The new generation of plastic storage tanks
When using renewable energies, choosing the right storage tank for hot water and heating water is essential for efficient energy utilization. The innovative Roth Thermotanks Quadroline 325, 500 and 850 liters set a new standard in heat storage technology in terms of energy efficiency, lightness, space-saving design, hygiene, variable operation and corrosion resistance. The Roth Thermotank is the world's first plastic composite heat storage tank (fiber/plastic composite technology) as a pressure vessel with aluminum diffusion protection. The storage concept enables hygienically safe and future-oriented integration into the domestic drinking water system and enables the use of solar energy. It is extremely lightweight, weighing only around a third of a conventional comparable steel storage tank, thus simplifying transportation and installation.
Thanks to their design, Roth Thermotanks Quadroline are versatile and can be used in individual system concepts as individual storage tanks or in combination. They can be used as a central unit in heating applications, as a separating or buffer cylinder, as a solar and combination cylinder and in domestic hot water heating systems. Roth Thermotanks Quadroline can be integrated directly into heating systems with a permanent maximum system operating pressure of up to three bar.
The Roth Thermotank Quadroline is made of high-quality plastic composite material with diffusion protection and external high-performance EPS insulation. The use of this material makes it extremely light - its weight is only around a third of that of a conventional, comparable steel storage tank.
Easy to bring into the cellar
Even large volumes can be easily transported up steep and narrow stairs or through narrow doors into a building with two people. This makes the Thermotank Quadroline particularly suitable for use in new builds as well as renovations. Thanks to its low tipping height, the tank can also be easily installed in low cellars.
The Roth Thermotank Quadroline 400 liter plastic thermal store makes renovation even more convenient with a modern storage tank.
The Thermotank Quadroline 400 is available as
> Separate storage tank
> Buffer storage tank
> DHW heater
The low height and therefore also a lower tipping dimension make it even easier to install in low cellar rooms during renovation!
The Roth Thermotank Quadroline received the Homesolute Award in the Environment category and the Plus X Award for High Quality, Design, Functionality and Ecology. The Plus X Award jury also honored the Quadroline as "Plastic Heat Tank of the Year" with the "Best Product of the Year" seal.
The pro-K industry association named the Quadroline Thermotank "Product of the Year". The award stands for outstanding products to whose successful implementation plastic has made a decisive contribution in terms of innovation, design and function.
The Roth Thermotank Quadroline heat storage tank for drinking and heating water has top energy efficiency. Tests carried out by the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg confirm that the Roth Thermotank Quadroline with Thermocoat plus has been awarded the A energy label. The Fraunhofer Institute's test revealed only 59.3 watts of heat retention losses for the 500 liter storage tank with Thermocoat plus and thus up to 65 percent less heat loss compared to standard storage tanks. The Thermocoat plus is available for the 325 and 500 liter cylinders.
The standard version of the Roth Thermotank Quadroline also proved to be very energy-efficient in the Fraunhofer Institute's study and has been awarded the B energy label.
Thanks to the efficient heat storage, the standstill losses of the Roth plastic storage tank are very low. Depending on the model, heating processes can be reduced by a quarter with the Roth Thermotank Quadroline.
The Roth Thermotank Quadroline is the world's first and only pressure-resistant plastic composite hot water storage tank for heating and drinking water. It consists of a thermally stable thermoplastic storage tank plus high-performance fiber composite material with integrated diffusion protection. Compared to metallic storage tank materials, the energy balance of the Thermotank is significantly better, as the thermal insulation properties of the storage material are ideal. A stable outer jacket made of special EPS high-performance insulation also enables efficient minimization of heat loss.
Depending on the application and storage requirements, a system concept is created with the Roth Thermotanks Quadroline. Different areas of application can thus be hydraulically coordinated and assigned.
The Roth Thermotanks Quadroline can be integrated into the domestic heating system and drinking water system in a wide variety of configurations, individually or in battery configuration.
Suitable for central roof systems due to lower static load
The low weight of the Thermotank Quadroline and the ease of transport are ideal prerequisites for installing the storage tank in central roof systems. Due to the lower static load of the plastic storage tank, floor reinforcement is generally not required for use in a roof center, as is the case with conventional steel storage tanks.
The corrosion-free Roth Thermotanks Quadroline are made of a unique plastic composite material with aluminum diffusion protection and external EPS high-performance insulation. Their pressure resistance is 3 bar and the maximum operating temperature is 90 °C.
Roth draws on its decades of manufacturing expertise in plastics processing for the development and production of the Roth Thermotank Quadroline. The company has been manufacturing tanks for various applications since 1963. Alongside energy and water, plastics is one of the company's areas of expertise.
