Central heating buffer tank with hydraulic decoupling Roth Thermotank Quadroline TQ-T 500 l for heat pumps 1115009468

Buffer tank for central heating with hydraulic decoupling

This Roth Thermotank Quadroline TQ-T buffer tank with a capacity of 500 liters is designed to work with heat pumps, offering efficient heat storage and distribution in central heating systems. It utilizes an integrated stratified charging system, which ensures optimal temperature distribution within the tank, resulting in higher energy efficiency of the entire system. The hydraulic decoupling allows for independent operation of the heat source and heating circuits, increasing stability and user comfort.

Design and application

The tank is characterized by a lightweight construction made of plastic (PE-RT), which facilitates transport and installation. It does not require the use of an anode, eliminating potential problems related to corrosion and maintenance. This makes it a maintenance-free and durable solution. Access for connecting temperature sensors is provided by two sleeves allowing the installation of up to four sensors in variable positions – allowing for precise monitoring and control of the system. An immersion tube supports efficient heat transfer to the heating medium. The tank is designed for standing installation.

Advantages and benefits

• Efficient heat storage: The integrated stratified charging system ensures optimal use of energy from the heat pump.
• Hydraulic decoupling: Allows independent operation of the heat source and heating circuits, increasing system stability and user comfort.
• Durability and maintenance-free operation: Made of PE-RT plastic, it eliminates the risk of corrosion and the need for an anode.
• Easy installation: Lightweight construction facilitates transport and installation of the tank.
• Precise temperature control: Access to connect up to four temperature sensors allows for accurate monitoring of system performance.
• Compact design: The tank has an easily removable insulation made of rigid EPS foam, which facilitates access to internal components if servicing is required.
• Energy efficiency class A: Guarantees low heat losses and savings in operation.
• Versatility: Designed for central heating, ideal in combination with heat pumps.

Additional information: the maximum operating temperature is 90°C with a maximum working pressure of 3 bar. Connections with a size of 1 1/4 inches ensure compatibility with most heating installations. The diameter of the tank without insulation is 677 mm, and its height is 1965 mm.
