Up to 65 per cent less heat loss with Roth Thermotank Quadroline - Heating processes reduced by a quarter

Recent comparison tests under identical conditions show significant differences in terms of heat loss from hot water storage tanks. The test results show that the Roth Thermotank Quadroline heat storage system exhibits up to 65 per cent less heat loss than standard storage tanks, making it a top performer in energy efficiency.

At the start of the test on Roth’s premises, three variants of the Roth Thermotank Quadroline and a standard storage tank were heated to 60 °C. The cooling behaviour was then measured over the next seven days during standstill at a constant room temperature of approximately 23 °C. All of the Roth Thermotank storage tanks displayed ideal energy efficiency.

Jens Haffner, Head of Energy Systems Research and Development at Roth, explained: “During standstill of the storage tank, with no withdrawals, the standard Thermotank Quadroline with its plastic shell and high-quality EPS insulation exhibits more than 50 per cent less heat loss than a steel storage tank. Equipped with the optional Thermocoat plus, the Thermotank Quadroline can even cut heat loss by more than 65 per cent compared to a steel storage tank. If the storage tank falls below the setpoint temperature, the connected heat generator reheats it. Owing to its lower heat loss, the Roth Thermotank Quadroline can reduce heating processes by a quarter.
