Roth Thermotank Quadroline - energy-efficient, hygienic, safe

Energy efficiency

The Roth Thermotank Quadroline’s efficient heat storage is not only eco-friendly, but also saves money – your money! When compared directly with metal storage tanks of the same size, the Quadroline records up to 65% less heat loss thanks to its plastic composite material, which takes the pressure off your heating and off your wallet too. Depending on the model, heating processes that are necessary for the compensation of the standing losses can be reduced by a quarter, so the investment pays off quickly.


The high-performance composite plastic used prevents corrosion. Hygienic operation is of the utmost importance, particularly for our drinking water. To achieve this, Roth offers an integrated heat exchanger made of corrugated stainless steel piping to heat drinking water based on the constant flow principle. The fresh water is heated when it is required – quickly, safety and cleanly.

Compact safety

The high-performance composite material used guarantees maximum strength. In the development of this heat storage tank, we use technologies that have been tried and tested in space. The composite technology used to achieve the plastic heating tank’s pressure resistance is now also being applied to heat and drinking water storage tanks for building technology. The compact design enables space-saving installation in the corner of a room.

Attractive design, compact shape

The compact design of the Roth Thermotank Quadroline makes optimal use of space. Compared to conventional round storage tanks, the Quadroline’s design stands out thanks to its practical, space-saving dimensions.
