An indirectly heated water heater that can be combined with all heating installations.
The Diabolo-shaped coil guarantees an efficient heat exchange with a short heat up time. The FlexTherm Duo HLS-E Solar provides optimum performance combined with a high level of energy efficiency.
Efficient: Minimum heat loss and very fast heating up. Requires little maintenance and no anode. Light weight. Excellent stratification of the water in the vessel. High resistance to chloride (up to 250 ppm).
