Combined DHW cylinder with central heating buffer Roth Thermotank Quadroline TQ-TWK 850 l for heat pumps 1115009994

DHW and buffer tanks – an effective solution for modern installations

Roth Thermotank Quadroline TQ-TWK 850 l combination DHW tank with central heating buffer is an advanced device designed to work with heat pumps, but it will also perform well in systems with solid fuel, oil, gas or electric boilers. Its construction combines the functions of storing domestic hot water and accumulating thermal energy for central heating, which translates into higher efficiency of the entire heating system.

This 850-liter tank is primarily distinguished by the use of innovative materials and technological solutions. A highly efficient stainless steel heat exchanger ensures quick and effective heating of domestic hot water, and an integrated stratified charging system optimizes the temperature distribution in the tank, minimizing heat loss and providing access to hot water at a stable temperature. Additionally, the design allows for precise separation of the DHW zone from the heating installation, which increases comfort and hygiene.

The tank construction has been designed with ease of installation and maintenance in mind. Access to internal components is facilitated by two sleeves allowing the installation of up to four sensors (in the 850 l model, four sleeves are available, allowing connection of up to eight sensors). Removable EPS hard foam insulation facilitates access to components requiring maintenance or replacement, and also allows for quick disassembly if necessary.

• Lightweight tank construction – thanks to the use of PE-RT plastic – facilitates transport and installation, especially in hard-to-reach places.
• No need to use a magnesium anode – the materials used in production eliminate the risk of corrosion, which translates into a longer service life and lower operating costs.
• High energy efficiency – energy class A ensures minimal heat loss and lowers energy bills.
• Hygienic heating – the way water is heated minimizes the risk of Legionella bacteria developing, providing safe and healthy domestic hot water.
• Temperature monitoring possible – the presence of sensor sleeves allows for precise control of the device operation and optimization of the heating system settings.
• Durability and reliability – stainless steel provides corrosion resistance and long-term operation at a maximum working pressure of 3 bar.
