Central heating buffer tank with hydraulic coupling Roth Thermotank Quadroline TQ-T 325 l for heat pumps 1115009463

Buffer tank for central heating with hydraulic coupling – optimizing heat pump operation

This Roth Thermotank Quadroline TQ-T buffer tank with a capacity of 325 liters is designed to work with heat pumps, but can also be used in systems with other heat sources. Its construction allows for efficient storage and release of energy, stabilizing the temperature in the central heating installation and increasing user comfort. The use of a hydraulic coupling ensures optimal temperature stratification in the tank, which translates to higher efficiency of the entire heating system.

Construction and application

The tank is made of lightweight but durable plastic (PE-RT), which eliminates the risk of corrosion and extends its service life. This makes it permanently resistant to rust. It is equipped with two sleeves allowing the installation of up to four temperature sensors, which enables precise control of the system operation and adaptation to individual needs. It also has two immersion tubes that support efficient heat transfer to the heating medium. Designed for standing installation, with a height of 1965 mm and a diameter of 547 mm (without insulation). Connections with a size of 1 1/4 inch facilitate integration with standard installations.

Advantages and benefits

• Efficient temperature stratification: The integrated stratified charging system ensures optimal temperature distribution in the tank, which increases the efficiency of the heat pump and reduces heating costs.
• Durability and reliability: The PE-RT plastic construction guarantees corrosion resistance and long device life. No need to use an anode further simplifies operation.
• Installation flexibility: The ability to connect to various heat sources (heat pump, gas/oil boiler, solar system) and easy system configuration make the tank a universal solution for various heating needs.
• Precise control: Four temperature sensor sleeves allow for accurate monitoring of system operation and adaptation to current conditions.
• Compact design: The tank is relatively compact, and the removable EPS hard foam insulation makes it easy to transport and install – especially in tight spaces.
• Energy efficiency class A: Ensures minimal heat loss and contributes to lower energy bills.
• Universal application: Can be used as a buffer, distribution or solar tank – ideal for modern heating systems.

Please remember that the maximum operating temperature of the tank is 90°C with a maximum working pressure of 3 bar. This is a solid choice for installers looking for a reliable component for building efficient heating systems based on heat pumps, and for users who value comfort and energy savings.
