 850 liters provides thermal comfort even in large buildings.

Key features and benefits

• Lightweight construction: Facilitates transport and installation, reducing installation costs.
• Corrosion resistance: PE-RT material eliminates the risk of corrosion, extending the life of the device and reducing operating costs.
• High efficiency: Integrated stratified charging system optimizes temperature distribution, increasing heat storage efficiency.
• Versatility: Compatible with various heat sources – solid fuel, oil boilers, heat pumps and gas or electric heaters.
• Monitoring capability: Two immersion sleeves allow connection of up to four temperature sensors for precise system control.
• Safety: Maximum working pressure of 3 bar and temperature resistance up to 90°C ensure safe operation.
• Durable insulation: Removable hard EPS foam insulation minimizes heat loss (although the tank itself does not have insulation).
• Ready for sensor mounting: Four sleeves for temperature sensors (internal diameter 8 mm) facilitate integration with the control system.

The tank capacity is 850 liters, the maximum operating temperature is 90°C, and the maximum working pressure is 3 bar. It is equipped with two immersion tubes and four connections for temperature sensors. The connection size is 1 1/4 inch, the height is 1965 mm and the diameter is 970 mm.

The Roth Thermotank Quadroline TQ-S tank is an investment in thermal comfort and energy savings – a solution appreciated by professionals and end users for its reliability and efficiency.
