Buffer tank for heating installation Roth Thermotank Quadroline TQ-P 500 l for heat pumps 1115009467

Buffer tank for efficient heating and hot water

Roth Thermotank Quadroline TQ-P 500 l is an innovative solution for storing heat, especially dedicated to installations with heat pumps. This tank is characterized by its lightweight and compact design, which simplifies installation, both in new buildings and during the modernization of existing installations. Made of durable plastic (PE-RT) with an aluminum diffusion barrier layer, it eliminates the risk of corrosion and eliminates the need to use a magnesium anode.

Construction and application

The tank is designed for versatility. It can be integrated with various heat sources – solid fuel boilers, gas, electric, and primarily with heat pumps. Thanks to this, it constitutes a central element of the heating system, enabling optimal use of renewable energy. Equipped with two sleeves for mounting up to four temperature sensors, it allows for precise control of the heating process and monitoring of installation parameters. A capacity of 500 liters provides an adequate reserve of domestic hot water and buffers thermal energy for central heating.

Advantages and benefits

• Lightweight construction: Facilitates transport and installation, especially in hard-to-reach places. The weight of the tank is about three times less than traditional steel counterparts.
• Corrosion resistance: PE-RT material eliminates the risk of corrosion, which translates into a long service life and eliminates the need to replace the magnesium anode.
• High energy efficiency: Thanks to EPS foam insulation and the option of an additional Thermocoat plus thermal jacket (available separately), heat losses are minimized – even by 65% compared to standard tanks. Energy efficiency class A confirms operating savings.
• Versatility: Compatible with various heat sources, allowing flexible adaptation to individual user needs.
• Hygiene: The construction provides hygienic working conditions and minimizes the risk of Legionella bacteria development.
• Simple installation: A standing tank with 1 1/4 inch threaded connections simplifies connection to the heating and DHW installation.
• Safety: Maximum operating pressure of 3 bar guarantees safe operation in standard heating systems.

This tank is not only a heat store – it is an investment in comfort, savings and ecological heating solutions for a home or commercial building.
