Roth Thermotank Quadroline

Roth Thermotank Quadroline - light, space-saving, variable

The new generation of plastic storage tanks
The innovative Roth Thermotank Quadroline 325 and 500 litre models set new standards in heat storage technology – in terms of energy efficiency, lightness, space-saving design, hygiene, variable operation and resistance to corrosion. The Roth Thermotank is the world's fi rst plastic composite heat storage tank (using fibre/plastic composite technology) to function as a pressure tank with aluminium diffusion protection. The new storage concept enables hygienically safe and forward-looking integration into the domestic drinking water system, as well as off ering the possibility to use solar energy. The tank is extremely light, only around a third of the weight of a comparable conventional steel storage tank, which makes for easier transport and installation. The Roth Thermotank Quadroline has either energy label A or B, depending on the design.


Versatility of use
Thanks to its construction, the Roth Thermotank Quadroline is versatile and can be used in customised system solutions as a stand-alone storage tank or in combination with other devices. For example, it can be used as a central unit in heating applications, as separation or buffer storage tanks, as a solar or combined storage tank or for domestic water heating. The Roth Thermotank Quadroline can be integrated directly into heating systems with a maximum continuous operating pressure of up to three bar.

Conveniently light with maximum temperature consistency
The Roth Thermotank Quadroline is made from a high-quality plastic composite material with aluminium diffusion protection and high-performance EPS insulation on the outside. This material makes the tank extremely light – it weighs only around a third of the weight of a comparable conventional steel storage tank. A further advantage of this specially certified plastic material is that it is resistant to corrosion. Compared with conventional metallic storage tank materials, it is significantly more effective at reducing heat loss. This considerably improves heat storage and has a positive effect on the energy balance of the entire heating system. The unique plastic strengthening matrix (composite) offers a high level of pressure stability. A stable outer cover made from special high-performance EPS insulation enables efficient minimisation of heat loss. The new, lightweight design of this storage tank makes installation and assembly easy – an advantage which installers are sure to appreciate.

At a glance
> pressure-resistant
the world's first, unique composite Thermotank (fibre/plastic composite technology) as a pressure tank for direct integration into heating systems

> diffusion-resistant
the world's first, unique composite Thermotank with aluminium diffusion protection

> corrosion-free
on the inside and outside thanks to the plastic material

> compact
the practical shape is ideal for both renovations and new buildings

> optimum temperature stratification
an innovative stratification unit, which enables loading and extraction at the head and foot ends of the storage tank, ensures optimum temperature stratification in the storage tank. This results in optimised heat distribution, which reduces storage losses and increases efficiency while saving energy at the same time.
