Combined DHW tank with central heating buffer Roth Thermotank Quadroline TQ-TWK 500 l for heat pumps 1115009952

Hot water tank with buffer for heat pumps – an effective solution for your home

The Roth Thermotank Quadroline TQ-TWK 500 l combi hot water tank with central heating buffer is a modern solution designed for use with heat pumps, but also compatible with other heat sources. Its construction combines the functions of storing domestic hot water and a buffer for the central heating system, which translates into greater energy efficiency of the entire heating system. Lightweight construction and compact dimensions facilitate installation and transport, and the ability to connect up to four sensors allows for precise temperature control and optimization of installation operation.

Construction and advantages

The use of stainless steel in the heat exchanger ensures high corrosion resistance and long-term reliability of the device. The integrated stratified charging system optimizes the temperature distribution in the tank, separating the DHW zone from the heating installation – this translates into higher hot water availability and more stable heating system operation. The removable EPS hard foam insulation minimizes heat loss while facilitating access to the inside of the tank for service or maintenance.

• High efficiency: Stainless steel heat exchanger ensures efficient DHW heating.

• Versatility: Compatible with various heat sources – heat pumps, gas, oil or electric boilers.

• Precise control: Two connections allow connection to four temperature sensors, allowing optimization of the heating system operation and adaptation to individual user needs.

• Easy installation: Lightweight PE-RT plastic construction facilitates transport and installation, even in hard-to-reach places.

• Hygienic heating: The design minimizes the risk of Legionella bacteria development by ensuring a continuous flow of fresh water in the heat exchanger

• No need to use a magnesium anode: The material of execution (PE-RT) eliminates the risk of corrosion, which reduces operating and maintenance costs

• Energy saving: Removable EPS hard foam insulation reduces heat loss, lowering heating and DHW costs.

Operating parameters and safety

The Roth Thermotank Quadroline TQ-TWK 500 l tank is designed for safe and reliable operation. The maximum working pressure is 3 bar, and the maximum operating temperature is 90°C – these parameters ensure safe operation under standard installation conditions. The presence of a immersion tube enables efficient drawing of domestic hot water directly from the tank, and the solid construction guarantees long-term reliability of the device even with intensive use. The capacity of 500 liters makes the tank ideal for both single-family homes and multi-family buildings with moderate demand for hot water and heating power.
