All systems green: Thermotank Quadroline has energy label A or B depending on the design

Key date for eco-design and energy labelling: 26 September 2015
The countdown has begun: the energy labels we know from household appliances are now coming to heating installations in the cellar. The European Union’s ErP (energy-related products) Directive stipulates the legal framework for designing energy-consumption-related products in an environmentally friendly way and indicating their efficiency. The aim of the efficiency label is to help consumers choose an efficient product.

This means that heat generators and heat storage tanks holding up to 500 litres must be labelled with energy efficiency classes from 26 September 2015. It will not be compulsory to publish information about appliance efficiency until this date, but this obligation must be met from then on. Hot water requirements are set to be made more stringent from 2017.

In addition, due to the new implementing Regulation, hot water and buffer storage tanks holding up to 2,000 litres may now only be put on the European market if they meet efficiency and thermal insulation standards. The labels for heat storage tanks cover classes A to G.

The Roth Thermotank Quadroline heat storage tank for domestic and heating water is extremely energy-efficient. Tests conducted by the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg have confirmed the energy label A rating of the Roth Thermotank Quadroline design with Thermocoat plus. For example, the Fraunhofer Institute’s test measured heat losses (S) of 59.3 watts for the 500-litre storage tank with Thermocoat plus, which is up to 65 per cent less heat loss than standard tanks. The Thermocoat plus is available for the 325- and 500-litre storage tanks. The standard version of the Roth Thermotank Quadroline also proved to be highly energy-efficient in the Fraunhofer Institute’s test and has been awarded energy label B.

The most efficient of its kind
Thanks to its efficient heat storage, the Roth plastic storage tank loses very little heat when it is idle. Depending on the model, the Roth Thermotank Quadroline can reduce heating processes by a quarter. The Roth Thermotank Quadroline is the world’s first and only pressure-resistant plastic composite hot water storage tank for heating and domestic water. It consists of a thermally stable thermoplastic tank and high-performance composite filament material with integrated diffusion protection. The energy balance of the Thermotank is considerably better than metal storage tank materials thanks to the optimal heat insulation properties of the storage tank material. A stable outer cover made from special high-performance EPS insulation also enables efficient minimisation of heat loss.
